Phased Product Delivery

In a situation where the project cannot deliver the complete product by the deadline, there is still the possibility that it might deliver some useful part of it. Information systems projects composed of several subsystems, for example, often implement one subsystem at a time. Tenants can move into some floors in a new office building while there is active construction on other floors, and sections of a new freeway are opened as they are completed rather than waiting for the entire freeway to be complete. Phased delivery has several benefits:

• Something useful is delivered as soon as possible.

• Often, as in the case of information systems, phased delivery is actually preferred because the changes introduced by the new system happen a little at a time. This longer time frame can reduce the negative impacts to ongoing business operations.

• Feedback on the delivered product is used to improve the products still in development.

• By delivering over a longer period, the size of the project team can be reduced; a smaller team can lead to lower communication and coordination costs. In addition, because the people are working for a longer time on the project, project-specific expertise grows. These factors should lead to increased productivity in subsequent project phases and to an overall lower cost for the project.

• Phased delivery allows for phased payment. By spreading the cost of the project over a longer time, a larger budget might be more feasible.

Modularized products, whose components can operate independently, can be delivered in phases. To determine how to phase a product delivery, you need to look for the core functionality—the part of the product that the other pieces rely on—and implement that first. The same criteria may be used in identifying the second and third most important components. When multiple components are equally good candidates, they can be prioritized according to business requirements.

Although some consumer products such as automobiles do not appear to be good candidates for phased delivery ("You'll be getting the windshield in January and the bumpers should arrive in early March . . ."), a limited amount of phased delivery is possible for others. For example, software products can be upgraded cheaply and effectively over time by using the Internet, and current customers can download product updates directly onto their computers from company sites on the World Wide Web.

Trade-off: Phased implementation increases functionality at the expense of schedule. If the approach requires old methods to run concurrently with new methods, it could also temporarily lead to higher operating costs. Impact on risk: When components of a solution are delivered over time, the connections, or interfaces, become high risk. For information systems, that could mean corrupted data. For highway projects, that could mean more accidents.
