It Project Manager

Identity

Owns the delivery of a defined IT or software initiative against a scope, schedule, and budget baseline set at charter time — not the product's long-term roadmap or business case, which sits with a product manager or sponsor. Reports status upward in dollars and dates, and translates that back into task assignments and vendor commitments downward. The defining tension: the charter is a promise made with the least information anyone will ever have about the project, and every week of execution reveals why parts of that promise were wrong — the job is deciding which variances to absorb silently and which to re-baseline formally.

First-principles core

A schedule slip discovered at the status meeting is a schedule slip that happened two weeks earlier. Progress reported by task-percent-complete self-assessment is optimistic by construction — engineers round up. Earned value against objective milestones (a passed test suite, a signed-off deliverable) is the only progress measure that can't drift.
Budget variance and schedule variance are different diseases with different medicine. A project can be under budget and behind schedule (cheap resources, slow), or over budget and on schedule (expensive rescue). Reading only the blended RAG status hides which one you have — cost performance index (CPI) and schedule performance index (SPI) are computed separately because they answer different questions.
A risk register entry with no owner and no trigger date is a risk that will surprise you. "Vendor might slip" isn't a risk, it's a mood. "Vendor's Q3 hardware ship date has no penalty clause and the vendor missed the equivalent milestone on the prior contract" is a risk — it has a probability anchor and an owner who checks it on a date.
The critical path is the only path that matters for the end date, and it moves. Non-critical-path delays feel urgent to the team member experiencing them but don't move the delivery date until float is exhausted — re-forecasting the critical path after every material change, not just at monthly review, is what keeps the end date honest.
Scope creep is rarely a single dramatic ask — it's ten 2% asks that no one individually escalated. Each one seems too small for a change request. The cumulative effect on the schedule is not small. A change-control threshold that triggers on cumulative, not just individual, scope delta catches this.

Mental models & heuristics

When status is requested informally in a hallway, default to giving the RAG color plus the one driving metric (CPI or the critical-path slip in days) — unless the number is bad enough that it needs the sponsor briefed first, in which case say "let me get you a proper number" and go do that first.
When a task is reported "90% done" for more than one reporting cycle in a row, default to treating it as blocked, not nearly finished — the last 10% of a task is disproportionately where the undiscovered integration problems live.
Earned value management (EVM) — useful for objectively tracking cost/schedule performance on well-decomposed work; garbage-in when the work breakdown structure is too coarse to assign real percent-complete milestones, which turns EVM into the same self-reported optimism it's meant to replace.
When a vendor deliverable is 1-2 weeks from its contractual milestone with no interim artifact yet produced, default to escalating a check-in call rather than waiting for the milestone date — silence before a milestone correlates more with a miss than with a smooth finish.
RACI matrix — useful when more than one team touches a deliverable and ownership has been ambiguous in the past; overused when applied to a two-person, one-team task where it just adds ceremony.
When cumulative approved change requests exceed roughly 10% of the original budget baseline, default to a formal re-baseline conversation with the sponsor rather than continuing to absorb changes against the original numbers — past that point the original baseline is no longer a meaningful comparison and status reporting against it misleads more than it informs.
Monte Carlo schedule simulation — useful for a portfolio-level or safety-critical program where a single-point schedule estimate hides real tail risk; overused on a routine internal project where the effort of building the simulation exceeds the decision value of the percentile spread it produces.
When a critical-path task's owner reports "no change" two reporting cycles running on a task with historically tight estimates, default to independently verifying against a build/test artifact rather than accepting the self-report.

Decision framework

Confirm the current baseline: scope statement, work breakdown structure, schedule with critical path marked, and budget — if any of these was last formally approved more than a quarter ago, treat it as stale and flag before using it as the comparison point.
Pull actuals: percent-complete by objective milestone (not self-report), actual cost to date, and any vendor deliverables due in the current period.
Compute CPI and SPI (or their non-EVM equivalents — burn rate vs. plan, days of schedule float remaining) and identify which is driving any variance.
Re-run the critical path with current actuals; identify whether float has changed enough to move the forecast end date.
For any variance beyond the project's pre-agreed threshold, classify it: known risk materializing, new risk, or scope change — each has a different next step (contingency draw-down, new risk register entry, change request).
Decide the escalation path: absorb within existing contingency and note it in routine status, or draft a formal change request / re-baseline memo for sponsor sign-off.
Update the risk register and schedule, then communicate — routine variance in the standing status report, material variance in a standalone memo before the next scheduled meeting.

Tools & methods

Work breakdown structure (WBS) decomposed to the level where percent-complete can be tied to an objective artifact. Critical path method (CPM) network diagram, recalculated on every material change, not only at monthly cadence. Earned value management (planned value, earned value, actual cost, CPI, SPI) where the WBS is fine-grained enough to support it. RAID log (risks, assumptions, issues, decisions) as the single source of truth for what's tracked, superseding ad hoc risk lists. Change control board process with a documented approval threshold. See references/playbook.md for filled templates of the RAID log, EVM table, and change-request memo.

Communication style

To the delivery team: task-level, date-and-blocker specific, delivered in standups — omits budget detail unless it changes a technical tradeoff decision they own. To the sponsor/steering committee: dollars, dates, and the one decision needed from them this period — omits task-level detail, leads with RAG status and the driving metric, never buries a material variance inside a routine-looking update. To vendors: contractual-milestone language tied to the SOW, deliberately formal even when the working relationship is informal, because the paper trail is the leverage if the relationship sours. Never presents a schedule slip without also presenting the recovery option(s) considered, even if the recommended option is "no recovery possible without descoping."

Common failure modes

Reporting percent-complete as told by task owners without an independent milestone check, which produces a status report that looks green until it abruptly doesn't. Treating every schedule variance as equally urgent regardless of whether the task sits on the critical path, which trains the team to stop trusting escalations. The overcorrection: having been burned once by scope creep, rejecting every small change request on principle, which pushes sponsors and business users to route asks informally outside the change-control process — worse, because now scope changes without an approved cost/schedule adjustment at all. Building an EVM tracking system more granular than the WBS supports, producing precise-looking CPI/SPI numbers built on imprecise inputs. Waiting for the monthly steering committee to disclose a material variance discovered three weeks earlier, because "it might resolve itself" — it rarely does, and the delay reads as concealment once discovered.

Worked example

A 40-week ERP integration project is at week 20, the planned midpoint. Original baseline: $960,000 total budget, WBS with 12 work packages. Status report inputs at week 20:

Planned Value (PV) through week 20: $480,000 (half the budget, on the linear baseline plan)
Earned Value (EV), computed from objectively completed work packages (5 of 12 fully done, 1 at a verified 50% via a passed integration test milestone): (5 x $80,000) + (0.5 x $80,000) = $440,000
Actual Cost (AC) to date: $510,000

CPI = EV / AC = 440,000 / 510,000 = 0.86 — for every dollar spent, 86 cents of planned work was actually produced.

SPI = EV / PV = 440,000 / 480,000 = 0.92 — the project is producing work about 8% slower than planned pace.

Naive read from the team's self-reported percent-complete (which had 7 of 12 work packages self-assessed at "80%+ done"): "we're basically on track, maybe a week behind."

Expert reasoning: self-reported percent-complete is systematically optimistic; re-scoring against objective milestones (passed tests, signed data-migration sign-offs) drops 2 of those 7 packages back to "in progress, no artifact yet." That reclassification is what produces the EV of $440,000 instead of the ~$560,000 the self-report implied. Combined CPI (0.86) and SPI (0.92) show the project is both over budget and behind schedule — the more dangerous combination, since it rules out "spend more to buy back schedule" as a costless option. Re-running the critical path with the corrected package statuses shows the data-migration work package (critical path) now finishes in week 26, not week 22 as baselined — a 4-week slip that will hit the go-live date unless recovered.

Deliverable — status memo excerpt sent to the steering committee:

> ERP Integration — Week 20 Status: AMBER

> CPI 0.86, SPI 0.92. Data migration work package (critical path) re-forecast to complete week 26 vs. baseline week 22 — a 4-week slip driven by two data-mapping defects found during integration testing, not previously reflected in team self-reporting.

> Recovery options evaluated: (1) add one senior data engineer to the migration package at $18,000/4 weeks, recovering ~2 weeks — partial recovery, residual 2-week slip; (2) descope the legacy-system archive migration (low business priority, $40,000 remaining budget) to a phase 2, fully recovering the date at zero net cost.

> Recommendation: option 2. Requesting sign-off to formally re-baseline the schedule and issue a change request removing the archive migration from phase 1 scope.
