Knowledge Work

Literature on knowledge work in organizations provides an understanding of the problem.

Description of the problem:• Characteristics of knowledge

work• Complex vs. Complicated

problems• Roles in knowledge work

Adaptive Case Management

Adaptive case management is a novel approach to support knowledge-intensive processes.

Solution ideas from ACM:• Essential requirements for ACM

support• Emergent design of processes• Evolution of processes with

templates

Social Principles and Patterns

Knowledge work relies on the successful collaboration of different roles.

Facilitating collaboration:• Building successful online

communities• Learning from existing

communities on the web• Principles and patterns

Introduction – Artefact-oriented RE – Research Questions – Development - Roadmap

Goal Orientation Describe which goals should be achieved Goals guide the stream of work Replaces traditional process model

Emergence Empowerment and participation of end users Adaptability of templates at run-time Continuous improvement of templates

Data Centricity Data as driver for knowledge work Goal-oriented transformation of data Integration of processes and data

Collaboration Knowledge creation through interaction Building a successful online community

Case Templates Sharing and preservation of knowledge Access to recurring best practice patterns

General Solution: Empowering Users to Collaboratively Structure Knowledge-Intensive Processes

Activity-Orientation:Concrete process with a set of methods performed in a particular order

Artefact-Orientation:Concentration on artefacts, which are coupled to milestones, roles, etc.

Designtime vs. Runtime

29.07.2014Michael Bigontina 9

Based on: Mendez Fernandez et al - A Case Study on the Application of an Artefact-based Requirements Engineering Approach

Customisation Approach

Stage 1: Initial Project Set-Up

• Create Artefacts• Assign Roles• Define Milestones• Set-Up Infrastructure

Stage 2: Project-specific Execution Strategy

Project Background,

Documents, …

Artefact Type

Dynamic Content Creation:

• Create Content Item• Reflect on Project

Parameters• Analyse Possibilities• Document Rationale• Create Content

Designtime Runtime

Introduction – Artefact-oriented RE – Research Questions – Development - Roadmap

Research questions

How can software support artefact-oriented Requirements

Engineering?

What are characteristics of the process in the generic meta-model

for artefact-orientation?

How can concrete AMDiRE or BISA Requirements Engineering Processes be supported?

Artefact

Content ItemConcept

Type(e.g. as

Text)could be another Artefact

Concept Item Representation: Text, Number, Boolean, Enum, Date, FileConcept Representation: new page (as for Artefacts) containing concepts and concept items
