An Integrated Product Team (IPT) is a team composed of representatives from appropriate functional disciplines working together to build successful programs, identify and resolve issues, and make sound and timely recommendations to facilitate decision-making. IPTs are used in complex development programs/projects for review and decision-making. The emphasis of the IPT is on the involvement of all Stakeholders (users, customers, management, developers, contractors) in a collaborative forum. 
Definition: A multi-disciplined team made up of members from specific disciplines working together on a project to identify, address and resolve issues to help achieve project goals and objectives.
Types of Integrated Product Teams (IPT)
There are three (3) types of IPTs that each acquisition program will implement: [2,3]
- Overarching IPTs (OIPTs): Focus on strategic guidance, program assessment, and issue resolution;
- Working-level IPTs (WIPTs): Identify and resolve program issues, determine program status, and seek opportunities for acquisition reform; and
- Program-level IPTs (PIPTs): Focus on program execution and may include representatives from both government and industry after contract award.
Integrated Product Team (IPT) in DoD Acquisitions
Integrated Product and Process Development (IPPD) is the DoD management technique that simultaneously integrates all essential acquisition activities through the use of IPT to optimize design, manufacturing, and supportability processes.
Integrated Product Teams (IPT) in Logistics
The Program Manager (PM) and/or Product Support Manager (PSM) should establish multidisciplinary teams to develop and manage the implementation of the performance-based support strategy. The IPTs should consider all factors and criteria necessary to achieve an optimum support strategy using the best capabilities of the public and private sectors in a cost-effective manner.
DoD Component and Defense Logistics Agency (DLA) logistics activities should participate in support strategy development and IPTs to ensure the support concept is integrated with other logistics support and combat support functions and provide agile and robust combat capability. These participants can help to ensure effective integration of system-oriented approaches with commodity-oriented approaches (common support approaches), optimize support to users, and maximize total logistics system value. 
After 20 years of working as a Program Manager, I have developed a list of best practices when utilizing an IPT. These best practices are:
- Keep the IPT size to the smallest size possible. Too many people lead to delays
- Communicate roles and responsibilities from the start
- Establish clear goals and objectives
- Have a meeting schedule and stick to it
- Make sure everyone knows their role and assignments after each meeting
- In 1995, the Secretary of Defense directed that the Department adopt IPTs as the preferred approach for development, review, and oversight of the acquisition process.
