Some organizations maintain a common set of development tools or environments. The production plan takes these and other considerations into account. The production plan is instantiated each time a product is built. You also need to understand who will be building the products, in effect, the audience for the production plan. Knowing who the audience is will give you a better idea of how to format the production plan.
Production plans can range from a detailed process model to a much more informal guidebook.
The degree of specificity required in the production plan depends upon the background of the intended product builders, the structure of the organization, the culture of the organization, and the concept of operations for the product line. It will be useful to have at least a preliminary definition of the product line organization and its responsibilities and processes before developing the production plan. The production plan should describe how specific tools are to be applied in order to use, tailor, and evolve the core assets. Then, the appropriate measures can be determined, taken, and tracked to see whether the goals are being achieved. Any production constraints must be identified.
