Abstract: Based on the Activity Theory， by analyzing the components of an activity and the relationship of the process integration， a framework for an adaptive process integration is presented. According to the situation and characteristic of the product development process， a number of the important issues on process integration， process description， adaptive planning principle， process tracking and process monitoring display are discussed. An adaptive process management feedback mechanism and the system architecture also are given. At last， the design instance of the pill is demonstrated.

Key words: activity theory, activity-cell, process integration, process meta-model
