• Overview

• PRIME Knowledge Management approach

• KARE Requirement Engineering approach

• Outlook

Overview

• The global competition asks for high product quality at low costs and shortened times of development and production

• Optimisation and rationalisation of business processes is from high relevance

• The introduction and integration of advanced IT-technologies to the business environment and processes is of particular importance

• The application of Collaborative Engineering becomes more and more important in distributed business environments

Motivation

Actually KM is

• limited to special applications
• limited within borders of organisational units
• limited to certain PLC phases

Therefore the PRIME methodology enables

• the extension of the scope to every business application
• to open the application of KM over company borders and the integration of Extended Enterprise aspects
• the coverage over the complete PLC

The conceptual hierarchy / approach

PRIME is a top-down approach

Workflows and Roles - Applying KM

Requirements Engineering process

Requirements are mostly specified in natural language text. This is the reason for:

• ambiguities
• inconsistencies
• missing requirements

Solution:

Using a model-based approach for product requirements by using enterprise knowledge in distributed engineering environments

The KARE workbench

is a set of tools to support the requirements engineering, formalisation and management process on acquirer and supplier side:
