Interface Specification Template
When defining interfaces between newly created modules, when interface friction indicates need for clearer specifications, or when onboarding new teams to existing interfaces.
A structured template for documenting how modules interact, including inputs/outputs, timing, quality standards, decision authority, exception handling, change control, escalation processes, and monitoring metrics.
When to Use Interface Specification Template
When defining interfaces between newly created modules, when interface friction indicates need for clearer specifications, or when onboarding new teams to existing interfaces.
How to Apply
Define Inputs/Outputs
Specify what is exchanged between modules
Outputs
- List of inputs provided by each module
- List of outputs received by each module
Establish Timing/Cadence
Define when interactions occur
Outputs
- Deadlines for submissions
- Response time expectations
- Meeting cadences
Set Quality/Performance Standards
Define acceptable ranges, tolerances, accuracy requirements
Outputs
- Measurable quality criteria
- Acceptable tolerance ranges
Assign Decision Authority
Clarify who owns each side of the interface
Outputs
- Named owners for each interface side
- Scope of authority
Define Exception Handling
Specify what happens when standards aren't met
Outputs
- Exception identification criteria
- Response procedures
- Communication requirements
Establish Change Control
Define how to modify interface specifications
Outputs
- Approval requirements for changes
- Review cadence
- Documentation requirements
Create Escalation Process
Define how to resolve disputes
Outputs
- Escalation path
- Timeframes for resolution
- Final decision authority
Set Monitoring Metrics
Define how to track interface health
Outputs
- Key metrics to track
- Reporting frequency
- Threshold triggers
