We deliver clarity, structure and impact, with solutions that hold up in everyday use.
Why integration-created work orders silently never schedule, what a due date and a duration have to become before anything can be placed, seeding tasks that arrive with no dates, and who owns the dates afterwards.
Why a synchronous plugin cascade deadlocks and times out on a real program, the two changes that remove it, and the orchestrator, pending-change table, Azure Function and Gantt API pattern we ended up with.
Forward and backward passes over the task graph in working time, what the due date anchors and why exactly one task must be the end, float that is allowed to go negative, and the honest options when a constraint contradicts a dependency.
Where working time actually lives in Project Operations, how to expand a calendar into something you can compute against, the three functions every other part of the engine calls, and the horizon and fallback mistakes that only show up at scale.
