SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Teams struggle to ship software faster because they optimize the wrong things — adding people, extending hours, or buying tools — while the real bottlenecks are decision latency, oversized scope, large batches, and approval gates. This Skill provides an evidence-based playbook grounded in DORA, Standish CHAOS, QSM, and McKinsey research to systematically remove those constraints. ## Core Features & Use Cases - Fixed-Time/Variable-Scope Planning: Structure engagements around timeboxes with MoSCoW prioritization, capping Must-Haves at 60% of effort so scope absorbs schedule pressure. - WSJF Prioritization: Rank backlogs using Cost of Delay divided by job size, replacing opinion-driven sequencing with an economic framework. - Flow Optimization: Apply Little's Law, WIP limits (~2/3 of team size), 1–3 day batch sizes, and pipelined timeboxes to cut cycle time and multiply throughput. - Organizational Diagnostics: Identify delivery killers such as Change Advisory Boards, teams larger than 7, long-lived branches, and decision latency over 4 hours, with contract and team-structure fixes. - Use Case: A consultancy starting a new client engagement uses the Week 0 checklist to set up 2-week cycles, a CI/CD pipeline, trunk-based development, and a 4-hour client decision SLA before writing code. ## Quick Start Ask the AI to apply the delivery velocity playbook to plan an MVP scope and set up a two-week fixed-time delivery cycle for your project.

Frequently Asked Questions about delivery-velocity

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I improve software delivery speed on my team?

Focus on the highest-leverage factors: fix time and vary scope, cut low-value features, limit work in progress to about two-thirds of team size, and reduce decision latency below 4 hours. Research shows decision speed is the top predictor of project success, not engineering talent.

How does WSJF prioritization work for backlogs?

WSJF divides Cost of Delay (user value plus time criticality plus risk reduction) by job size, so high-value short jobs rank first. Score each component on a Fibonacci scale, sum them, and divide by estimated size to get an explicit economic ranking.

What is the optimal software team size for productivity?

QSM analysis of 491 projects shows teams of 3–7 are optimal, with 2–5 person teams completing comparable work with roughly one-third the effort of 7–14 person teams. Communication paths grow quadratically, so teams above 9 are significantly less productive.

Do Change Advisory Boards improve deployment stability?

No. DORA research found organizations with formal external approval processes are 2.6 times more likely to be low performers, with no compensating stability benefit. Replace CABs with peer code review and automated deployment gates.

Why does high WIP increase cycle time?

Little's Law states cycle time equals work in progress divided by throughput, so halving WIP halves cycle time at constant throughput. Empirical analysis of 8,000+ work items confirmed lower WIP correlates with shorter lead times.

When should I avoid fixed-price contracts for software projects?

Avoid fixed-price contracts when requirements are uncertain, since research links them to higher failure risk due to frozen upfront scope and adversarial change dynamics. Prefer time-and-materials with fixed-time iterations and a monthly budget cap.
