Why project-level evidence matters now
Your disclosures are only as good as the projects behind them.
Most organizations know their sustainability commitments on paper. Fewer can say, with numbers, what share of their projects apply them. CSRD, ISSB and assurance providers are moving from "do you have a policy" to "show us where it is applied", and for a project-based organization that evidence lives in charters, gate reviews, procurement files and supplier audits.
PSM3™ produces that number, criterion by criterion, and the roadmap to raise it. The result is a measure that a board can read, an auditor can test, and a PMO can act on.
Five questions PSM3™ answers
Is a sustainability impact assessment part of project authorization, or optional?
Can the projects behind your sustainability report show their own evidence?
Would an auditor accept the portfolio data you hold today?
Do the same expectations reach your Tier 1 suppliers, and are they checked?
Do project leaders have governance tools for sustainability, or only guidance?
What PSM3™ assesses
52 impact elements. Five lenses. Three views.
PSM3™ is built on the PMI GPM P5 Standard for Sustainability in Project Management, Version 4.0, which organizes sustainability impact into 52 elements across People, Planet and Prosperity and examines each through the Product perspective (Lifespan and Servicing lenses) and the Process perspective (Efficiency, Effectiveness and Fairness lenses). Every element is crosswalked to the UN SDGs, GRI, TCFD and ISSB IFRS S1 and S2, so a PSM3™ finding traces to a disclosure standard. PSM3™ adds GPM's delivery-practice criteria, drawn from the standard's implementation and governance chapter, and scores every criterion from three views: your own organization, your supply chain, and what you disclose to external stakeholders. Elements that do not apply to your organization are flagged and excluded, so the score reflects your context.
24
People
Labor practices and decent work, society and customers, human rights, ethical behavior. Includes social regeneration, talent and sustainable procurement.
18
Planet
Transport, energy and emissions, land, air and water, consumption. Includes ecological regeneration and contamination.
10
Prosperity
Project feasibility, adaptive governance (materiality, optionality, resilience), market and economic stimulation, ESG disclosure.
Ch. 7
Practice
GPM's delivery-practice criteria: PMO governance and oversight, project selection and portfolio prioritization, vendor analysis, status reporting, closure and transition, agile and hybrid delivery, and controls on AI use.
Version 4.0 of the standard treats governance as embedded rather than as a separate impact category. PSM3™ keeps it visible: the Practice criteria are what make PSM3™ an assessment of how an organization delivers change, and why it is used by PMOs as well as sustainability teams. They cover gated reviews with a required P5 Impact Analysis and Sustainability Management Plan, sponsor training, portfolio alignment to strategy, benefits realization, asset lifecycle costing and value management.
The six PSM3™ maturity levels
A 4 or a 5 has to be earned in the projects.
Levels 0 to 3 describe awareness, ad hoc practice, and a written policy with an accountable owner. Levels 4 and 5 are awarded only after GPM checks adoption. A policy applied in at least half of your projects earns a 4; nine in ten earns a 5. For the supply chain, a 4 requires audited Tier 1 suppliers and a 5 requires the whole chain. For disclosures, the same thresholds apply to the share of projects reported. This is why a PSM3™ report can be used with auditors.
0
Uncertain
No understanding of the criterion in the organization.
Moves you up: awareness and training.
1
Nonexistent
Staff are unaware or unsure whether the criterion is addressed.
Moves you up: a named owner and a first practice.
2
Provisional
Practice exists but is ad hoc; no formal policy or procedure.
Moves you up: a written policy with accountability.
3
Foundational
A written policy or procedure is in place with an accountable owner.
Moves you up: adoption in at least half of projects.
4
Essential
Applied in 50% or more of projects; Tier 1 suppliers hold and are audited on the policy.
Moves you up: adoption across 90% of projects and the full supply chain.
5
Principled
Applied in 90% or more of projects; the whole supply chain holds and is audited on the policy; disclosed for 90% of projects.
Sustained by: annual re-assessment.
The model assumes that if a criterion matters enough to your organization to keep, it should have a goal of at least 3. Anything below that is either a gap to close or a criterion to mark as not applicable.
How the assessment works
From discovery to roadmap.
2 to 3 hrs
Discovery session with a certified GPM assessor
~10 days
On site with at least two certified assessors
3 scores
Goal, perceived and validated level for every criterion, from three views
18 to 24 mo
Improvement roadmap, sequenced by quarter
Discovery. A two to three hour session sets the scope, the stakeholders to interview and the timing. You receive a tailored delivery plan.
Facilitated assessment. About ten assessor days on site, opening with a workshop that builds buy-in. For every criterion your leadership sets the target level and your teams state where they believe they are.
Validation. GPM reviews policies, procedures, project documents, supplier requirements and public reporting to assign the validated level for each criterion and view.
Gap analysis. Risks and blind spots are identified, including gaps and overlaps with your existing sustainability and annual reporting.
Recommendations and roadmap. A recommendation for every criterion below 5, and an 18 to 24 month implementation plan by quarter, with priorities and milestones.
Annual re-assessment. Repeat the assessment to show the trajectory to your board and refresh the roadmap.
What you receive
Three numbers for every criterion, and the distance between them.
The PSM3™ Outcome Report shows, for every criterion and view, the level your leadership set as the goal, the level your teams believe they are at, and the level GPM validated against evidence. The gap between the last two is your alignment gap: what leadership believes against what the evidence shows. The gap between the first and the last is your roadmap.
Category ratings for People, Planet, Prosperity and Practice, separate ratings for your supply chain and your disclosures, and criterion-level findings with the evidence reviewed are presented in a form that boards, investors and auditors can use. An appendix maps the findings to the ISO standards involved and, where you have one, to your own sustainability framework.
Repeat the assessment annually and the report shows your trajectory.

Who uses PSM3™
Built for the people who own delivery and the people who sign the report.
Chief Sustainability Officers
who need project-level evidence behind enterprise disclosures, and a measure of how far commitments reach into delivery.
PMO and portfolio leaders
who need a governance baseline, a prioritised improvement plan, and a number to report to the board each year.
Boards and investors
who want an independent, repeatable measure of whether capital projects apply the organization's stated commitments.
Teams preparing for CSRD, ISSB or assurance
who need to know what the projects can show before the auditors ask.
Evidence from the field
A national energy company's project delivery division, assessed in consecutive years.
In the second year the division's Planet rating rose from 2.3 to 3.9 and its Practice rating from 3.0 to 3.4 on the 0 to 5 scale. Supply chain ratings trailed the organization's own by roughly one level in Planet and Prosperity, which set the priorities for the following roadmap.
The engagement covered the full instrument from all three views, with on-site interviews across delivery, HSE, procurement and sustainability functions and a review of more than a hundred policies, standards and project documents. Client details are withheld by agreement.
Organizational rating, year two against year one
People
4.1 from 4.0
Planet
3.9 from 2.3
Prosperity
4.5 from 4.8
Practice
3.4 from 3.0
The instrument was revised between the two years, so the figures show direction rather than a strict like-for-like comparison.
How PSM3™ relates to other assessments
PSM3™, OSEM, P3M3 and corporate ESG ratings.
| Assessment | What it measures | Scope | Use it when |
|---|---|---|---|
| PSM3™ | Sustainability maturity and delivery capability, scored with evidence on the P5 Standard, Version 4.0 | Portfolios, programs and projects, plus supply chain and disclosures | You need to show what the projects behind your commitments actually apply |
| OSEM | Sustainability excellence across the enterprise | The whole organization | You want an enterprise-wide baseline rather than a delivery-focused one |
| P3M3 | Portfolio, programme and project delivery capability, without a sustainability lens | Delivery processes | You want a process maturity view only. PSM3™ and P3M3 are different models and are complementary. |
| Corporate ESG ratings | Quality and completeness of disclosures | Published reporting | You need a market signal. PSM3™ tests whether the projects behind the disclosures apply them. |

Questions we are asked
Before you request an assessment.
How long does a PSM3™ assessment take?
Discovery takes two to three hours. On-site facilitation and interviews take about ten assessor days, depending on the size of the organization and the number of business units in scope. Validation, the report and the roadmap follow within a few weeks.
Who needs to be involved?
A sponsor, the PMO or portfolio lead, and the people who own the criteria in practice: delivery, procurement, HSE, HR, finance and sustainability reporting. Discovery produces the interview list.
What do we need to prepare?
Access to the policies, procedures, project documents and supplier requirements that support each criterion. Validation is only as strong as the evidence made available, and the report states where evidence could not be reviewed.
Can the report be used with auditors and assurance providers?
Yes. Levels 4 and 5 are awarded on adoption thresholds checked against project records, and each criterion lists the evidence reviewed and the standards it draws on.
How often should we repeat it?
Annually. Moving a criterion from 3 to 4 or 5 usually takes a year or more, because it requires adoption across projects or the supply chain. A yearly re-assessment shows the trajectory and refreshes the roadmap.
Does it work for a single division or business unit?
Yes. Most assessments are scoped to a project delivery organization, treated as its own entity with its own supply chain and reporting obligations.
How does PSM3™ relate to the P5 Standard and GPM certifications?
The impact criteria are the elements of the P5 Standard, Version 4.0, so an organization that adopts P5 will recognise every line, and each finding carries the standard's crosswalk to the SDGs, GRI, TCFD and ISSB. Assessments are conducted by certified GPM assessors, and GPM-certified professionals inside your organization can own the roadmap.
Is there a lighter option?
Start with the free self-check above. A facilitated assessment without full validation can be scoped for organizations that want an internal baseline before a validated one.
