Setting Task Dependency through Design Structure Matrix

Design Structure Matrix is an analysis tool to identify and assign task dependency. It is designed in the form of a flat (two-dimensional) table in which tasks appear at rows and columns governed by certain rules of dependency. Design structure matrices are developed with use of dependency structure method that lets divide a broader task or project into smaller work items and then establish interrelationships or dependencies between work items.

The key advantages of using design structure matrix and dependency structure method are described below:

• Representing a great number of tasks and their relationships in a compact way
• Using matrix-based analysis to deepen into task dependencies
• Increasing task performance through improving task dependencies

The following steps are carried out to develop design structure matrix for establishing task dependency:

• Interview engineers and managers involved in your project
• Gather data about possible work elements of the project
• Define tasks that constitute your project
• Set sequence for project tasks through prioritization
• Develop a flowchart for tasks
• Identify types of relationship between tasks. There can be parallel, coupled, and sequential relationships
• Determine inputs, outputs, strengths of interaction, etc. between tasks
• Develop design structure matrix and add marks to it
• Share the matrix with engineers and managers for review and commenting
• Collect comments that explain each task and each dependency
• Check and verify comments on the matrix
• Refine the matrix over time by assimilating organizational learning.

CentriQS Task Dependency Solution CentriQS lets users set "Finish-to-Start" task dependency when depending task cannot begin until dependent-on task is completed. As soon as predecessor-successor relationship between the tasks is set, successor task gets state 'Blocked' with reason 'By predecessor' and only after predecessor is done, successor gets unblocked. Assigned users can get notifications both when their tasks get blocked and unblocked.
