Enterprise SAP transformations, particularly transitions to SAP S/4HANA, are among the most complex change programs organisations undertake. While the technical complexity of SAP migration is one challenge, workforce capacity and capability constraints are frequently underestimated.
Experience repeatedly shows that the harder problem in transformation projects is people. Who will do the work? How do you prevent your best internal staff from burning out trying to run business-as-usual operations while simultaneously driving a multi-year transformation? And how do you ensure that knowledge built during the project doesn't walk out the door the moment go-live is declared?
Workforce planning must be treated as a core governance stream, not an administrative afterthought.
This article explores the structural workforce risks inherent in SAP programs and outlines practical strategies to avoid capability bottlenecks during peak transformation phases.
Why Workforce Bottlenecks Occur in SAP Programs
SAP transformations are not linear IT projects. They involve cross-functional process redesign, data migration and validation, integration with legacy and third-party systems, regulatory and compliance alignment, end-user training and change management. Each of these areas requires business and technical SAP transformation experts who are already responsible for day-to-day operations.
Unlike greenfield digital initiatives, SAP programs typically rely heavily on internal process owners, finance controllers, supply chain managers, and HR specialists, who must define future-state requirements while maintaining ongoing business performance. This dual responsibility creates structural overload.
"Pulling already busy staff into ERP planning can lead to burnout and frustration"
When employees are simultaneously managing their regular responsibilities and absorbing the relentless demands of a transformation programme, quality degrades across both streams. Decisions slow down. Errors accumulate. And the people your project depends on most begin to disengage or exit entirely.
For a transformation to succeed, core team members should expect to dedicate at least 50% of their working hours to the implementation, and the most critical subject matter experts often need to go significantly higher during design and testing phases.
That level of commitment requires offloading existing duties, which itself requires advance planning, cross-training, and sometimes temporary backfilling.
Understanding Peak Workload Phases
SAP transformations are not uniformly resource-intensive. They follow a predictable demand curve, with distinct peaks that organisations must plan for explicitly, yet rarely do.
Blueprint and design phases create early pressure, requiring functional leads to spend intensive time in workshops articulating current-state processes and defining future-state requirements. This phase demands senior business knowledge that cannot be easily substituted.
Data migration and cleansing is chronically underestimated. Large enterprises routinely take months on this step alone due to data volume and complexity. It demands dedicated resource capacity that cannot share attention with operations without sacrificing data quality, the consequences of which cascade through the entire programme.
System integration and testing (SIT/UAT) phases represent another peak, requiring broad cross-functional involvement. These are the stages where understaffing most visibly manifests as delayed testing cycles, insufficient defect resolution time, and compressed cutover windows, all of which dramatically increase go-live risk.
Cutover and hypercare demand absolute peak capacity, often 24/7 resource availability across technical and functional teams simultaneously. For organisations that have been running their internal teams at capacity for 12–18 months already, cutover is where burnout becomes breakdown.
Hiring vs. Temporary Capacity: Making the Right Call
When organisations recognise an impending capacity gap, the instinct is often to hire. It feels like the responsible, long-term solution. But for SAP transformations, which are finite, phase-dependent, and increasingly time-compressed, full-time permanent hiring is frequently the wrong answer, and it is an expensive one.
The core issue is timing. A full-time hire takes months to recruit, onboard, and reach productivity. By the time a permanent employee is contributing meaningfully to an S/4HANA programme, the peak phase that justified the hire may have already passed. The talent you hired at premium rates now needs to be redeployed, retrained, or let go.
Capacity planning decisions for SAP programmes need to be made 12 to 18 months before peak phases, not reactively when the pressure is already felt.

Many organisations address peak workload phases through structured SAP team augmentation frameworks, bringing in specialist contractors, consulting resources, and managed service partners specifically calibrated to the programme's phase demands. This approach allows internal staff to maintain operational continuity while augmented capacity absorbs the implementation spikes.
The key is not simply adding consultants, but designing a controlled capacity model aligned with governance, accountability, and long-term knowledge retention.
Building a Workforce Strategy That Holds
Large-scale SAP transformations are as much workforce programmes as they are technology initiatives. Capability bottlenecks, if unmanaged, can delay decision-making, weaken testing quality, increase employee burnout, and jeopardise long-term system adoption.
The organisations that navigate SAP transformations without major capability disruptions share a common characteristic: they treat workforce planning with the same rigour as technical architecture.
They build a structured capacity plan before the programme begins. They map internal talent to each transformation phase, identify capability gaps early, and make deliberate decisions about how those gaps will be addressed, whether through redeployment, temporary augmentation, permanent hiring, or partner-managed services.
Crucially, these decisions are made proactively rather than reactively.
HR leaders should be involved at the earliest stages of transformation planning. Rather than responding to urgent hiring requests during testing or go-live, HR can work closely with transformation leadership to forecast talent demand in advance. This includes determining which roles justify permanent hiring, where interim expertise may be more appropriate, and how onboarding timelines may influence programme milestones.
The SAP ecosystem is already experiencing talent constraints. Consulting rates continue to rise, experienced programme leaders are engaged across multiple simultaneous initiatives, and the pool of professionals with both deep ECC knowledge and S/4HANA implementation experience remains limited. In this environment, workforce planning cannot be deferred.
When workforce strategy is embedded early and managed deliberately, SAP transformations are far more likely to deliver sustainable results, both technically and organisationally.
