The Iron Triangle and Crunch Time
Crunch is not bad luck.
It is where the course led.
Time, budget, scope: pick two. Quality pays for the third.
The Iron Triangle says a project can fix two of time, budget and scope, never all three. When all three are nailed down anyway, something else gives: quality, along with the people who make it. Crunch time is rarely bad luck. It is the sum of many small choices made long before.
All hands on deck was meant for the storm, not for every day.
What the constant alarm costsThe quality
Gives first, quietly, when the date holds.
The upkeep
What was built stops being cared for.
The planning
There is never a quiet hour to sit down.
The crew
Tired, then sick, then gone.
One more push, and then it gets calmer, right?
Nobody gets credit for the storm that never came
Every exception teaches the system what is possible.
Exception by exception, it becomes the rule.
- 1Once, on a weekendIt works. The date holds.
- 2Back a day early from leaveIt works again.
- 3Leave postponedNobody planned it. Everyone expects it.
- 4“That’s just how we work here”Nobody remembers it was ever different.
Five ways into the crunch
Crunch time is a result. Many small steps lead there, long before the storm.
How crunch time shows
Typical indicators. Not a complete list, but the ones that show up most often.
Flip the effort curve
Crunch makes up at the end for what the plan left out.
Spend it at the start instead, while there is still time to change course.
- Chart the real effortPlan the work and its mechanics first, until at least 80% of the real effort is visible.
- Incremental deliveryDeliver in small steps and adjust the course, so the cargo cannot creep.
- Definition of DoneSpell out requirements and gates, then revisit them at a steady rhythm.
Celebrate the calm arrival, not the rescue.
Pressure is human, and sometimes it helps a crew act. It turns into crunch when it becomes the norm, when there is no longer a moment to sit down and plan. The more complex the work, the more that moment matters.
