Course path

1 · See the system

Define the goal, boundary, flow unit, and necessary conditions.

2 · Identify

Distinguish accumulation, starvation, cause, and response.

3 · Exploit and subordinate

Protect scarce capacity and align the rest of the system.

4 · Elevate and repeat

Add capability only when justified, then detect movement.

5 · Connect flow to money

Use throughput economics for constrained decisions.

6 · Run the experiment

Design and interpret a four-week constraint test.

Running case

IT-Premium has two customer-triggered value streams—recurring managed services and RFC/project work—that share specialist capacity and cash collection but require separate queues, metrics, and control rules. The production accounting feed identifies recurring income through the Абонплата account at roughly UAH 1.3m per month across the observed quarter. The new time-log evidence shows that incidents and service requests consume most specialist capacity, while clarification is the immediate project-flow constraint. The course teaches how to improve that decision flow without harming service SLA.
