Is SAP Complexity Real, Or Are We Blaming The Wrong Thing?

By Laurence Harper -

SAP complexity comes up in almost every serious transformation discussion. It comes up in S/4HANA conversations, in SuccessFactors conversations, and in wider SAP platform decisions where clients are weighing long term value against delivery and BAU effort.

The concern is valid. There is history behind it, and there are enough poor implementations in the market to make people cautious. But in many cases, what gets labelled as SAP complexity is not the platform itself. It is the result of weak governance, poor design discipline, unclear ownership, and years of workaround behaviour that no one has cleaned up.

That distinction matters. If you misdiagnose the cause, you spend money in the wrong place.


Key Takeaways

  • Most SAP complexity comes from operating model and governance choices, not the software alone
  • BAU effort is driven by ownership, scope control and process discipline, not just platform brand
  • “Configuration complexity” is often exception creep in disguise
  • Integration complexity is usually a data and support model issue across the estate
  • UI and user experience drive perceived complexity more than teams admit
  • Many SAP decisions are still shaped by old on-prem stories, not current cloud product reality

What People Usually Mean When They Say “SAP Is Complex”

When someone says SAP is complex, they are rarely talking about one thing. They are usually describing a mix of concerns that have been bundled together into a single label.

Sometimes they mean the team thinks it will need too many people to run. Sometimes they mean changes will be slow and consultant-led. Sometimes they mean the user experience looks heavy. In other cases, they mean integrations, upgrades, approvals, and release cycles all look like they will add operational drag.

Those are all fair concerns. The problem is that they get collapsed into one phrase, SAP complexity, and that makes it harder to deal with them properly. Each one has a different root cause. Each one needs a different response.


BAU Effort, This Is Usually an Operating Model Question

One of the strongest SAP complexity objections is the assumption that a large platform automatically requires a large internal team. It sounds sensible on the surface. If the system is enterprise grade, then the support model must be enterprise scale too.

In practice, that is only partly true.

BAU effort is usually shaped by how well the organisation controls process variation, who owns design decisions after go live, and how disciplined the team is about change. A well-run SAP environment with clear ownership can operate with a lean support model. A poorly governed environment can create high BAU overhead in almost any platform, including systems marketed as simple.

This is where many programmes go wrong. They compare software, but they do not define the run model. Then the support burden shows up later and gets blamed on the product.


Configuration Complexity, SAP Often Gets Blamed for Governance Failures

SAP gives teams a lot of flexibility. That is one of the reasons large organisations buy it. The issue starts when flexibility is treated as permission to accept every exception.

This is how SAP complexity builds in the background. One approval path gets an extra step. One business unit wants a different process. A local field gets added for a valid reason. Another team asks for something similar, but slightly different. Six months later, the process is harder to explain, harder to test, and harder to change.

That is not SAP being inherently bloated. That is poor design discipline.                                                                                            

Any configurable platform will behave the same way if governance is weak. SAP simply makes the consequences visible faster because it sits at the centre of key business processes.


Old SAP Stories Still Shape Current SAP Decisions

A lot of SAP complexity concerns are inherited from older delivery models. Senior stakeholders still remember on-prem estates, bespoke developments, long upgrade cycles, and months of testing for changes that should have been routine. 

Those experiences were real. They still influence buying decisions.

But they are not the full picture now. Cloud SAP products changed the model. The release cadence, ownership split, and upgrade mechanics are different. That does not mean there is no internal work, there is. Teams still need to review changes, test core processes, and manage user impact. But it is not the same as the old customer-managed world that many people still have in mind.

This gap between old perception and current product reality is one of the biggest drivers of SAP complexity as a narrative.


Integration Complexity Is Usually an Enterprise Issue, Not a SAP Issue

Another common concern is what happens when SAP sits alongside non-SAP systems. This comes up constantly in banks and insurers, where estates are mixed and there is no appetite for a full platform standardisation move in one go.

Again, the concern is fair. Integrations do create risk and BAU overhead.

But this is not a SAP-only problem. Any serious HR, finance, procurement, or risk platform will need to exchange data with the rest of the estate. The real pressure points are usually data ownership, interface monitoring, support responsibilities, and how teams work across functional boundaries when something goes wrong.

If those basics are not defined, every integration feels fragile. SAP then gets labelled as complex because it is one part of the chain, when the actual issue sits in cross-team operating discipline.


Felt Complexity Starts With the User Experience

This is the part transformation teams often underestimate.

Users do not judge SAP complexity by architecture diagrams or feature depth. They judge it by what they can do in five minutes. Can they complete the task in one sitting. Is the page clear. Are there too many fields. Do they know what happens next.

If the experience looks crowded or the flow feels clumsy, users read that as complexity, even if the underlying process is short and well designed. Once that perception sets in, behaviour changes. Managers default to email. Local admin support steps in. Manual work creeps back.

The result is important. A system can be technically sound and still feel hard to use. That is often where complexity gets “created” in the minds of the business.


Platform Breadth Is Not the Same Thing as Complexity Creep

SAP also gets criticised for being a platform that keeps expanding. There is always another module, another capability, another integration opportunity. Some clients see that as a sign they will never reach a stable end state.

That concern is understandable, but it often mixes up breadth with poor sequencing.

A broad platform is not the problem. Reactive buying is the problem. If organisations add capability without a clear business case, no owner, and no adoption plan, they create complexity by accretion. That can happen in SAP, and it can happen anywhere else.

The right test is simple. Is each addition tied to a business outcome and a realistic run model. If the answer is no, the issue is portfolio discipline, not SAP complexity.


Cultural Memory Matters More Than Teams Admit

There is also a cultural side to this. Many organisations carry a collective memory of SAP as heavy, expensive, and hard to change. Sometimes that comes from direct experience. Sometimes it comes from advisors, previous vendors, or stories that have circulated for years.

This matters because the SAP complexity debate is rarely just technical. It is shaped by trust, reputation, and old market narratives.

You can walk into a room with a solid solution and still spend half the meeting dealing with assumptions formed long before the current requirement existed. If you ignore that, the discussion becomes defensive and unproductive. If you address it directly, with facts and examples, the conversation becomes much more commercial and much more honest.


So, Is SAP Complexity Real?

Yes, SAP is a powerful enterprise platform. It can support large organisations, complex process models, and significant regulatory and control requirements. That capability comes with decisions. It is not a lightweight tool, and it should not be sold as one.

But that does not mean “heavy to run” is the default outcome.

In most programmes, the pain people describe as SAP complexity is actually the result of weak governance, unclear ownership, poor scope control, and fragmented process design. SAP exposes those gaps quickly because it sits at the centre of the operation. It does not create them on its own.

That is the point many teams miss.


What To Test Before You Label SAP “Too Complex”

If SAP complexity is the objection, the best next step is not a brand debate. It is a design and operating model conversation.

Teams should test their assumptions properly. They should be clear on how much process variation they are willing to accept, who will own standards after go live, what the BAU run model looks like for their size, and how they will manage changes without creating exception creep. They should also be honest about user experience, because perceived complexity often kills adoption long before architecture becomes the issue.

Most importantly, they should ask if they are assessing current SAP products based on current product reality, or on stories from a different era.

That one question usually changes the tone in the room.


Final Thought

The real choice is rarely SAP versus simple.

The real choice is structured complexity versus unmanaged complexity.

You can choose a smaller platform and still end up with high BAU overhead if governance is poor. You can choose SAP and run it cleanly if ownership, standards, and change control are tight.

That is the conversation worth having.


What to do next

If SAP complexity is coming up in your organisation, the next step is not to debate brand names in a steering meeting. It is to get specific about where the complexity is actually sitting.

Is it the platform, or is it governance, ownership, integration design, or user experience?                                                                                               

That is a much better conversation, and it usually leads to a better decision.
