01 / FLOW
How does work move?
Lead time, cycle time, time in status, touch time, throughput, and constraints.
The framework
Evidence in. Understanding out.
TDF diagnoses delivery systems by analysing flow, value, predictability, and quality—without reducing complex work to a scoreboard.
Four connected lenses
No single metric tells the truth about delivery. TDF reads related signals together and preserves their context.
02 / PREDICTABILITY
How consistent is delivery?
Variation, historical trends, delivery pressure, and confidence in likely outcomes.
03 / QUALITY
What pressure is quality under?
Defect patterns, resolution ratios, release quality, and value delivery signals.
The diagnostic loop
01
Observe
Build a consistent view of workflow history and configuration from Jira.
02
Measure
Calculate stable, defined metrics from a canonical measurement context.
03
Diagnose
Connect signals, trends, constraints, and the confidence of the evidence.
04
Improve
Use the evidence to focus a team conversation, then observe what changes.
TDF is diagnostic, not prescriptive. It helps teams ask better questions; it does not pretend there is one universal answer.
