A CMMI appraisal gives you the maturity level tenders demand
A tender asks for Maturity Level 3 or better and procurement checks the rating before accepting a bid. A certified lead appraiser rates how consistently you run requirements, estimation, configuration management, verification and project monitoring on real projects.
- !A government or defence software tender lists Maturity Level 3 as a pass or fail criterion.
- !A prime contractor is flowing down process maturity requirements to its development subcontractors.
- !Delivery estimates keep slipping and nobody can say which projects follow which process.
- !An offshore development centre is competing on process credibility against already-appraised rivals.
- !Your rating expires within twelve months and bids submitted after that date will be rejected.
- !Client audits keep finding requirements traceability that stops at the design document.
A model of engineering and management practices, and a formal appraisal against it. CMMI looks at how projects are actually run - requirements, planning, estimation, configuration control, verification, supplier management - and awards a maturity level based on evidence from sampled projects.
A benchmark appraisal is conducted by a certified lead appraiser under the CMMI model and published in the appraisal results directory. It is a rating, not a management-system certificate.
A benchmark appraisal rating is valid for three years and is publicly listed. There is no annual surveillance; you re-appraise before expiry to stay bid-eligible.
Software and systems development organisations, IT services firms, defence and aerospace suppliers, and offshore delivery centres bidding where a maturity level is specified.
Industries that require ISO 22000 Certification
CMMI is applicable across 2 of the 25 industries SIS covers. The pages below set out the specific reason it comes up in each one.
What CMMI Actually Requires
An organisation must understand the requirements for ISO 22000 certification to implement it effectively.
A process library covering the project lifecycle, tailored per project rather than photocopied, with the tailoring decisions recorded and approved before work starts.
Requirements captured, agreed with the customer, baselined and traceable through design, code and test, with a controlled route for handling change.
Estimates built from a documented basis and historical data, plans covering effort, schedule, resource and risk, and a record of what was re-planned and why.
Baselines under version control, change requests reviewed before they are applied, and build records that let you rebuild any released version from source.
Peer reviews and testing planned against the requirements, with defects logged, dispositioned and closed, and evidence that reviews happened on the projects being sampled.
Project data collected consistently - effort variance, defect density, review coverage - analysed at organisation level and fed back into the process assets.
How CMMI Appraisal Works
A clear, step-by-step process from your first call to a completed engagement.
Readiness Review & Scoping
The organisational unit, project sample and target maturity level are agreed with a certified lead appraiser, along with which practice areas fall inside the appraisal scope.
1–2 weeksProcess Implementation Period
A process written this quarter cannot evidence a project that finished last one. Practices have to run on live work, and two to four project cycles is the usual wait.
3–9 months typicallyReadiness Assessment & Evidence Mapping
Project artefacts are mapped to practice areas and gaps closed before the benchmark. A readiness pass is where weak traceability and missing peer review records surface.
4–8 weeksBenchmark Appraisal & Rating
The appraisal team reaches a rating and it is published with an expiry date. Nothing audits you in between, so the practices either hold on their own or quietly lapse.
1–2 weeks on site; rating valid 3 yearsIndustries That Need CMMI
Commonly taken alongside
Not Sure Which Certification You Need?
Three questions. The selector reads the same industry-to-standard mapping this whole site is built on, then shortlists what applies to you.
Which sector best describes your organisation?
Twelve months of evidence cannot be assembled in six
The appraisal itself is a fortnight. The twelve to eighteen months in front of it is where the money goes, and a tight project sample is the only lever on it.

More than a certificate — a testimony that you have raised the bar and built customer confidence.
Bids that pass screening
Where a maturity level sits in the eligibility criteria, an unappraised bidder is rejected at document check before anyone reads the technical proposal.
Fewer surprise overruns
Estimation built from historical data and disciplined re-planning replace optimism, and the difference shows up first in fixed-price margin and delivery penalties.
Traceability that holds
Requirements traceable through design, code and test mean change requests get priced properly and scope disputes with the client end with a document.
Compared on the same scale
Maturity levels are read the same way in every market, so an offshore delivery centre is compared on the same scale as the local supplier bidding beside it.
Repeatable delivery at scale
New teams and acquired units inherit a working process instead of inventing their own. That is what makes rapid growth survivable rather than chaotic.
Defects caught earlier
Planned peer reviews and verification move defect discovery earlier. A defect found at review costs a fraction of the same defect found after release.

Plan your appraisal around the bid deadline
Nine months before expiry is when organisations that bid regularly start re-appraisal. Later than that and you are choosing which tenders to sit out.
