TheThomas-Kilmann Conflict Mode Instrument (TKI)is a psychometric tool that measures an individual’s behavior in conflict situations—specifically, how they handle disagreement with colleagues.

It classifies responses into five modes: Competing, Collaborating, Compromising, Avoiding, and Accommodating.

Why not the others?

Kubler Ross Change Curve:Describes emotional responses to change, not conflict styles.

Westrum’s Typology:Categorizes organizational culture (pathological, bureaucratic, generative) but doesn’t measure individual behavior.

Value Stream Mapping:A process improvement tool, not a behavioral assessment.

Reference/Extract:

“The Thomas-Kilmann instrument helps teams understand how individuals approach conflict and collaboration, enabling better resolution strategies—a key aspect of high-performing DevOps teams.”

The two best measures to showshared successacross technology teams arethroughputandstability:

Throughput(deployment frequency, lead time): Measures how fast teams deliver value.

Stability(change failure rate, MTTR): Measures how reliably systems operate.

Why these two?

Focusing onbothensures teams deliver quicklyandsafely. High throughput without stability causes outages; stability without throughput slows business.

Other options:

Deployment frequency + change lead/cycle time: Both are throughput measures, missing stability.

MTTR + change failure rate: Both are stability, missing throughput.

Employee retention and NPS: People measures, not delivery.

Extract-style reference:

“High performers in DevOps exhibit both high throughput (deployments per day) and high stability (low failure rates, fast recovery), proving it’s possible to achieve both.”
