What CMMi for Acquisition is
CMMI (Capability Maturity Model Integration), administered by ISACA, is a globally recognised model for improving how an organisation performs its work and for measuring the maturity of those processes. The Acquisition view — CMMi-ACQ — applies the model to organisations that obtain products and services from suppliers rather than build them in-house. It strengthens the processes around planning acquisitions, selecting and managing suppliers, and verifying that what is delivered meets requirements. (In current CMMI, this domain is commonly framed as Supplier Management — the terminology has evolved, but the focus on disciplined acquisition is unchanged.)
The maturity levels
CMMI uses the same five maturity levels across all of its views:
- Level 1 — Initial: acquisition is ad hoc and unpredictable
- Level 2 — Managed: acquisition processes are planned, performed and measured
- Level 3 — Defined: processes are standardised across the organisation
- Level 4 — Quantitatively Managed: performance is controlled using quantitative techniques
- Level 5 — Optimizing: the organisation continually improves performance
For organisations that depend heavily on suppliers, a higher maturity level means fewer surprises, better value and more reliable delivery from the supply base.
Appraisal, not certification
As with the rest of the model, maturity is confirmed through an appraisal, not a certification. The formal method is SCAMPI, conducted by an appraisal team led by a certified Lead Appraiser, and the result is typically valid for three years.
How ABS supports CMMi-ACQ
ABS has supported organisations with CMMi since 1991, and our Certified Lead Appraisers are among the most experienced worldwide — certified lead assessors recognised by the CMMI Institute. Our consultants bring a minimum of 8–10 years’ hands-on experience implementing CMMI.
We support organisations end to end as they mature their acquisition and supplier-management processes: gap analysis and current-state assessment, CMMi overview training, a process-improvement strategy and roadmap, defining and documenting acquisition processes, establishing a measurement framework, software quality assurance (SQA) support, SCAMPI facilitation, and appraisals conducted by our Lead Appraisers.
It suits organisations with significant procurement or outsourcing — including manufacturing supply chains and enterprises that outsource development. It complements CMMi for Development and CMMi for Services; see the full CMMi & Process category for related work.
Common questions
What does CMMi for Acquisition cover?
It applies the CMMI model to organisations that obtain products and services from suppliers rather than build them in-house — strengthening how they plan acquisitions, select and manage suppliers, and verify what is delivered. Current CMMI often calls this domain Supplier Management.
How does it differ from CMMi for Development and Services?
All three share the same five-level maturity scale and appraisal approach. Development targets building products and systems, Services targets delivering services, and Acquisition targets buying and managing what suppliers provide.
