Short answer: You can loosen a business constraint in 14 days without new spend by using the first three of the Theory of Constraints' five focusing steps: identify the link, exploit it (get more from what you already have), and subordinate everything else to it (pause the work that competes with it). Spend money only at step four, and only if the first three are not enough.

You have found the link that limits your growth, perhaps with the 8-link growth chain check. The temptation now is to buy your way out: an agency, a hire, new software. Hold off for 14 days. A constraint is often being wasted by the work around it, and fixing that costs time, not money. What you learn also tells you whether spending is needed at all. This is the second half of the Simple-Growth approach to SME business growth and finding the real constraint.

What are the five focusing steps?

Eliyahu Goldratt's method has five steps, set out by the Theory of Constraints Institute. Most owners jump to step four.

  • Identify the constraint: the one link that limits the whole business.
  • Exploit it: get the most from it using what you already have.
  • Subordinate everything else: align the rest of the business to the constraint and stop work that competes with it.
  • Elevate it: add capacity or investment, but only once steps two and three are used up.
  • Repeat: once you lift it, the weakest link moves, so go back to step one.

What does the 14-day plan look like?

  • Days 1 and 2, name and measure: write the constraint in one sentence, choose the one number you will watch and record its starting value.
  • Days 3 to 7, exploit: pick two or three moves that get more from the link with no new spend (examples below).
  • Days 8 to 10, subordinate: list everything that competes for the same time, attention or capacity, and pause one or two of those items.
  • Days 11 to 13, run it: let the changes work and resist adding anything new.
  • Day 14, review: compare the number with its starting value and decide whether to keep going, change the moves or move to step four.

What can you exploit at each link, for free?

  • Direction: write a one-page plan and say no, for 14 days, to anything that does not serve it. A rolling plan helps: see why a 90-day roadmap beats a 5-year plan.
  • Attention: pick the one channel that already brings you customers, pause the rest, and ask your five best customers how they found you.
  • Offer: ask three recent lost prospects why they said no, then tighten how you describe what you sell.
  • Conversion: reply to every enquiry the same day and add a three-step follow-up. See the follow-up gap that kills most SME sales.
  • Delivery capacity: write a checklist for the job you repeat most and remove one handover step.
  • Margin and cash: invoice on completion, and work out the real margin on your five biggest jobs.
  • Retention and referral: call your ten best customers and ask each for one introduction. See why existing customers are your best pipeline.
  • Owner and team capacity: list the decisions you make every week and hand one over with a clear definition of done. See why delegation fails without a definition of done.

When is it time to spend money?

After day 14, if your number has moved, find the new weakest link and run the cycle again. If it has not moved and the link still caps your results, you have earned the right to invest. Set a measure and a review date before you spend, so you know when the investment is working. That is the difference between spending to hope and spending to fix.

Individual results vary and depend on the business and the work the owner puts in.

FAQ

Does no new spend mean no cost at all?

It means no new money on tools, hires or advertising. It does cost your time and attention, which is why the plan limits you to two or three moves.

What if the constraint is cash?

Exploit what you already have: invoice sooner, chase overdue accounts and check which jobs actually make money. Avoid new borrowing until you have run the cycle once.

What if nothing moves in 14 days?

Check that you picked the right link and measured the right number. If both are right and the link still caps results, move to step four and invest with a clear measure and review date.

Can I work on two constraints at once?

Fix one at a time. Working on several spreads your attention thin and hides which change made the difference.
