A product is a means of delivering value. Through the use of the product the user achieves something that is useful to them.

Information system products collect, process, and disseminate information to provide value.

Product development is the process of envisioning, creating, and delivering a product.

Product development starts with the identification of an opportunity; a problem to be solved or a need to be met.

Options to realise the opportunity are considered and choices made.

A product is created and used to realise the value present in the opportunity.

In creating a new product there may be much that is unknown; an absence of information.

As the product is developed information about how best to develop the product becomes available.

The best information comes from actual use of the product.

Development should proceed in a manner that maximises the availability and use of information to guide further development.

• Development cycles should be short.
• The product should be made available to, and used by, people who will gain real benefit.
• Feedback from the use of the product should swiftly inform decisions about future development.
