Design rationale

In "Automatic Generation" [4] method, design rationales are automatically generated from an execution history at low cost.

One advantage of Toulmin model is that it uses words and concepts which can be easily understood by most people. In these systems, the designer creates the design and the DR system generates the rationale for it based on the system's stored knowledge.

This allows for non-intrusive capture.

But it's hard to design such a schema. Another advantage of informal representation is that the rationale stored can be in the original format found in the natural byproducts of the design process.

If you want to read more about defining success and the importance it plays in the design process when working with cross functional partners, I wrote about my experience here.

It also suggests some areas for future work. The "Methodological byproduct" [4] method captures rationales during the process of design following a schema. Negotiations are also needed when conflicts exist between the intents of different designers. Design teaching — The design rationale could be used as a resource to teach people who are unfamiliar with the design and the system. In the formal representation, the rationale must be collected under a strict format so that the rationale can be interpreted and understood by computers. Information can be represented in a range from formal computer readable to informal not computer readable. One is to compare when the rationale is captured. Next Design Rationale Design rationale is about explaining why a product has been designed the way it has.

Design teaching — The design rationale could be used as a resource to teach people who are unfamiliar with the design and the system. It is especially important to let the designer know why the decisions were made.

It is a graphical notation that allows designers to visibly lay out the reasoning behind design decisions.

Without the presence of rationale that indicates this, the design may be changed in a way that could be harmful. The "Methodological byproduct" [4] method captures rationales during the process of design following a schema. Which would you decide to implement and why? For example, design reuse and design maintenance are both concerned with knowing which parts of the design support which requirements and how the design will need to change if a requirement is modified. Design rationale behind the decisions is captured during the process of the WinWin model and will be used by stakeholders and the designers to improve their later decision making. Rationale capture is the process of acquiring rationale information to a rationale management Capture methods A method called "Reconstruction" [4] captures rationales in a raw form such as video, and then reconstruct them into a more structured form. In addition, it requires that data be given to it in a more rigid format. Design reuse — The design rationale is used to determine how the existing design could be reused for a new requirement with or without any changes in it. If however the context does change then new design decisions can be made for this new context, but in the light of the decisions made for the older context.
