Leaving slack in your plans and your money, because the future will surprise you.

What it means
Room for error means you do not plan for the best case. You plan with slack, so that when something goes wrong, the business bends instead of breaks. Slack can be money, time, stock, people or capacity.
The future will surprise you. A client will pay late. A key person will leave. A supplier will miss a date. You cannot predict which one, but you can be sure that something will come. So you build in a cushion before it is needed, not after.
Why it matters
Many strong businesses fail not because the idea was wrong but because one bad stretch arrived when there was no buffer. Slack feels like waste when things go well. It feels like genius when things go badly. A buffer buys you time, and time lets you think clearly instead of reacting in panic.
When you get this right:
- A late payment becomes an annoyance, not a crisis.
- You can say no to bad deals because you are not desperate.
- You can take reasonable risks, since a miss will not sink you.
How to use it
- Work out your monthly fixed costs: salaries, rent, loan instalments, tax dues. Add them up.
- Decide how many months of those costs you want in reserve. Start with one month and build toward three.
- Look at your plans and add a margin. If you think a project takes six weeks, tell the client eight.
- Find one single point of failure, such as one supplier, one big client or one skilled person. Start a backup this week.
Common mistakes
- Treating spare cash as idle money that must be put to work at once.
- Promising delivery dates based on the best case.
- Building a buffer once and never refilling it.
- Adding slack to money but not to time and people.
