How many Ariba consultants do we need for our project?​

"Can't we just hire one Ariba consultant to do everything?"
 

​​

I hear this question a lot.

​

On paper, it sounds efficient: one person implementing SLP, Risk, Sourcing, Buying, and Integration. One point of contact. One budget line. Simple.

​

In reality? It’s a high-risk decision.

​

Here’s why.

​

Each Ariba module is its own discipline.

​

SLP alone requires deep understanding of supplier onboarding processes, questionnaires, approvals, multi-step qualification processes, data models, and governance.
Risk adds external data providers (APIs required), risk exposure logic, risk control definition and monitoring workflows.
Sourcing is a different world — different event types, templates, optimization, award scenarios.
Buying involves catalogs, approval flows, ERP touchpoints, invoicing logic.
And Integration? That’s technical architecture, middleware, master data replication, and troubleshooting at system level. Rather different from process consulting.

​

To gain real implementation depth in just one module typically requires multiple full project cycles.

That means years — not weeks of training. Plus real-life hands-on experience.

Now multiply that by five.

​

True multi-module depth across the entire suite is extremely rare.

When someone claims to cover everything, what often happens is this: breadth replaces depth.

And depth is what protects your project from expensive rework.

​

There’s also a commercial reality many clients don’t see:

Consulting firms are driven by utilization.

​

• Training across many modules is expensive.

• A consultant skilled in one or two modules can already be fully booked.

• There is no strong business incentive to create five-module generalists when two-module specialists are sufficient to maximize billable capacity.

​

Consulting companies optimize for predictable delivery and full utilization — not for producing the broadest possible education per individual.

That’s not criticism. That’s economics.

​

If you want to reduce delivery risk on an Ariba program, the safer structure is:

​

• A strong solution architect
• Dedicated module specialists
• A true integration expert
• Clear workstream ownership

 

Trying to save cost by consolidating everything into one person often increases timeline, stress,

and downstream correction effort.

Specialization isn’t overengineering. It’s risk management.

​

If you’re planning an Ariba program, design your team structure as carefully as your system architecture.
