The Deliverable Prototype is the first development step in implementing Iterative Development on your project. The Deliverable Prototype is a complete skeletal model of the deliverable application. As such, it contains source files for data entities, domain modules, user screens and supporting code modules called out in the technical design.

The Deliverable Prototype contains all new or novel combinations of technologies contemplated in the project technical design. This includes any new database access technologies, user interface component sets, user interface themes, reporting tools and deployment platforms needed to demonstrate feasibility.

The solution domain naming convention, called out in the project technical design, is codified and vetted in this skeletal application.

The Deliverable Prototype is the primary responsibility of the project technical lead until the first Project Build and Demonstration is completed.


Creating a Deliverable Prototype provides the following advantages:

  • A Deliverable prototype, at the beginning of a project, is an energizing team building experience: new project, new technologies, new possibilities, new technical skills.
  • A Deliverable Prototype forces the project team to think through the complete application including a first version of a user interface.
  • A Deliverable Prototype exposes any complex interactions between project features and provides a context within which to simplify them.
  • A Deliverable Prototype forces the project team to devise and optimize a workable deployment scheme.
  • The user community representative has tangible progress to show and solicit feedback on.

In addition, a Deliverable Prototype that is available for demonstration and feedback will generate specific requests for functionality and user interface features that are overlooked when application design is performed starting with a blank screen. This allocation of resources, beginning with a tangible but empty demonstration, energizes the prospective user community with the prospect that their concerns are being heard and shaping the application they will soon use. This exercise also empowers the user community representative and helps start the process of prioritizing feature requests into individual milestone requirements lists.

Work Product

The Deliverable Prototype and Deployment scheme are critical inputs for the specification of the Project Delivery System. By completing this step, your project and management are assured that you can deliver and deploy your latest version of a working prototype, at the very least to a location on your development network.

The sole difference between any of your prototypes and a deployable product is now a successful acceptance test. Once you complete automating your build and deployment scripts, each successive project build will be more predictable, reliable and testable because the error-prone complexity and custom nature of your unique project build will be encapsulated. When deadlines loom, this effort pays for itself many times over and can be the margin of success by freeing resources for testing and handling exceptional conditions, only found in the production environment.
