📏 Estimate Types & Accuracy Ranges, Know All Four
| Estimate Type | Accuracy Range | When Used | How It's Done | Key Exam Notes |
|---|---|---|---|---|
| Rough Order of Magnitude (ROM) | −25% to +75% | Initiating / very early project, before detailed planning | Expert judgment, analogous data from past projects, high-level assumptions | Also called a "ballpark estimate." Wide range reflects high uncertainty. Used to get initial approval or funding. NOT suitable for budgeting. If a question says "early estimate" or "feasibility" → ROM. |
| Budget Estimate | −10% to +25% | Early Planning, after some scope definition but before detailed WBS | Analogous or parametric estimating using partial scope information | More refined than ROM. Used to establish initial budget authorization. Still significant uncertainty. Sometimes called a "preliminary estimate." Used when sponsor needs a budget range to proceed. |
| Definitive Estimate | −5% to +10% | Late Planning, after detailed WBS and resource plans are complete | Bottom-up estimating from detailed work packages. Most accurate method. | Most accurate estimate type. Requires the most time and effort to produce. Used for final budget approval and cost baseline. If a question asks for the "most accurate estimate" → Definitive using Bottom-Up. |
| Order of Magnitude | −50% to +100% | Pre-project / concept phase, before the project is formally authorized | Very rough judgment based on similar projects or industry benchmarks | Even less precise than ROM. Used for portfolio-level decisions, "should we even consider this project?" Sometimes used interchangeably with ROM on the exam, but technically wider range. Context determines which applies. |
📊 Earned Value Management (EVM), Full Reference
| Term (Abbr) | What It Means | Formula | Interpretation |
|---|---|---|---|
| Budget at Completion (BAC) | The original approved total budget for the project. | No formula, it's the baseline | Your starting budget number. Never changes unless a baseline change is approved. |
| Planned Value (PV) | The budgeted cost of work scheduled to be done by now. | PV = Planned % Complete × BAC | What you PLANNED to have done by this point, in dollars. |
| Earned Value (EV) | The budgeted cost of work actually performed. | EV = Actual % Complete × BAC | What you actually ACCOMPLISHED, valued at the budgeted rate. |
| Actual Cost (AC) | The actual cost incurred for work performed. | No formula, actual spend | What you actually SPENT. No formula, it's measured directly. |
| Cost Variance (CV) | Difference between earned and actual cost. | CV = EV − AC | Positive = Under budget ✓ · Negative = Over budget ✗ |
| Schedule Variance (SV) | Difference between earned value and planned value. | SV = EV − PV | Positive = Ahead of schedule ✓ · Negative = Behind schedule ✗ |
| Cost Performance Index (CPI) | Rate of cost efficiency, how much value per dollar spent. | CPI = EV ÷ AC | ≥ 1.0 = Under budget ✓ · < 1.0 = Over budget ✗. CPI = 0.8 means you get $0.80 of work per $1.00 spent. |
| Schedule Performance Index (SPI) | Rate of schedule efficiency, how much work done vs. planned. | SPI = EV ÷ PV | ≥ 1.0 = Ahead of schedule ✓ · < 1.0 = Behind schedule ✗ |
| Estimate at Completion (EAC) | Forecasted total cost at project completion based on current performance. | EAC = BAC ÷ CPI (most common) EAC = AC + ETC EAC = AC + (BAC − EV) EAC = AC + [(BAC − EV) ÷ (CPI × SPI)] | Use BAC/CPI when current inefficiency is expected to continue. Use AC+(BAC−EV) when remaining work will be done at planned rate. |
| Estimate to Complete (ETC) | Expected cost to finish remaining project work. | ETC = EAC − AC | How much more money is needed from today to finish the project. |
| Variance at Completion (VAC) | Expected over/under budget at project end. | VAC = BAC − EAC | Positive = Under budget at completion ✓ · Negative = Over budget at completion ✗ |
| To-Complete Performance Index (TCPI) | The efficiency that must be achieved on remaining work to meet a financial goal. | TCPI = (BAC − EV) ÷ (BAC − AC) to meet BAC TCPI = (BAC − EV) ÷ (EAC − AC) to meet EAC | TCPI < 1.0 = Easier than planned ✓ · TCPI > 1.0 = Must be MORE efficient than planned ✗ |
📐 Other Key Formulas

📐 The 12 Project Management Principles (PMBOK 7)
🎯 The 8 Performance Domains (PMBOK 7)
| Type | Full Name | Risk | When to Use | Key Exam Notes |
|---|---|---|---|---|
| FFP | Firm Fixed Price | Seller | Well-defined stable scope. Most common type. | Seller absorbs cost overruns. Buyer knows total cost upfront. Most preferred by buyers. Seller motivated to be efficient. |
| FPIF | Fixed Price Incentive Fee | Mostly Seller | Well-defined scope + want to incentivize performance. Has target cost, target fee, ceiling price, share ratio. | Above the PTA (Point of Total Assumption), seller bears 100% of overruns. PTA = ((Ceiling − Target Price) ÷ Buyer Share Ratio) + Target Cost. |
| FP-EPA | Fixed Price w/ Economic Price Adjustment | Mostly Seller | Long-term contracts where inflation could affect costs. | Price adjustments pre-defined based on index (CPI, labor rates). Protects seller from economic changes while giving buyer cost predictability. |
| CPFF | Cost Plus Fixed Fee | Buyer | Scope not well-defined. Seller reimbursed all costs plus a fixed fee that doesn't change with performance. | Seller has little incentive to control costs, gets paid regardless. Fixed fee only changes if scope changes. Buyer takes full cost risk. |
| CPPC | Cost Plus % of Cost | Buyer (ALL risk) | Rarely used. Seller reimbursed for costs plus a % of actual costs as fee. | Seller is incentivized to INCREASE costs (higher costs = higher fee). WORST contract type for the buyer. Illegal in US government contracts. Almost always the wrong answer. |
| CPIF | Cost Plus Incentive Fee | Mostly Buyer | Undefined scope where you want to incentivize cost efficiency. Both parties share overruns/savings via share ratio. | Seller beats target cost → both share savings (seller gets higher fee). Seller exceeds → both share overrun (seller gets lower fee). Fee has min/max bounds. Better than CPFF for buyer. |
| T&M | Time and Material | Shared | Scope undefined. Short-term work, staff augmentation, or when needing to start immediately. | Fixed rate per hour + reimbursed materials. No incentive to finish quickly. Usually has a "not-to-exceed" clause. Common for consulting. Hybrid of FP and CR. |
| Factor | Predictive | Iterative / Incremental | Adaptive (Agile) |
|---|---|---|---|
| Requirements | Fixed upfront | Partially defined, refined over time | Emergent, evolve continuously |
| Deliverables | One final delivery | Multiple refined versions | Frequent small working deliveries |
| Change | Tightly controlled via CCB | Expected, managed per iteration | Welcomed, prioritized by Product Owner |
| Customer Involvement | At start and end | At iteration boundaries | Continuous throughout the project |
| Risk Exposure | High, problems discovered late | Moderate, discovered per iteration | Low, discovered early via rapid feedback |
| Documentation | Heavy and formal | Moderate | Lightweight, just enough |
| Team Structure | Specialized roles, PM directs | Cross-functional teams | Self-organizing, cross-functional |
Everything below is reference material, built to be jumped around and searched, not read start to finish in page order. Here's the order that actually works, do Step 1 first, then keep the rest as a lookup you return to, and circle back to Step 1 repeatedly as exam day gets close.
The night before and the morning of your exam: skip everything else and re-read Step 1. That's the section people who've failed keep saying, in hindsight, they underweighted.
The exam is scored against the Exam Content Outline (ECO), not the PMBOK Guide. The ECO groups everything into three domains, and the 2026 update reweights them dramatically. The single biggest change: Business Environment tripled from 8% to 26%, absorbing risk, governance, change control, and impediments from the other two domains. If you studied the old split, your instinct for where to spend time is now wrong. Match your study hours to these weights.
| Domain | 2021 ECO | 2026 ECO | Shift | ~Scored Qs |
|---|---|---|---|---|
| People | 42% | 33% | −9 | ~56 |
| Process | 50% | 41% | −9 | ~70 |
| Business Environment | 8% | 26% | +18 | ~44 |
Roughly 170 scored questions total. Business Environment goes from about 14 questions to about 44, so it is no longer a domain you can skim.
The 8th Edition refines the 7th Edition's twelve principles into six, merging some and migrating two (Tailoring and Risk) into their own dedicated sections. These are plain-language summaries; verify exact wording against the official guide.
Performance domains are the interactive areas of project work that, taken together, deliver outcomes. Quality now lives inside Scope; Communications now lives inside Stakeholders; Procurement is reframed as Resources/sourcing.
Focus Areas are the 8th Edition's answer to the old Process Groups: they describe when work happens across a project's life cycle, not a fixed list of processes. The 38 named processes (in the grid below) live inside the 7 performance domains and naturally fall into one or more of these five areas as the project moves forward.
The 8th Edition frames the six principles as three working dimensions of mindset, a useful lens for exam scenario questions that test attitude as much as mechanics.
Most scenario questions are really testing attitude. The "PMI mindset" is a specific default posture, and when two answers both look reasonable, the one that fits this posture almost always wins. These are ordered by how many questions they decide, learn the top ones cold first. It is a lens, not memorization: read every situation as a servant leader who is proactive, collaborative, and value-driven.
The People domain is 33% of the exam, and a handful of named models keep deciding its questions. None of these changed in the 8th Edition. Learn the model, then learn the cue that tells you a question is testing it.
Teams move through predictable stages, and the PM's leadership style should shift with each one. The exam loves giving you a team behavior and asking for the matching response.
Classify each stakeholder's current engagement, compare against the level you need, and close the gap deliberately: Unaware → Resistant → Neutral → Supportive → Leading. Exam cue: when a question gives you a stakeholder's attitude and asks what to do, the answer usually starts with assessing current versus desired engagement, then engaging directly to move them one step, not from Resistant straight to Leading.
AI questions are new to the 2026 exam, and firsthand reports agree they are mostly common sense plus mindset. You need three things: the vocabulary ladder, the three levels of use, and the governing principle.
The 8th Edition gives tailoring its own dedicated section, and the exam treats it as a default assumption: no process, template, or approach is applied just because it exists. Three things get tailored, and a handful of factors drive how.
Earned value management is math, not edition-specific narrative, so none of this changes in the 8th Edition. It is repeated here so 8th-edition study is self-contained; full detail lives in the 6th/7th tab's Calculations panel.
| Formula | Equation | Meaning |
|---|---|---|
| Cost Variance (CV) | EV − AC | Negative = over budget |
| Schedule Variance (SV) | EV − PV | Negative = behind schedule |
| Cost Performance Index (CPI) | EV ÷ AC | Below 1.0 = inefficient spending |
| Schedule Performance Index (SPI) | EV ÷ PV | Below 1.0 = behind schedule |
| Estimate at Completion (EAC) | BAC ÷ CPI | Forecast total cost at current efficiency |
| Estimate to Complete (ETC) | EAC − AC | Forecast remaining cost |
| To-Complete Performance Index (TCPI) | (BAC − EV) ÷ (BAC − AC) | Efficiency required on remaining work to hit BAC |
| Estimate type | Typical range | When |
|---|---|---|
| Rough Order of Magnitude (ROM) | −25% to +75% | Initiating, very early screening |
| Budget estimate | −10% to +25% | Early planning |
| Definitive estimate | −5% to +10% | Late planning, well-understood work |
The pattern to remember: ranges narrow as knowledge grows. A question offering false precision early ("give a definitive estimate at kickoff") is testing whether you know these bands.
Most people who fail the PMP know the material. They lose on how the question is worded. These are decision rules for the moments where two answers both look right. Drill them until they're automatic, because you will not have time to reason them out fresh 180 times on exam day.
PMI buries the deciding detail in the verb tense of the stem. Before you read the answers, find the verb and ask: has this happened yet? That one distinction often decides the whole question.
It extends past risk vs issue: "CCB has approved the change" (done) means implement it, don't re-analyze. "The team is blocked" (now) means act to remove the impediment. "A regulation will take effect next quarter" (future) means plan and assess, don't react yet.
Answer the verb, not the mood. "The team is frustrated," "urgent!" and so on: the emotional tone is bait. The tense tells you what's actually being asked. Getting the topic right but the timing wrong still loses the question.
So many questions come down to: should the PM do something, or go learn more first? Both options sit right there looking correct. The tiebreaker:
People blow EVM not on the formulas but on the plus/minus direction. One rule covers all four metrics:
The one thing that sounds like an exception but isn't: "under budget." A high CPI (say 1.2) is good, and you describe that good situation as "under budget." So it isn't a reversal, it's just high-CPI wearing a costume. The only good "under" is "under budget."
Formulas, EV always first: cost pairs with AC, schedule pairs with PV. Variance subtracts, index divides. CV = EV − AC · SV = EV − PV · CPI = EV ÷ AC · SPI = EV ÷ PV.
Elimination trick: C = Cost = money (AC), S = Schedule = time (PV). If a question asks about SV (schedule) but an answer talks about budget, that answer mixed the wrong variable. Strike it on sight. Many EVM distractors are wrong simply because they answer the wrong dimension.
These are exam-technique heuristics, not PMI doctrine. They're pattern shortcuts for the pressure of exam day; the study panels above are where the actual knowledge lives.
The Gauntlet tests you. This section teaches. Each scenario below is worked out loud, step by step, so you can see the reasoning that separates the best answer from the three that look right. Read these before you drill the Gauntlet, then do the Gauntlet to see if the thinking stuck. The goal is to make this reasoning automatic.

These chart types are universal project management tools, not specific to one edition, so nothing here changes with the transition. In 8th edition they live under the unified Models, Methods & Artifacts reference instead of being tied to one named process, but the charts themselves and what they're for are identical. Each card has a small example so you can recognize the shape on sight.
Each card shows its 6th-edition equivalent where one exists, an original purpose summary, and key practices in place of a fixed ITTO table, since 8th edition processes are written as adaptable practices rather than rigid input/tool/output recipes.

Grouped by the 7 performance domains, the 8th Edition's own structure.
Every document PMI expects you to recognize, filed by where it first enters the project. These are edition-independent: the 8th Edition catalogs them once in its unified Inputs & Outputs reference instead of repeating them per process, but what each one holds is unchanged. Click any row to reveal what it contains, or quiz yourself by guessing first. The standalone visual version has the phase-spine view and print mode.
The 2026 exam opens with a case-study section: one scenario, several linked questions. On the real thing the questions from two cases can interleave (a Case 1 question, then Case 2, then back to Case 1), so practice anchoring yourself to the scenario before each answer. Read the whole case first. Below is one original case with three linked questions in that style, each with full explanations.
Original scenario questions written in the real exam's nastiest style: every option is defensible, and only one is best. Each targets an 8th Edition concept, and every wrong answer comes with the reason it loses, because knowing why the almost-right answer is wrong is the skill the exam actually tests. These are practice drills built from the 8th Edition framework and the exam mindset, not recycled or leaked exam content, so treat them as training, not prediction.
