LTP10 common mistakes
LTP10 · Understand the traps and how to avoid them.
Answering terminology questions from everyday usage instead of the exam's defined meaning, e.g., treating 'risk' as only bad outcomes or 'project' as any ongoing task.
Candidates rely on workplace vocabulary where words carry looser or different senses than the formal definitions tested, so the intuitively appealing option is often the distractor.
What to do instead
Build a one-page glossary of core terms with the exam definition, one contrast word, and one counterexample. Before selecting an answer, restate the stem using the formal definition and eliminate options that conflict with it.
Choosing an answer because it describes a generally good practice rather than the practice the question asks for (e.g., picking 'communicate more' when the stem asks for the next step in a defined process).
Good-sounding options feel safe, and under time pressure candidates match on tone rather than on the specific decision rule or sequence being tested.
What to do instead
Highlight the operative words in the stem (first, next, best, primary, except) and ask which option the stem's rule or stage actually requires. Discard options that are merely desirable but not responsive.
Skipping scope decomposition and jumping straight to a schedule, producing a plan with activities that cannot be traced to any deliverable or acceptance criterion.
Schedule thinking is more familiar and concrete than scope decomposition, and stakeholders often push for dates early, so the work breakdown is compressed or omitted.
What to do instead
Draft the deliverable hierarchy first and attach a measurable acceptance criterion to each lowest-level item. Only create activities that map to a lowest-level deliverable, and verify coverage by checking each requirement appears exactly once.
Estimating with a single-point number and no stated basis, then carrying that number into commitments without recording assumptions or confidence.
Point estimates are quick and socially easier to defend than ranges, and organizations reward confident-sounding plans over honest uncertainty.
What to do instead
Produce three-point estimates or ranges with the basis of estimate written down (analogy, parametric, historical data) and list the assumptions that would change the number. Present ranges to sponsors and convert to commitments only after reserves are agreed.
Treating stakeholder engagement as a one-time communication event at kickoff rather than an ongoing, planned activity with distinct stakeholder groups.
Kickoff meetings create a false sense of alignment, and teams default to broadcasting the same message to everyone instead of segmenting by influence and interest.
What to do instead
Maintain a stakeholder register with influence, interest, and preferred channel, and a communication plan specifying message, audience, frequency, and owner. Review the register at each status cycle and after any significant change.
Escalating a conflict or issue immediately to the sponsor instead of first attempting direct resolution at the lowest appropriate level.
Escalation feels decisive and low-risk to the candidate, and many workplaces reward rapid upward referral, so it looks like the 'professional' answer.
What to do instead
Apply a resolution ladder: address directly, then facilitate between parties, then use formal procedures, then escalate. In scenario questions, choose the earliest rung that can realistically resolve the issue and reserve escalation for when authority or policy is genuinely required.
Monitoring only schedule and cost while ignoring scope, quality, and benefit indicators, so variance in delivered value goes undetected until late.
Earned value and milestone tracking are the most visible metrics, and status reports tend to inherit whatever the template already measures.
What to do instead
Define a balanced measurement set covering scope change, quality thresholds, benefit realization, and stakeholder satisfaction alongside time and cost. For each metric, state the threshold that triggers action and the owner, and review all of them on a fixed cadence.
Reporting raw progress percentages without a baseline, so '80 percent complete' cannot be verified or compared across periods.
Percentages are easy to produce and easy to inflate, and without an approved baseline there is no reference point to challenge them.
What to do instead
Approve and version a baseline before execution and express progress against it using objective completion criteria. Where possible, measure completed deliverables rather than effort spent, and require evidence for any claimed percentage.
Selecting a solution to a problem before confirming the root cause, typically by acting on the first plausible explanation.
Time pressure and the availability of an obvious fix encourage jumping to remedy, and early hypotheses anchor subsequent interpretation of evidence.
What to do instead
Use a structured cause analysis (five whys, cause-and-effect diagram, or fault tree) and state the evidence supporting the chosen cause. Before implementing, write the predicted outcome and how it will be verified, then confirm the problem actually resolves.
Making a decision without documenting the criteria, alternatives considered, or the owner, so the decision is reopened repeatedly by different stakeholders.
Decisions are often made in conversation and never recorded, and unclear decision rights invite re-litigation by anyone who disagrees.
What to do instead
Use a short decision record: decision, owner, date, criteria, alternatives considered, and consequences accepted. Confirm who holds decision authority before the discussion, and publish the record so later challenges reference it rather than restarting the debate.
