What a Working System Actually Requires
A working operational system does not depend on any specific tool. It requires four things that exist independently of whatever platform you are using.
A clear workflow. Not a task list. A defined sequence that tells people when work starts, what happens at each step, and what a completed output looks like. Without this, work gets done differently every time.
Defined ownership. Every task, process, and decision has one named person responsible for it. Not a team. One person. Shared responsibility is the same as no responsibility.
Standard documentation. Recurring work is written down in a format simple enough to follow without asking someone to explain it. If a new person needed to pick it up tomorrow, they could do so without a briefing.
A consistent rhythm. Weekly planning. Regular check-ins. A review cycle that keeps the system active and updated. Without rhythm, even a well-designed system goes stale and stops being used.
None of these are features in a tool. They are decisions about how the business operates. Make those decisions first. Then choose the tool that fits.
