FROM ENQUIRY TO ASSESSMENT
How the enquiry works
01
Describe your requirement
Share your activities, sites and the scheme or buyer requirement you need to meet.
02
Confirm the appropriate route
Check the scheme's authorised assessment or certification route and service availability before proceeding.
03
Agree the scope and quote
Request written confirmation of deliverables, responsible bodies, fees and any travel or assessment costs.
04
Prepare the evidence
Use the service-specific checklist below to identify existing records and gaps for review.
05
Follow the scheme's assessment
The responsible scheme body determines assessment and any certification or rating. An enquiry does not guarantee an outcome.
STARTING YOUR APPLICATION
Initial business documents
These establish who is applying and the proposed business scope. They are the starting point; the service-specific review or assessment can require additional operational evidence.
Business registration
Udyam, incorporation certificate or shop licence.
Letterhead or visiting card
Your business name and contact details.
One business invoice
A recent sales or purchase invoice.
Your business scope
What you do, in one or two clear lines.
Prepare for CMMI Level 5
Use these process maturity appraisal: optimizing checks to organise your preparation. For each item, identify the responsible person, the procedure used and a recent record showing what happens in practice.
- All level 3 practices in place
- Quantitative management of process performance
- Statistical analysis of project data
- Root cause analysis and continuous improvement
- High maturity appraisal by an authorised lead appraiser
Make your evidence match your scope
- Describe the actual activities and locations to be reviewed, including outsourced work and responsibilities retained by your business.
- Choose current examples from your own operation. Record the date, responsible person and outcome so the reviewer can connect the evidence to your stated scope.
- Identify missing records or unfinished actions before assessment. A policy or blank template alone does not show how a process operates.
- Ask which records apply to your selected service and scope. This preparation checklist is not an exhaustive assessment or a promise of certification.
CMMI appraisals are conducted only by CMMI Institute authorised partners. This page is an enquiry page; we do not issue CMMI ratings under ISAO.
BEFORE YOU COMMIT
Confirm these details in writing before payment
Use the published price alongside the agreed scope and service terms when deciding whether the offering meets your requirement.
- Scope and deliverable: the applicable standard or scheme, edition, activities, sites and exclusions, and exactly what document or support the service provides.
- Issuing or assessment body: its name and role. If accredited certification is required, confirm the accreditation body and that the relevant standard and scope are covered.
- Buyer acceptance: share the actual tender or customer clause and confirm that the proposed route meets it. A certificate title alone does not establish acceptance.
- Assessment arrangements: required documents, audit or review stages, remote or on-site work, travel, readiness requirements and expected timing.
- Fees and exclusions: the selected service price, what is included, and any separate implementation, testing, site visit, travel or statutory registration costs.
- Ongoing obligations: applicable surveillance, renewal or reassessment, their fees, and how changes to your activities or locations should be reported.
Certification and accreditation have different roles. See ISO's guidance on choosing a certification body.
