Dependency Management
The process of identifying, tracking, and managing the relationships between tasks, teams, or systems where one element relies on another for completion or input.
In-Depth Explanation
Dependency management is the practice of identifying and handling the relationships between work items, teams, and systems that create constraints on project delivery. Unmanaged dependencies are one of the most common causes of project delays.
Types of dependencies:
- Finish-to-Start (FS): Task B cannot start until Task A finishes (most common)
- Start-to-Start (SS): Task B cannot start until Task A starts
- Finish-to-Finish (FF): Task B cannot finish until Task A finishes
- Start-to-Finish (SF): Task B cannot finish until Task A starts (rare)
Dependency categories:
- Mandatory (hard): Inherent in the nature of the work (must pour foundation before building walls)
- Discretionary (soft): Based on preference or best practice (could be changed)
- External: Depends on factors outside the project team (vendor delivery, regulatory approval)
- Internal: Between activities within the project team's control
Dependency management process:
- Identify: Map all dependencies during planning and refinement
- Document: Record dependencies in project plans, boards, or tools
- Communicate: Ensure all parties understand their dependencies
- Monitor: Track the status of dependencies actively
- Mitigate: Develop contingency plans for dependency risks
- Resolve: Address blocked dependencies promptly
Strategies for reducing dependencies:
- Design work to minimise cross-team dependencies
- Use APIs and interfaces to decouple system dependencies
- Co-locate or align schedules of dependent teams
- Use architectural patterns that reduce coupling
- Build mock services or stubs to enable parallel work
- Sequence work to manage dependencies within sprints
Business Context
Effective dependency management prevents one team or task from blocking another, reduces project delays, and enables more predictable delivery of complex projects.
How Clever Ops Uses This
Clever Ops actively manages dependencies in all client projects, identifying cross-team and external dependencies early and building mitigation strategies. We help Australian businesses reduce dependency-related delays through better planning, architecture, and communication practices.
Example Use Case
"A project team identifies that their mobile app development depends on an API being completed by another team. They create mock API responses to enable parallel development and schedule a dependency sync meeting with the API team."
