Applying Agile Requirements Engineering Approach for Re-engineering & Changes in existing Brownfield Adaptive Systems

TL;DR

This paper presents an Agile Requirements Engineering approach tailored for re-engineering and managing changes in existing Brownfield adaptive systems, integrating gap analysis and prioritization within SCRUM.

Contribution

It introduces a modified RE approach that incorporates gap analysis and modeling techniques for effective re-engineering in agile environments.

Findings

The approach facilitates structured re-engineering with 80/20 rule application.

It bridges the gap between traditional requirements engineering and agile methods.

Practical implementation of the approach is demonstrated in Brownfield systems.

Abstract

Requirements Engineering (RE) is a key activity in the development of software systems and is concerned with the identification of the goals of stakeholders and their elaboration into precise statements of desired services and behavior. The research describes an Agile Requirements Engineering approach for re-engineering & changes in existing Brownfield adaptive system. The approach has few modifications that can be used as a part of SCRUM development process for re-engineering & changes. The approach illustrates the re-engineering & changes requirements through introduction of GAP analysis & requirements structuring & prioritization by creating AS-IS & TO-BE models with 80 / 20 rule. An attempt to close the gap between requirements engineering & agile methods in form of this approach is provided for practical implementation.
