What a 90-day remediation sequence actually looks like
Clients sometimes expect a ranked severity list and stop there. A useful handover goes further: it sequences work so early wins unlock later ones.
Days 1–30 usually address observability gaps on the shared services that appear in multiple incident clusters. Without those signals, later reliability work is guesswork. Days 31–60 tackle the highest blast-radius dependency — often a brittle batch job or an overloaded connection pool. Days 61–90 clear release friction that kept teams shipping around the problem instead of through it.
We keep each item sized so an existing application team can own it without a standing army of external consultants. If an item needs a multi-month rewrite, it is labeled as a strategic track, not jammed into the ninety-day sequence.
Quarterly checkups then re-score the same dimensions. The point is not a vanity percentage; it is confirming that the sequence landed and deciding what belongs in the next ninety days.
