What you will be able to do
- Find the point that actually limits the result of the company
- Estimate the throughput you lose while the constraint stands still, with the conditions under which that loss is real
- See your three weakest areas, with the first step for each
- Set one priority for next week instead of ten
You are not busy. You are blocked.
You chase every problem at once. Quality. Sales. Costs. People. You put out fires, you work fourteen hours a day, and the money still does not come.
Water flows at the speed of its narrowest pipe. Your company earns exactly as much as can pass through its narrowest point. Everything else is noise.
And the worst part: the constraint is often the owner. If every decision waits for your signature, the company cannot grow past you.
What you get

System Scorecard, 45 questions
You score the reality and the tool does the rest: score per area, maturity level, and your three weakest areas with the first step for each. No macros.

Lost throughput calculator
Enter the unrecoverable downtime hours, the units per hour and the throughput per unit, and see how much throughput you really lost, with the conditions under which the loss is real.

Weekly Control Sheet
One printable page a week: three financial signals, this week’s constraint with its proofs, three priorities and one action.

Daily Bottleneck Check
Total downtime per day with the cause, the action, the owner and the due date, plus five rules to verify every day.
The Bottleneck Map
A printable sheet, a guide and an Excel workbook that calculates capacity, load and waiting time. The tool does not declare a bottleneck until four required proofs and five working days of measurement line up. New in this version.

The manual and the start guide
Sixteen short chapters and the exact order in which the system is started. 25 pages, PDF.
Results from the field
Plastic parts producer. Deliveries late, customers threatening to cancel. One moulding machine was the constraint. The machine was not making parts customers were waiting for, so every stopped hour was lost throughput. A third shift cost 200 per hour and paid back easily. Deliveries back to normal in three weeks.
Accounting firm. The owner signed every report and was the bottleneck. A checklist moved approval to the team. Processing dropped from 5 days to 1, and they took on 20% more clients with the same staff.
Building materials wholesaler. Trucks waited 45 minutes for loading while staff did useful but irrelevant work. One dedicated loader. On time deliveries from the next week.
Who is behind this
Nemanja Krstić. Eighteen years of experience, eight of them as a consultant. Before that, an engineer and a manager inside large production systems. Food and beverage, metal, machining, electrical, chemical, textile, construction and defence, plus service companies. This is not a repackaged textbook. Every example came off a real floor.
Guarantee. Read it, use the scorecard, and if it does not show you at least one place where your company is losing money, write to solutions@elcinsight.com and you get your money back. No forms, no questions.
Who it is for
- Owners who fell into daily operations and now do their employees’ jobs
- Directors who are done with excuses and want numbers
- Growing companies where everything still goes through one person
Not for people who already know everything.
Questions
Does this work for a service company?
Yes. In transport the bottleneck is a route or a dispatcher. In software it is the developer everyone waits on. In administration it is an approval procedure with five signatures, four of which nobody reads. The law is the same.
How long does it take?
The manual reads in one afternoon. The scorecard takes about 30 minutes. The weekly sheet takes 10 minutes every Monday.
We already have ISO and written procedures.
Then the scorecard will show you exactly how much of that is used daily and how much gets filled in the week before an audit.
We are small. Is this only for factories?
No. Five people or five hundred, there is still one point where your work moves slowest.
Do I need special software?
No. A PDF reader and Excel. The forms can be printed and filled by hand.
