M4- effective capacity

Business Process Management (BPM) Overview

• Effective Capacity

  • Definition: Measurement of the maximum achievable output of a process under normal conditions.

  • Flow Rate (R):

    • Definition: The amount of flow units processed in a given time period.

    • Measurement:

      • Observe the process over an extended period.

      • Count the total number of flow units processed during this time.

      • Calculate the average number of flow units per unit of time.

Key Components of Effective Capacity

1. Unit Load of a Resource Unit

• Definition: The average time required by a resource (i) to process one flow unit.

  • Represented as: Ti

2. Effective Capacity of a Resource Unit

• Calculation:

  • Inverse of the unit load: 1 / Ti

• Number of Resource Units:

  • Represented as: Ci

3. Effective Capacity of the Resource Pool

• Calculation Method:

  • Sum of effective capacities for each resource unit in the pool: Ci / Ti

Bottlenecks in BPM

• Definition: The slowest resource pool in the process that limits overall output.

• Impact:

  • The effective capacity of the bottleneck determines the effective capacity of the entire process.

Capacity Utilization

• Formula:

  • Represented as: ui = R / Effective Capacity
