summary
Conducted over 40 interviews and four survey waves, the team uses MAXQDA to code themes and finds 78% say teams value reliability while about half still can’t identify which gaps to fix; top barriers are competing priorities, dependencies and measurement difficulty. Policy changes make reliability an explicit performance expectation, teams set realistic SLOs/SIS, and a reliability maturity model guides actions. The research program links reliability investments to engagement, revenue and costs and is already nudging faster work with more stable infrastructure.
