Distinctions
Is
| Identity | Explanation |
|---|---|
| Expansion beyond agreed boundaries | More work is added after scope has been agreed |
| Unpriced additions | Additional features, requirements, or obligations are accepted without explicit tradeoffs |
| Boundary erosion | The edge of the request becomes porous, allowing new work to enter without re-planning |
| Delivery commitment distortion | Original timeline, cost, or capacity assumptions remain in place after the work grows |
Is Not
| Other | Why It’s Different |
|---|---|
| The Single-Story Illusion | The Single-Story Illusion is about a stable business objective hiding changes to definition of done; scope creep is about expansion beyond agreed boundaries |
| Healthy discovery | Discovery changes understanding before commitment; scope creep adds work after commitment without resetting expectations |
| Legitimate reprioritization | Reprioritization explicitly trades one thing for another; scope creep quietly accumulates |
| Gold plating | Gold plating is extra work added by the delivery team; scope creep often comes from stakeholder or organizational additions |
Boundary
Scope Creep occurs when the agreed boundary of work expands without an explicit change to timeline, priority, cost, or scope tradeoffs.
Systems
Relationships
| Relationship | Concept | Rationale |
|---|---|---|
| Related to | The Single-Story Illusion | Both obscure delivery impact, but scope creep emphasizes expansion while The Single-Story Illusion emphasizes mismatched counting units |
| Reinforces | False Precision | Plans remain precise even after the amount of work has changed |
| Can produce | Blame Culture | Teams are blamed for missing commitments after unpriced work has been added |
Perspectives
| Stance | Who (Point) | What They See (View) | Optimize For | Insight | Blind Spots |
|---|---|---|---|---|---|
| Mr. Just-One-More | Requester or stakeholder | Each addition looks small in isolation | Getting useful changes included while attention is available | Small changes often are legitimate and valuable | Small additions compound into different work when they are not traded off against time, capacity, or other scope |
| The Boundary Keeper | Delivery team or project lead | The original commitment no longer matches the work being asked for | Protecting capacity, timelines, and delivery credibility | Scope changes need visible tradeoffs | Can sound rigid if every change is treated as a threat |
| The Relationship Smoother | Accountable lead, manager, or partner team | Saying yes preserves momentum and goodwill | Keeping collaboration easy and avoiding conflict | Some flexibility protects trust and responsiveness | May absorb unpriced work until the team becomes overloaded or resentful |
| The Tradeoff Maker | Product owner, planner, or prioritization steward | New work is possible only by changing another variable | Preserving honesty about scope, time, cost, and priority | Scope creep is often a tradeoff conversation that never happened | Can over-formalize small changes when the decision cost is higher than the work |
