The Goal is a must read novel for every business owner & employee about turning around a production plant on the verge of being shut down.
Key concepts:
- The Goal: Making money
- Productivity: What you do that results in making money
- Bottleneck: The factor that places a limit on reaching the goal
- Non-bottlenecks: Factors that have spare capacity
Objectives - based on system wide measurements:
- Increase throughput - money coming in
- Reduce investment - inventory and inaccessible money
- Reduce operating expense - money spent to make throughput happen
Management - ask these questions for each objective:
- What to change?
- What to change to?
- How to cause the change?
Five step process of ongoing improvement:
- Step one - identify bottleneck
- Step two - exploit bottleneck
- Step three - subordinate entire system to step two decisions
- Step four - evaluate the systems bottlenecks
- Step five - if the bottleneck has been broken, go to step one
Operational Accounting:
- T = Throughput = money coming in
- I = Inventory = money currently in the system
- OE = Operational Expense = money spent to make throughput happen
- NP = Net profit = throughput - operating expense = T-OE
- ROI = Return on investment = net profit / investment = NP/I
- TAP = TA Productivity = throughput / operating expense = T/OE
- IT = Investment turns (IT) = throughput / investment = T/I
Net profit needs to increase along with simultaneously increasing return on investment and cash flow. Operational accounting should be included in accounting and management courses and software solutions.
