Design takeaway

Adopt SysML as a central repository for system architecture and associated effort data to streamline impact analysis for engineering changes.

How to apply

When planning significant design changes, create or update a SysML model that details component relationships and associated development effort. Use this model to trace the potential impact and estimate the required resources.

Project actions

  • 01Use SysML to visually represent your design's components and their relationships.
  • 02Assign estimated effort (e.g., hours, complexity score) to each component or connection in your SysML model.

Method & Evidence

AimHow can SysML be leveraged to efficiently assess the impact and effort of engineering changes in complex systems with numerous interdependencies?
MethodCase study with a proposed methodology
ProcedureA SysML system model was developed in parallel with a structural dynamics simulation model. This model documented the product structure (assemblies and components) and construction structure (force flow). Specific data, such as modeling and calculation times, were stored as attributes of components and assemblies within the SysML model. The method was demonstrated on a powertrain analysis, showing how to quickly estimate the effort for a component change.

Strengths & Limitations

Strengths

  • +Provides a structured approach for managing complex system interdependencies.
  • +Offers a practical method for quantifying engineering change effort.

Limitations

Building a comprehensive SysML model can be time-consuming. The accuracy of the impact analysis relies heavily on the quality of the initial data entered into the model.

Reliability & validity

Reliability would be high if the SysML model and data entry process are standardized. Validity is supported by the demonstration on a complex powertrain system.

Think critically

How might the complexity of the 'construction structure' (force flow) in SysML influence the accuracy of the impact analysis compared to just product structure?

05

Design Principles

"Document system interdependencies and associated effort metrics within a formal modeling language to enable predictive impact analysis."

In complex product development, accurately predicting the effort required for changes is crucial for managing timelines and budgets. This approach provides a structured method to identify and quantify the ripple effects of modifications, enabling more informed decision-making.

06

What This Means for Your Design

Think of SysML like a detailed map of your product. By marking down how much time and effort each part takes to build and how they all connect, you can quickly see how a change to one part will affect everything else and how much work it will be.
