Tools for Value-Driven Design
Tools intended to help with modelling decisions in a value centric design process. The intent is to keep this as generic as possible, as some of this decision modelling is suited to generic decision-making, non-design activities with a little massaging.
Features
- Concept Design Analysis (CODA) method implementation
- Requirements weighting with a Binary Weighting Matrix
- Programmatic or Spreadsheet based model creation (via Excel workbooks or Google Sheets).
Install
pip install vdd
Documentation
Currently just stored in the repo.
Development
poetry must be installed in the local development environment as a pre-requisite. In the repository root:
poetry install
Versioning
Simple versioning approach: set the version in pyproject.toml and let poetry handle it.
Roadmap
- Model sets for comparative work (rather than a single set of characteristic parameter values)
- Improved visualisation
- Export CODA models to Excel template
- House of Quality style requirement/characteristic weighting
- Pandas everywhere (v1.x)
