High-yield GPM-b review for key rules, traps, decision cues, formulas, and final-week reminders.
Use this as your last-mile GPM-b™ review. Pair it with the Syllabus for the study blocks and Practice for speed.
For official source context, use Resources.
When the choices look close, stronger GPM-b answers usually follow this order:
| Lens | Ask first | Evidence or artifact to expect |
|---|---|---|
| People | who gains, who carries harm, and who must adapt? | workforce, community, health, safety, or inclusion indicators |
| Planet | what lifecycle burden changes? | energy, emissions, waste, resource, or biodiversity evidence |
| Prosperity | what value or cost effect is real over time? | financial case, resilience, and longer-term operating view |
| Product | what is being delivered and what footprint comes with it? | design choices, material choices, and use-phase effects |
| Process | how is the work performed and governed? | procurement rules, controls, reporting cadence, and audits |
| If the question is really about… | Better move | Weak move |
|---|---|---|
| whether an impact matters enough to act on | test significance to both stakeholders and organizational decisions | treat every impact as equally important |
| conflicting stakeholder views | surface the trade-off and make criteria explicit | pick the loudest voice without a rationale |
| narrow local optimization | widen the lens to lifecycle and downstream consequences | shift harm to suppliers, operations, or disposal |
| “good intentions” without metrics | demand a baseline, target, owner, and reporting method | accept a sustainability claim on wording alone |
An objective is credible only when it has:
| Phase | What stronger answers do | What weaker answers do |
|---|---|---|
| Initiate | embed sustainability in the business case and charter | keep it as a side note or PR statement |
| Plan | turn impacts into scope, procurement, quality, risk, and KPI rules | leave sustainability outside the working plans |
| Execute | collect evidence and correct deviations early | wait until reporting time to discover drift |
| Monitor and control | run change control with an impact lens | approve changes without testing sustainability consequences |
| Close | verify acceptance evidence and operational sustainment | declare success because the project delivered outputs |
| Procurement question | Better evidence | Weak pattern |
|---|---|---|
| does the supplier actually meet the claimed standard? | auditable criteria, reporting, certifications where relevant, and contract language | marketing claims with no measurable proof |
| are harms shifted outside the project boundary? | lifecycle and supply-chain view | only checking on-site effects |
| is performance sustainable after handoff? | operating KPIs, maintenance, usage, and disposal plan | assuming acceptance ends the obligation |
| Prompt | Why it matters |
|---|---|
| What metric proves this claim? | separates aspiration from evidence |
| Who owns the measurement and cadence? | makes the claim governable |
| What lifecycle stage is being ignored? | catches upstream or downstream harm shifting |
| What would make an auditor disagree? | stress-tests the claim before external scrutiny |
| Term | Quick meaning |
|---|---|
| Sustainability | meeting present needs without undermining future capacity |
| Triple bottom line | people, planet, and prosperity considered together |
| ESG | environmental, social, and governance reporting/risk lens |
| Materiality | importance strong enough to change decisions |
| P5 | people, planet, prosperity, product, and process impact structure |
Spend most of your final review on Sustainable Methods because it is the larger domain. Then test whether you can apply those methods in delivery scenarios, especially initiation and planning choices, execution evidence, monitoring controls, transition responsibilities, and closeout claims.
