What is Constraint Analysis?

Constraint analysis focuses on the bottlenecks within an organization. Under this viewpoint, a manager should only focus on maximizing the utilization of a bottleneck, since the bottleneck controls the overall profitability of the business. Focusing on any other aspect of the business has no impact on profits. This is an important concept, since bottlenecks can be found anywhere within (or even outside of) a business. For example, if sales require a high degree of technical knowledge and all salespeople are fully utilized, then a business will not achieve an incremental increase in sales unless it can somehow hire and train additional salespeople. Similarly, a company will not be able to produce any additional units of a widget if a key part is only available from one supplier, and that supplier is operating at its maximum capacity level.

Constraint Analysis Best Practices

The main point of constraint analysis is to maximize bottleneck utilization. More specifically, the analyst should determine the maximum amount of throughput that can be processed through the bottleneck, which in turn maximizes profitability. The analyst should also note any opportunities to outsource work away from the bottleneck, and whether this will result in increased overall profitability for the business. A further analysis best practice is to identify every possible action that increases the throughput of a bottleneck, such as running extra shifts and overstaffing it, and provide an analysis of the financial impact of these actions.
