The core team that starts is the core team that finishes.
Continuity is the product. Here is how we measure it, and exactly how sure we are of each number.
Tech Teamz reports ~7.0% voluntary attrition a year (internally audited) and ~74% multi-year retention (all causes). An independent validation of these figures has been commissioned; until it publishes, every figure is labelled internally audited.
- ~7.0% voluntary attrition per year (internally audited)
- ~74% multi-year retention (all causes)
- External validation commissioned (in review)
- Methodology disclosed in full at publication
Measured, and honestly labelled.
| Metric | Value | What it counts | Evidence status |
|---|---|---|---|
| Voluntary attrition (annual) | ~7.0% | Voluntary departures only | Internally audited |
| Multi-year retention | ~74% | All causes, incl. performance-managed exits | Methodology pending |
| External validation | — | Independent audit of the above | In progress · in review |
Separated at source, before either figure is marketed.
The commissioned report discloses the methodology in full, separating voluntary departures from involuntary and performance-managed exits, so both the voluntary-attrition and all-cause retention figures are unimpeachable at source. Attrition is measured across the live engineering roster over a rolling year.
Until the report is published, we present attrition as internally audited and say exactly that. When something is not yet verified, the brand says so.
Continuity is what compounds.
On a multi-year programme, the value is the context an engineer carries, not only the engineer. Low voluntary attrition means the same people keep that context across phases instead of rotating out, so knowledge accumulates rather than resets. That is why retention, honestly measured, is the number to hold us to.

Common questions
Is the ~7% attrition figure externally validated?
Not yet. It is internally audited today; an independent validation of the retention figures has been commissioned and is in review. Every figure is labelled with its evidence status.
What does “voluntary attrition” count?
Voluntary departures only, measured over a year across the live engineering roster, separated from involuntary and performance-managed exits.
What is the multi-year retention figure?
Approximately 74%, all causes (including performance-managed exits). The full methodology is disclosed on publication of the validated report.
Why does retention matter for my programme?
On multi-year work, continuity compounds: the same engineers keep context across phases instead of rotating out. The core team that starts is the core team that finishes.
