Value Stream Mapping: Find the Waste in Your Process
Value Stream Mapping visualizes your entire process, from request to delivery, to separate value-adding work from wasteful delays. It's used to find bottlenecks in manufacturing or software, like code waiting for review.
Empirical Process Control: Steer by Observing, Not by Plan
Empirical process control means steering by observation, not by a rigid upfront plan. Scrum uses this to tackle complex problems, inspecting real work in Sprints to adapt. The footgun is fake transparency—if artifacts hide problems, you're steering blind.
Cycle Time vs. Lead Time: Team Speed vs. Customer Wait
Lead Time is the total time a customer waits for a feature, from request to delivery. Cycle Time is the portion of that time your team is actively working. The footgun is optimizing only for Cycle Time, which can hide major customer-facing delays in the.
The Seven Wastes of Software Development (Muda)
Think of "Muda" as anything consuming resources without adding customer value. This Lean concept helps agile teams spot inefficiencies like partially done work and context switching.
Lean Software Development: Focus on Value, Not Waste
Lean Software Development applies manufacturing principles to code, focusing on maximizing value by systematically eliminating waste. It's the philosophy behind Kanban-style pull systems and delaying decisions.
Waterfall Model: Build Software Like a Building
The Waterfall model treats software development like building a house: each phase is fully completed before the next begins. It suits projects with fixed requirements, but its major footgun is that late-stage changes can force a costly restart from the…
The Agile Manifesto: A Shift in Software Values
The Agile Manifesto is a value system, not a rigid process. It prioritizes people, working software, customer collaboration, and adapting to change over rigid plans and documentation. This philosophy underpins frameworks like Scrum.
