Axiomatic Product Development Lifecycle (APDL) (also known as Transdisciplinary System Development Lifecycle (TSDL), and Transdisciplinary Product Development Lifecycle (TPDL) ) is a systems engineering product development model proposed by Bulent Gumus that extends the Axiomatic design (AD) method.[1][2] APDL covers the whole product lifecycle including early factors that affect the entire cycle such as development testing, input constraints and system components.
APDL provides an iterative and incremental way for a team of transdisciplinary members to approach holistic product development. A practical outcome includes capturing and managing product design knowledge. The APDL model addresses some weak patterns experienced in previous development models regarding quality of the design, requirements management, change management, project management, and communication between stakeholders. Practicing APDL may reduce development time and project cost.
