Two dominant product development models that support system approaches for product planning:

Integrated Product Development (IPD) - Defined by Andreasen and Heijn in 1980. - 4 phases for design requirements stemming from stakeholders

analysis.

System Engineering and Integration -Defined by the International Council on Systems Engineering. - Identification, documentation, definition of the stakeholder

requirements. - Clear structure, but limited success.

Method evaluation through studies drawn from health sector and fast moving consumer sector.
