(1) PRIORITY. Eisenhower matrix (urgent vs important), forced ranking (only 1 is #1), ICE scoring (Impact × Confidence × Ease), cost of delay ($/day of not doing this), (2) DEPENDENCIES. blocking chains (A must finish before B starts), critical path (longest sequential chain determines project duration), parallelism (which tasks can overlap), resource conflicts (same person needed for two parallel tasks), external blockers (permits, vendors), (3) ESTIMATION. three-point (Optimistic/Most Likely/Pessimistic), PERT formula: (O + 4M + P) / 6, standard deviation: (P - O) / 6, complexity factors (new technology +50%, team inexperience +30%, external dependencies +40%), historical calibration (what similar task actually took last time), buffer (add 20-30% to PERT), (4) CAPACITY. productive hours per day: 4-5 (not 8). Context switch cost: 23 minutes per interruption (Gloria Mark, UC Irvine). WIP limits: 2-3 concurrent tasks maximum per person. Target utilization: 70-80% (not 100%). 20-30% absorbs variability and unexpected work, (5) OUTCOMES. deliverable-based (not activity-based). SMART criteria: Specific, Measurable, Achievable, Relevant, Time-bound. Acceptance criteria: what does "done" look like? Who signs off? Stakeholder value: why does this deliverable matter? Weekly review cadence. Structured reflection capability for disciplined task organization. forces systematic priority classification, dependency mapping, estimation rigor, capacity awareness, and outcome alignment. Based on critical path method (DuPont, 1957), PERT estimation (US Navy Polaris project, 1958), Eisenhower matrix, and Goldratt's Theory of Constraints. Catches Priority Blindness (everything is marked "high priority". nothing is actually prioritized. a hospital has 12 improvement projects, all labeled "Priority 1. Critical." If everything is critical: nothing is critical. Staff cannot work on 12 projects simultaneously. Result: all 12 projects are 15-25% complete after 6 months. None delivered value. Fix: forced ranking. Only 1 project is #1. Apply ICE scoring: Impact (patient safety improvement) × Confidence (evidence strength) × Ease (resource availability). Rank all 12. Execute top 3 sequentially. Defer the rest. After 6 months: 3 projects 100% complete, delivering value. 9 projects queued with clear start dates), Dependency Ignorance (treating tasks as a flat list instead of a dependency graph. a construction project plan: "1. Frame walls. 2. Pour foundation. 3. Install plumbing. 4. Paint." Problem: you cannot frame walls before the foundation exists. You cannot paint before walls are framed. Plumbing must be roughed-in BEFORE drywall goes up. A flat list ignores these dependencies. Real dependencies: Foundation → Framing → Rough plumbing → Drywall → Paint. Foundation curing: 28 days (ACI 318 standard). This is the critical path. If foundation pours late: EVERYTHING downstream shifts by 28+ days. Parallel work: electrical rough-in can happen DURING plumbing rough-in (different crews, same phase). A flat list misses both: sequential dependencies AND parallel opportunities), Estimation Fantasy (guessing durations without data or methodology. "How long will it take?" "About 2 weeks." Based on what? "Experience." Whose experience? Which project? What complexity? PERT formula: Expected = (Optimistic + 4×Most Likely + Pessimistic) / 6. Example: redesign the hospital lobby. Optimistic: 3 weeks (everything goes perfectly, no change orders). Most Likely: 5 weeks (normal pace, 1-2 minor revisions). Pessimistic: 12 weeks (supply chain delay on custom fixtures, 3 design revisions, permit issues). PERT: (3 + 4×5 + 12) / 6 = 5.83 weeks. Standard deviation: (12-3)/6 = 1.5 weeks. 95% confidence: 5.83 + 2×1.5 = 8.83 weeks. "About 2 weeks" vs PERT's 8.83 weeks. the gut-feel estimate was off by 4.4x), Capacity Amnesia (assuming 8 hours = 8 productive hours. a factory shift is 8 hours. Manager schedules 8 hours of production tasks per worker. Reality: shift handover (15 min), morning briefing (10 min), breaks (2 × 15 min), lunch (30 min), equipment startup/shutdown (20 min), unplanned interruptions (avg 45 min/day). Productive time: 4.5 hours of an 8-hour shift. 56% utilization. Manager scheduled 8 hours of work into 4.5 hours of capacity. Tasks incomplete daily. Context switching (Gloria Mark, UC Irvine, 2004): 23 minutes to regain deep focus after interruption. If a worker is interrupted 6 times/day: 6 × 23 = 138 minutes lost to refocusing. WIP limit: no person should work on more than 2-3 concurrent tasks. Target utilization: 70-80%, not 100%. the remaining 20-30% absorbs variability), and Outcome Disconnect (planning activities instead of deliverables. "Task: research competitor pricing." This is an ACTIVITY, not an outcome. When is it done? After 1 hour of research? 1 day? 1 week? Deliverable version: "Deliver a 1-page competitive pricing matrix: 5 competitors × 3 pricing tiers, with source URLs and date captured. Due: Friday 5pm." The deliverable has: a concrete output (1-page matrix), scope (5 competitors × 3 tiers), acceptance criteria (source URLs, date), and a deadline. Activities are open-ended. Deliverables are completable and verifiable). Call once per task plan, project schedule, or sprint planning session
