Key findings
78%
of critical context is lost permanently during employee turnover
1.8 hrs
per developer, per day, spent searching Slack and Jira for context
64%
of engineering teams repeatedly solve bugs that were already resolved
1. Executive summary & methodology
In mid-2026, Memora Research conducted a survey of 350 VPs of Engineering, Chief Technology Officers, Product Directors and DevOps Leads across North America and Europe. The goal of the study was to quantify the financial and operational impact of context decay and knowledge leakage in high-velocity tech companies.
| Respondents | 350 |
|---|---|
| Roles | VPs of Engineering, CTOs, Product Directors, DevOps Leads |
| Regions | North America and Europe |
| Fieldwork | Mid-2026 |
2. Where enterprise knowledge lives
When asked where critical operational decisions and architectural trade-offs are stored, respondents described a highly fragmented picture. Nearly half pointed to chat.
| Location | What is stored there | Share |
|---|---|---|
| Slack / Microsoft Teams | Conversations, thread reviews and bug triage | 48% |
| GitHub / GitLab pull request comments | Code diff trade-offs and code reviews | 22% |
| Jira / Linear issue comments | Customer bug notes and scope changes | 16% |
| Confluence / Notion wikis | Formal, static documentation | 14% |
3. The financial cost of turnover
$148,000average uncaptured context loss per departure of a senior developer or principal architect
The study found that when a senior developer or principal architect leaves, organisations lose an average of $148,000 in uncaptured context per departure, through onboarding drag, duplicated engineering workarounds and delayed release cycles.
