Case study – RE Process Coupling (1) T

Goals T

T

New RE Tool, to create and access specifcations in a distributed development setting

T

Standard tool

T

10% cost reduction

+ Top-down-Initiative + Standardisation – Goal is to generic

Approach T

Setup of project team with internal users under supervision of IT

T

Tool-suppliers present solutions

T

Tool selection and acquisition

T

T

Initial business case, but no specific measurement of effort and errors Configuration of workflows based on available tool functionality

+ Employee involvement – Tool-oriented without process focus – Missing metrics – Artificial processes, based on tool capabilities

Case study – RE process coupling (2) T

Implementation T

T

Estimation of benefits: Effort for specification creation with and without tool support

T

Data migration

T

Training for users

T

Use of support tool is mandatory

Result T T

T

Savings are not achieved Developers work in two parallel worlds: the familiar file system and the new tool Overhead instead of improvement

+ Estimation of potentials - Training is not sufficient for change + Mandatory guidelines

– Cost saving goals were not achieved

– Discontent

Summary ‰

‰

Cost pressure and increasing integration of business processes require coupling of requirements engineering to other processes ‰

Integrated linking of artefacts (e.g. Requirements and Architecture)

‰

Efficient collaboration (e.g. OEM and Supplier)

‰

Consistent data management (e.g. requirements, documentation, design, test)

Process coupling with heterogeneous process and tool landscape is an enormous challange ‰

Process definition and improvement before tool selection

‰

A pre-integrated tool suite such as eASEE supports goals of process coupling: efficiency, consistency, quality, cost reduction

‰

Direct benefits from reduced rework
