In the complex world of enterprise system implementations, whether SAP S/4HANA, Oracle Cloud, Workday, Microsoft Dynamics and more, a well-managed partnership with your system integrator (SI) is one of the greatest determinants of success. Yet even organizations that carefully negotiate initial contracts with their SI often overlook a crucial element as the program unfolds: updated and transparent staffing models.
Failing to insist on regular updates to staffing models can quietly derail your timeline, inflate costs, and ultimately compromise business value. Here’s why you should treat updated staffing models not as a nice-to-have, but as a non-negotiable governance mechanism.
Visibility into Resourcing Risks and Gaps
One of the most immediate benefits of receiving regular staffing updates is the ability to identify and mitigate resourcing gaps before they affect delivery.
System integrators often experience high turnover, shifting internal priorities, and concurrent client demands. What was promised at the outset of the program may not reflect reality three, six, or nine months into your program. If you’re relying on stale staffing models, you may not know that a critical architect has rolled off or that planned ramp-ups have been quietly delayed.
By requiring frequent and detailed staffing model refreshes, ideally aligned with key phase gates, you gain early warning of resource shortfalls and can take proactive action, whether by escalating within the SI, engaging additional partners, or reallocating internal resources.
Alignment with Program Phasing and Complexity
Your system implementation is not static. As the program matures and shifts from design to build, testing, deployment, and stabilization, the required mix of roles and skills evolves dramatically.
If your SI’s staffing plan isn’t evolving accordingly, you may end up with the wrong resources at the wrong time, an expensive inefficiency that slows progress and drives scope creep. Updated staffing models help validate whether the SI is adapting its delivery organization to meet the needs of the current and upcoming program phases.
This also reinforces accountability. If you’re paying for 20 full-time equivalent (FTE) test analysts in a month where no test scripts are being executed, that’s a red flag that deserves your attention.
Cost Management and Scope Transparency
Staffing is the largest controllable cost lever in most SI contracts. But without updated staffing models tied to timesheets and actuals, it becomes exceedingly difficult to ensure you’re paying for the resources you actually need.
Too often, clients are surprised by budget overruns only to discover that staffing remained flat even as program needs diminished or ballooned unexpectedly due to poorly managed change requests.
A disciplined practice of comparing current staffing models to previous versions, aligned with progress against deliverables, gives you the transparency needed to challenge unnecessary roles, push back on rate increases, and identify opportunities to optimize the team structure.
Governance and Performance Management
Updated staffing models serve as a powerful performance management tool. They allow you to assess whether the SI is honoring its resource commitments, not just in number, but in experience level, continuity, and mix of onshore/offshore allocation.
They also support informed governance conversations. Are senior architects showing up as promised? Is there an overreliance on junior resources? Has the proportion of billable vs. shadowing staff changed? These are questions that staffing models can help answer and that can inform contract compliance reviews or potential financial recoveries.
Change Is Inevitable, But It Must Be Managed
Change is a given in any large-scale implementation. Business priorities evolve. Technical designs are refined. External dependencies shift. All of this has a ripple effect on staffing.
Rather than resisting this reality, leading organizations embrace it by embedding updated staffing models into their broader change management and governance framework. By making staffing transparency a regular agenda item, and not an afterthought, they maintain control even in the face of volatility.
Final Thoughts
Updated staffing models are not just an operational artifact; they’re a strategic enabler of program success. If your system integrator is not proactively providing refreshed views into its delivery team, it’s time to demand it.
At UpperEdge, we help clients establish contractual mechanisms and governance structures that ensure this kind of visibility is built in from day one. Our Project Execution Advisory Service helps organizations highlight and mitigate these risks long before they become costly problems.
