A practical guide to SAP S/4HANA implementation for UK businesses, covering migration, deployment, data, integration, testing, and go-live.
Moving to SAP S/4HANA is much more than installing a new ERP system. It is a transformation of the way an organisation manages finance, procurement, sales, inventory, manufacturing, supply chain, data, and integrations.
Moving to SAP S/4HANA is much more than installing a new ERP system. It is a transformation of the way an organisation manages finance, procurement, sales, inventory, manufacturing, supply chain, data, and integrations.
For a business that has never run SAP, this may mean implementing a new enterprise platform. For an organisation already using SAP ECC, the challenge is different: existing processes, customisations, data, interfaces, and business history all need to be assessed before deciding what should move to the new environment and what should change.
This is particularly important for UK enterprises operating across multiple legal entities, sites, warehouses, countries, or legacy systems. A finance process, for example, may depend on information coming from procurement, sales, inventory, banking, tax, and external applications.
A successful programme therefore needs to connect:
Business Strategy → Process Design → SAP Architecture → Data → Integration → Implementation → User Adoption → Continuous Improvement
SAP currently offers different S/4HANA cloud approaches, including SAP Cloud ERP Public Edition and SAP Cloud ERP Private, with different levels of standardisation and flexibility. The right choice depends on the complexity of the business, existing SAP investments, customisation requirements, integrations, and long-term strategy.
This guide explains what SAP S/4HANA implementation involves, how organisations choose between different implementation and deployment approaches, what happens to existing SAP ECC environments, how data and integrations are handled, what UK-specific considerations may apply, and how to plan the programme from assessment to go-live.
SAP S/4HANA implementation is a complex transformation that can involve significant challenges across business processes, data migration, integrations, customisation, testing, and change management.
Organisations move to SAP S/4HANA for a range of business and technology reasons, including:
For many organisations, several of these drivers come together in a single S/4HANA programme.
Many organisations are moving away from older SAP ERP environments such as ECC. The transition provides an opportunity to modernise finance, procurement, supply chain, manufacturing, and other core business processes, rather than simply replacing the underlying technology.
Large organisations may have different ways of performing the same process across countries or business units.
For example:
UK Company → Purchase Order
German Company → Purchase Order
US Company → Purchase Order
A global S/4HANA programme can establish a common process and data model while preserving local differences where they are genuinely required.
Legacy SAP environments can contain years of custom code, outdated interfaces, and process workarounds.
An S/4HANA transformation creates an opportunity to review the existing landscape and decide what should be:
Keep → Replace → Simplify → Retire
This can reduce complexity and support a cleaner, more maintainable ERP environment.
Case study: Preparing for SAP ECC to S/4HANA Migration with a Clean Core Approach - LeverX helped simplify the SAP infrastructure and prepare the environment for a smoother S/4HANA migration.
Cloud ERP can change how organisations manage infrastructure, upgrades, scalability, security, and ongoing innovation.
For some businesses, moving to SAP Cloud ERP is also part of a broader technology strategy focused on reducing legacy infrastructure, adopting more standardised operating models, and creating a stronger foundation for AI and automation.
S/4HANA can provide a more integrated foundation for financial and operational data, helping organisations connect transactions with reporting, analytics, automation, and AI.
Instead of separate views across departments, the goal is to create a more connected picture of how:
Finance + Procurement + Sales + Inventory + Operations
affect one another.
A modern S/4HANA landscape can provide a stronger foundation for workflow automation, analytics, and AI-enabled business processes.
The value comes from embedding automation into real business processes rather than introducing AI as a separate technology layer.
Acquisitions, new business units, international expansion, and additional plants or distribution centres can expose limitations in an existing ERP landscape.
S/4HANA can provide a platform that is easier to standardise, integrate, and scale as the organisation grows.
For many organisations, S/4HANA is one stage of a longer transformation journey:
S/4HANA → Cloud → BTP → Data → Automation → AI
The key point is that S/4HANA should have a business case beyond simply replacing an old SAP version. The strongest programmes use the transition to simplify processes, reduce complexity, improve data and integration, and create a foundation for future business transformation.
LeverX tip: Define the business case and assess the current SAP landscape before choosing the S/4HANA implementation approach. Set clear priorities for ERP modernisation, process standardisation, cloud adoption, growth, and cost reduction, and estimate the expected investment and business value upfront. This helps determine what should change, what should stay, and where the transformation can deliver the greatest value.
SAP S/4HANA is SAP’s modern Enterprise Resource Planning (ERP) platform, built on the SAP HANA in-memory database.
An ERP system connects the core processes that keep a business running. Instead of finance, procurement, sales, inventory, and production working as separate areas, S/4HANA allows them to work with shared data and connected processes.
For example, a customer order can connect sales with inventory, delivery, billing, and accounting:
Customer Order → Inventory Check → Delivery → Billing → Accounting
The same applies to procurement:
Purchase Requisition → Purchase Order → Goods Receipt → Supplier Invoice → Payment
And to manufacturing:
Production Plan → Materials → Production → Finished Goods → Inventory → Sales
The key idea is process integration. An activity in one part of the business can automatically update data or trigger the next step in another, reducing manual handovers, duplicate data entry, and reconciliation between separate systems.
S/4HANA supports core business areas including:
For business users, this means a more connected view of what is happening across the organisation. Finance can see the financial impact of operational transactions, procurement can track spend and purchasing activity, and supply chain teams can work with more up-to-date information on orders, materials, and inventory.
S/4HANA can also strengthen controls, governance, auditability, and regulatory reporting through standardised processes, workflows, authorisations, and transaction records. This can make it easier to monitor activity, investigate discrepancies, and provide evidence for audits.
For organisations operating across multiple legal entities, sites, business units, or countries, S/4HANA can provide a common enterprise foundation, while still allowing local requirements and specialist applications to be integrated where needed.
In practice, the value of S/4HANA is not only about processing transactions. It is about connecting:
Processes + Data + Controls + Integration + Analytics → Better Business Visibility and Governance
Moving to S/4HANA is not just a technical upgrade. It can change how the business processes transactions, manages data, controls activities, and works across functions.
In practice, this can mean moving from a fragmented way of working towards a more integrated and automated model:
Legacy ERP + Spreadsheets + Custom Interfaces + Manual Processes
↓
Integrated ERP + Standard Processes + Real-Time Data + Automation
This can affect everyday operations across finance, procurement, sales, warehouse, manufacturing, and logistics. For example, a customer order can flow through connected activities:
Customer Order → Inventory → Delivery → Billing → Accounting
The same principle can apply to procurement and manufacturing, reducing manual updates and reconciliation between disconnected systems.
The scale of the change depends on the implementation approach. Brownfield typically focuses on modernising the existing SAP environment, while greenfield allows greater freedom to redesign and simplify processes.
The way S/4HANA is delivered also depends on the organisation’s needs. SAP offers different deployment models, with Public Edition providing a more standardised approach and Private Edition offering greater flexibility for more complex business environments.
For a broader comparison of Public Cloud, Private Cloud, On-Premise, and Two-Tier ERP, see our SAP S/4HANA Deployment Models Guide.
Public Edition is built around standardised, preconfigured business processes delivered in the cloud. It is best suited to organisations that are prepared to adopt SAP’s standard processes and keep customisation to a minimum.
For the business, this can mean more consistent processes across teams and countries, fewer custom developments, and a simpler system to maintain and update.
A simplified approach is:
Standard SAP → Configure → Extend Where Necessary
The principle is to use the standard process wherever possible and only introduce extensions where there is a clear business need.
Private Edition provides greater flexibility for organisations with more complex requirements or significant existing SAP investments.
It can be more suitable where the organisation has:
For the business, the main advantage is greater freedom to retain, adapt, or redesign existing processes where the standard SAP approach may not be sufficient. This flexibility can be important for complex organisations, but it can also result in a more complex transformation and greater need for governance.
In simple terms, the choice often comes down to a balance between standardisation and flexibility:
Public Edition → More Standardisation
Private Edition → More FlexibilityThe right choice depends on the organisation’s business complexity, existing SAP landscape, level of customisation, integration needs, and long-term transformation strategy.
Once the target deployment model is defined, the next question is how the organisation will move from its current ERP environment to S/4HANA.
There are three main approaches: Greenfield, Brownfield, and Selective Data Transition. The right choice depends largely on how much of the existing environment the organisation wants to keep versus redesign.
A Greenfield implementation starts with a new S/4HANA environment rather than carrying the existing ERP configuration forward.
The journey typically looks like:
Current Business Processes → Future-State Design → Fit-to-Standard → New S/4HANA → Data Migration
This gives the organisation more freedom to simplify processes, remove unnecessary customisation, and establish a more consistent operating model.
It can be particularly attractive where the existing ERP has:
The main trade-off is that business users may need to change established ways of working and adapt to the redesigned processes.
A Brownfield approach converts the existing SAP ERP environment to S/4HANA while keeping a significant part of the existing configuration, processes, and business history.
The journey can look like:
SAP ECC → Readiness Check → Remediation → Conversion → S/4HANA
This approach can reduce disruption where existing processes still work well and the organisation places a high value on continuity and preservation of the current setup.
However, conversion alone does not remove legacy problems. Existing customisations, inefficient processes, or outdated data structures may still need to be addressed.
Selective Data Transition takes a middle path. Rather than moving everything as it is or starting completely from scratch, the organisation selects which data, processes, and business structures should move to the new S/4HANA environment.
It can be useful in situations such as:
This approach can provide more flexibility, but it also requires careful decisions about what should be retained, what should be redesigned, and what should be left behind.
Ultimately, the choice of implementation approach depends on the organisation’s starting point, business priorities, appetite for change, and target operating model.
Whatever approach is chosen, an S/4HANA programme can be broken down into a number of stages. For business users, the overall journey can be summarised as:
Assess → Design → Configure → Integrate → Migrate → Test → Deploy → Stabilise
The project starts by understanding the current environment and identifying what needs to change.
This can include:
The outcome is a clear view of where the organisation is today and what needs to be addressed.
Practical recommendation: Start with an SAP assessment before committing to the full transformation. It can help identify key gaps, risks, customisations, dependencies, and areas where S/4HANA could deliver the greatest business value, while providing a basis for the implementation roadmap.
The team defines how the future environment should work.
This includes decisions about:
For the business, this is where important choices are made about how processes will work after the transformation.
Design the future state, not just a copy of the current one. Use Fit-to-Standard to challenge existing processes and identify where the business can simplify, standardise, or redesign the way it works.
The S/4HANA environment is configured to support the agreed processes.
Where standard SAP already meets the business requirement, the preferred approach is normally to use the standard process rather than recreate it through custom development.
Avoid changing SAP just because the current process works differently. Challenge each requirement against the standard SAP process first, and customise only where changing the business process is not practical or would create significant business impact.
S/4HANA is connected to other applications and external systems that the business relies on.
For example:
S/4HANA ↔ Bank
S/4HANA ↔ E-commerce
S/4HANA ↔ MES
S/4HANA ↔ WMS
S/4HANA ↔ Tax / Regulatory Systems
Do not automatically recreate all legacy integrations. Review each interface, confirm whether it is still needed, and use the S/4HANA standard capability where possible. This is a good opportunity to remove redundant integrations and simplify the landscape.
Required data is extracted from the legacy environment, transformed, loaded into S/4HANA, and validated.
This can include master data, open transactions, balances, and selected historical information, depending on the implementation approach.
Do not migrate data simply because it exists in the legacy system. Agree what the business actually needs, clean it before migration, and define early what should be migrated, archived, or left behind.
The new environment is tested by both technical teams and business users.
Testing should cover not only individual transactions, but also end-to-end business processes across multiple functions.
For example:
Customer Order → Delivery → Billing → Accounting
Test the processes that are critical to the business, not just the system functions. Involve the actual business users early and test realistic scenarios, including exceptions and failure cases - not only the “happy path”.
Once testing is complete, the final data migration and cutover activities are performed, and the organisation moves to the new production environment.
Treat go-live as a business event, not only an IT activity. Agree clear cutover responsibilities, minimise critical changes around go-live, and make sure users, support teams, data, and key business processes are ready from day one.
After go-live, the project team supports users, resolves early issues, and monitors the new processes and system.
The aim is to move from project mode to stable day-to-day operations.
Do not define success as simply “going live”. Monitor key business processes and user issues closely after go-live, and use the first weeks to fix problems, improve adoption, and fine-tune the new way of working.
Before starting an S/4HANA programme, it is useful to assess whether the organisation is ready for the change. Readiness is not only about technology — it also covers processes, data, people, and governance.
A practical readiness check can look at:
Process Readiness → Data Readiness → Architecture Readiness → Integration Readiness → People Readiness → Governance Readiness
Key questions include:
Do not wait until the project starts to discover readiness gaps. An early SAP assessment can help identify the main risks, dependencies, and areas that need attention before the implementation begins.
An organisation does not need to have everything solved before starting, but it should understand where the major gaps and dependencies are.
SAP Activate provides a structured methodology for S/4HANA implementations:
Discover → Prepare → Explore → Realize → Deploy → Run
In practical terms:
Discover defines why the organisation is transforming and what it wants to achieve.
Prepare establishes the project team, governance, environments, and implementation plan.
Explore is where the business reviews SAP standard processes, challenges existing ways of working, and confirms the target design.
Realize covers configuration, development, integrations, data migration, and testing.
Deploy covers final cutover and go-live.
Run focuses on stabilisation, support, optimisation, and continuous improvement.
A key point is that Explore and Realize are not just technical phases. Business users need to be involved in decisions about how processes, data, and controls will work in the new environment.
Fit-to-standard is one of the key principles of an S/4HANA implementation.
Instead of asking:
“How can we make SAP work exactly like our old system?”
the project starts with:
“Can the SAP standard process meet the business requirement?”
A typical decision process is:
Existing Process → SAP Standard → Gap → Business Justification → Decision
The outcome may be:
Adopt Standard → Configure → Extend → Customise Only When Necessary
This approach can reduce complexity, lower maintenance effort, and make future upgrades easier.
Challenge legacy processes before reproducing them. A difference from the old ERP is not automatically a reason for customisation.
Clean Core extends the same principle to the overall S/4HANA architecture.
The aim is to keep the ERP core as close as practical to standard SAP functionality, while using supported extension and integration capabilities outside the core where additional functionality is required.
A simplified model is:
SAP S/4HANA Core → Standard ERP Processes
SAP BTP → Extensions + Integration + Automation
SAP BTP provides capabilities for integration, application development, automation, data, and extensions.
This can help reduce technical debt and keep the ERP environment easier to maintain and evolve.
Before building a custom solution inside S/4HANA, check whether the requirement can be addressed through standard functionality, configuration, or an extension outside the core.
Data migration is often one of the most challenging parts of an S/4HANA programme.
Depending on the implementation approach, organisations may need to migrate:
But not everything in the old system needs to be moved.
A practical decision can be based on:
Business Value + Operational Need + Regulatory Requirement + Migration Effort
The migration process typically looks like:
Discover → Profile → Cleanse → Map → Transform → Load → Validate → Reconcile
Practical recommendation: Decide early what should be migrated, archived, or left behind. Moving poor-quality or unnecessary data into the new system only transfers the problem.
S/4HANA rarely operates as a standalone system. Most organisations need to connect it to other applications and external platforms.
For example:
S/4HANA ↔ CRM
S/4HANA ↔ E-commerce
S/4HANA ↔ MES
S/4HANA ↔ WMS
S/4HANA ↔ Banks
S/4HANA ↔ Tax / Regulatory Platforms
S/4HANA ↔ Data Platforms
SAP Integration Suite and BTP can support integration between SAP and non-SAP applications across hybrid environments.
Do not automatically recreate every legacy interface. Review each integration and ask whether it is still needed, whether SAP standard functionality can replace it, and whether the data flow can be simplified.
A UK S/4HANA programme may need to combine a global process template with local requirements.
Depending on the organisation, this can include:
The principle is:
Global Process Standardisation + Necessary UK Localisation
The objective is not to create a completely separate UK solution, but to maintain common processes while addressing genuine local requirements.
Testing should focus on business scenarios, not only individual SAP functions.
For example:
Procurement:
Purchase Requisition → Purchase Order → Goods Receipt → Invoice → Payment
Sales:
Sales Order → Delivery → Billing → Receivables → Cash
Manufacturing:
Demand → Planning → Materials → Production → Quality → Inventory
Testing can include:
Test the processes that are critical to the business, including realistic exceptions and failure scenarios. The objective is to prove that the business can operate, not simply that individual SAP transactions work.
Cutover is the point at which the organisation moves from the old ERP environment to S/4HANA.
A typical sequence is:
System Freeze → Final Data Extraction → Data Load → Reconciliation → Business Validation → Go-Live
The cutover plan should define:
For finance teams, timing may also need to consider month-end, year-end, payment runs, payroll, and other critical activities.
Practical recommendation: Treat cutover as a business-critical event, not only an IT task. Clear ownership and rehearsals can significantly reduce go-live risk.
Going live is not the end of the transformation.
During hypercare, teams focus on:
Once the environment is stable, the focus can move to continuous improvement:
Stabilise → Measure → Optimise → Automate → Innovate
This is where organisations can introduce additional analytics, automation, BTP extensions, and AI capabilities where they provide clear business value.
Define ownership for the post-go-live environment before go-live itself, including support, monitoring, issue resolution, and continuous improvement.
There is no standard SAP S/4HANA implementation price. As a general UK planning benchmark, costs may look like:
| Project scope | Indicative implementation cost |
| Mid-market, single entity | £200k–£600k |
| Mid-market, multi-entity | £500k–£2m |
| Large enterprise | £2m–£10m |
| Complex global transformation | £10m+ |
These are indicative planning ranges, not fixed prices or quotes from SAP or LeverX. The final budget depends on several key parameters, including:
A realistic budget should therefore consider:
SAP Subscription / Licensing + Implementation + Migration + Integration + Change Management + Support
For a deeper breakdown of SAP S/4HANA implementation costs, see our SAP S/4HANA Implementation Cost Guide.
One of the most common mistakes is treating S/4HANA as a technical replacement for the existing ERP. Simply transferring legacy processes, customisations, and workarounds can carry unnecessary complexity into the new environment.
Before migrating, organisations should assess which processes still deliver business value, which can be simplified, and which can be replaced with standard S/4HANA capabilities. Fit-to-Standard can help identify where legacy processes can be redesigned rather than replicated.
Data migration is often underestimated until problems appear during testing. Poor-quality master data, duplicates, inconsistent formats, missing records, and unclear ownership can create delays and affect business processes after go-live.
Data should therefore be assessed and cleansed early. Organisations should define what needs to be migrated, what can be archived, and who owns data quality before migration activities begin.
Integrations can have a major impact on the S/4HANA architecture and implementation timeline. Interfaces with banks, suppliers, customers, logistics platforms, manufacturing systems, CRM, and other third-party applications need to be understood early.
Leaving integration design until late in the programme can create unexpected dependencies, additional development, testing effort, and cutover risks. A complete integration inventory and target architecture should be established during the design stage.
S/4HANA changes more than technology. It can affect business processes, roles, controls, reporting, and the way employees perform their daily work.
A technically successful implementation can still create operational problems if users are not prepared for the changes. Business stakeholders should therefore be involved throughout the programme, with clear ownership, training, communication, and change management.
Testing only standard scenarios does not reflect how the business operates in practice. Real-world processes include exceptions such as rejected invoices, missing master data, pricing discrepancies, failed interfaces, blocked deliveries, and incomplete transactions.
Testing should cover end-to-end business processes and realistic exception scenarios, with particular attention to critical integrations and processes that span multiple functions.
Go-live is not the end of an S/4HANA transformation. Organisations need clear ownership and support processes to resolve issues, monitor system performance, and address problems that emerge once real business volumes and scenarios are running.
A structured hypercare period, followed by ongoing application management and continuous improvement, can help stabilise the new environment and ensure that the organisation continues to realise value from S/4HANA.
An S/4HANA transformation is not just a technical migration. For business leaders, the key questions are what needs to change, which decisions need to be made, what the business gets at each stage, and where the main risks lie.
Assess the current SAP landscape, business processes, data, customisations, integrations, and operational pain points. The goal is to establish what should be retained, what needs to change, and where the biggest risks and dependencies are.
Choose the right approach - greenfield, brownfield, or selective transformation - and agree on the target operating model, priorities, budget, and timeline. This is also the stage to define which business areas should be transformed first.
Define how Finance, Supply Chain, Procurement, Manufacturing, Sales, and other functions should operate in S/4HANA. The emphasis should be on adopting standard SAP capabilities where possible and avoiding unnecessary customisation.
Configure S/4HANA, migrate and validate data, connect surrounding systems, and develop only the extensions the business genuinely needs. AI-assisted tools can automate parts of migration, data management, testing, and documentation, helping reduce manual effort and potentially accelerate delivery.
Test end-to-end processes with real data and business users. Critical workflows such as order-to-cash, procure-to-pay, financial close, reporting, and supply chain operations should be validated before go-live.
Execute the cutover, move to the new environment, support users, and resolve issues during the initial stabilisation period. The real measure of success is business continuity and adoption — not simply getting the system live.
Once the core platform is stable, the organisation can introduce further automation, analytics, SAP BTP capabilities, and AI use cases to improve efficiency and create additional business value.
For business leaders, the most important decisions usually happen before the build starts: which processes to standardise, what data to migrate, what to customise, which systems to integrate, and how much organisational change to introduce at once.
The implementation partner can have a significant impact on project cost, delivery risk, and the quality of the resulting SAP landscape.
Key capabilities to look for include:
Useful questions include:
The strongest partner should be able to explain the business impact of technical decisions, not simply describe SAP functionality.

SAP S/4HANA implementation is more than an ERP technology upgrade. It is a business transformation that affects processes, data, integrations, people, controls, and the way an organisation operates.
For this reason, the most important decisions are often made before implementation begins. Understanding the current SAP landscape, assessing business and technical readiness, defining the target architecture, and agreeing on the right transformation approach can help organisations reduce risk and avoid carrying unnecessary complexity into the new environment.
A practical S/4HANA transformation journey is:
Assess → Define the Strategy → Decide → Design → Build → Migrate → Test → Deploy → Optimise
For UK organisations, this also means balancing global process standardisation with genuine local requirements, while modernising legacy systems, improving data quality, and keeping unnecessary customisation under control.
The transformation can create an opportunity to go beyond simply replacing legacy ERP. With the right strategy and roadmap, organisations can simplify processes, strengthen integration, improve business visibility, establish a cleaner SAP core, and create a foundation for automation, analytics, and AI.
Starting with the right assessment and consulting approach can help turn a complex S/4HANA migration into a structured business transformation - with clear priorities, a defined target state, and a roadmap aligned with long-term business goals.
It is the process of assessing, designing, configuring, integrating, migrating, testing, and deploying S/4HANA to support an organisation's business processes and transformation goals. The implementation may also involve process redesign, data cleansing, change management, and post-go-live support.
It depends on the scope, integrations, data complexity, customization, and implementation approach. As a general industry planning benchmark, a focused implementation may take 6–9 months, a larger brownfield project around 12–15 months, and a greenfield transformation around 15–21 months. Complex global rollouts can take 18–24+ months.
These are indicative industry estimates, not timelines provided by LeverX or SAP for a specific implementation. An initial assessment is needed to determine a realistic timeline based on countries, users, integrations, data, and rollout scope.
Greenfield creates a new S/4HANA environment around redesigned and standardised processes. Brownfield converts an existing SAP ERP environment while retaining more of the existing configuration, processes, and history. The right approach depends on the organisation's transformation goals, current SAP landscape, and appetite for process change.
The choice between Public and Private Edition depends on business complexity, standardisation, existing SAP investments, customisation, integrations, regulatory requirements, and long-term strategy. An SAP assessment can help determine which model is better aligned with the organisation's requirements.
SAP Activate is SAP's implementation methodology with six phases: Discover, Prepare, Explore, Realize, Deploy, and Run. It provides a structured framework for planning, designing, implementing, deploying, and continuously improving SAP solutions.
Fit-to-Standard starts with SAP's standard business processes and introduces changes only where there is a justified business requirement. This approach can help reduce unnecessary customisation and support a cleaner, more maintainable SAP environment.
Clean Core aims to keep the S/4HANA core as close as practical to standard SAP functionality while using supported extensions and platforms such as SAP BTP for additional capabilities. This can make future upgrades and ongoing system management more manageable.
Depending on the project, organisations may migrate master data, financial balances, open items, inventory, assets, and selected historical information. The scope should be based on business, operational, reporting, and regulatory requirements. Data quality and cleansing should be addressed before migration to reduce downstream issues.
Yes. S/4HANA can integrate with SAP and third-party applications using technologies such as SAP Integration Suite and SAP BTP. Integration planning should cover existing interfaces, data flows, APIs, EDI, and other systems that need to remain connected after go-live.
Testing should cover data migration, integrations, end-to-end business processes, user acceptance, performance, security, and cutover. Organisations should also validate critical business scenarios and confirm that users, support teams, and operational processes are ready for go-live.
Not necessarily, but most transformation programmes use the opportunity to standardise and simplify processes rather than reproduce every legacy workflow. The extent of process change should be defined during the assessment and design stages.
LeverX can start with an AI-assisted assessment of an organisation's current SAP landscape, business processes, data, customisation, and integrations to identify transformation opportunities, risks, and priorities. We can then validate the findings through Fit-to-Standard workshops, assess where processes can adopt standard SAP capabilities, and define the right implementation approach and roadmap. From there, LeverX can support the full S/4HANA transformation lifecycle, including architecture, migration, implementation, integration, testing, go-live, and ongoing optimisation.
