How to simplifiy legacy systems ?

 

This white-paper is made of five chapters and is inspired by five case studies conducted with CEISAR’s sponsors (Axa, BNP Paribas, Michelin and Total).
Chapter 1 deals with measuring complexity and its impact on the business.
Chapter 2 proposes a method to conduct legacy simplification projects.
Chapter 3 proposes a Process to actually implement legacy simplification, through Transformation or Replacement.
Chapter 4 answers frequently asked questions about legacy simplification.
Chapter 5 is a short abstract of the case studies that have been conducted to write this white-paper.
Chapters 1, 2 & 5 can be read by any IT executive (CIOs, Architects, Business people), while chapters 3 & 4 are targeted towards more technical people (Architects, Project leaders, Engineers) involved into legacy simplification.

Most of the concepts developped on this website are further developped in our white papers. You can download any white paper freely. Please do not re-use without explicit permission.
