SDLC
Systems Development Life Cycle : the overall process for developing information systems from planning and analysis through implementation and maintenance

Example of Project Team organization

Traditional Systems Development Life Cycle
Detailed analysis of system using tools and techniques to determine problem areas
– Process models – Data models
Phases– Problem definition– Feasibility study– Systems analysis– Systems design– Detailed design– Implementation– Maintenance
![Page 10: 1 Enterprise Resource Planning Dr. Djamal Ziani. 2 CHAPTER 4 ERP Planning and Implementation](https://reader036.vdocument.in/reader036/viewer/2022062803/56649ca15503460f9495fc4d/html5/thumbnails/10.jpg)
10
Traditional Systems Development Life Cycle, continued
Automating current system is counter-productive– Inherit old problems and flaws
Provides opportunity to re-engineer current system Create logical database design before details are
refined Takes too much time Uses a great deal of resources Expensive

New Methodologies
Waterfall methodology
Rapid application development methodology (RAD)
Extreme Programming Methodology
ASAP: Accelerated SAP
![Page 12: 1 Enterprise Resource Planning Dr. Djamal Ziani. 2 CHAPTER 4 ERP Planning and Implementation](https://reader036.vdocument.in/reader036/viewer/2022062803/56649ca15503460f9495fc4d/html5/thumbnails/12.jpg)

Waterfall methodology
Waterfall methodology – a sequential, activity-based process in which each phase in the SDLC is performed sequentially from planning through implementation and maintenance
![Page 13: 1 Enterprise Resource Planning Dr. Djamal Ziani. 2 CHAPTER 4 ERP Planning and Implementation](https://reader036.vdocument.in/reader036/viewer/2022062803/56649ca15503460f9495fc4d/html5/thumbnails/13.jpg)
13
Rapid application development methodology (RAD)
Emphasizes extensive user involvement in the rapid and evolutionary construction of working prototypes of a system to accelerate the systems development process
The prototype is an essential part of the analysis phase when using a RAD methodology
– Prototype – a smaller-scale representation or working model of the users’ requirements or a proposed design for an information system
![Page 14: 1 Enterprise Resource Planning Dr. Djamal Ziani. 2 CHAPTER 4 ERP Planning and Implementation](https://reader036.vdocument.in/reader036/viewer/2022062803/56649ca15503460f9495fc4d/html5/thumbnails/14.jpg)

The Prototyping Process
![Page 15: 1 Enterprise Resource Planning Dr. Djamal Ziani. 2 CHAPTER 4 ERP Planning and Implementation](https://reader036.vdocument.in/reader036/viewer/2022062803/56649ca15503460f9495fc4d/html5/thumbnails/15.jpg)

Extreme Programming Methodology
Extreme programming (XP) methodology – breaks a project into tiny phases, and developers cannot continue on to the next phase until the first phase is complete
![Page 16: 1 Enterprise Resource Planning Dr. Djamal Ziani. 2 CHAPTER 4 ERP Planning and Implementation](https://reader036.vdocument.in/reader036/viewer/2022062803/56649ca15503460f9495fc4d/html5/thumbnails/16.jpg)

ASAP
Accelerated SAP (ASAP) is SAP's standard implementation methodology. It contains the Roadmap, a step-by-step guide that incorporates experience from many years of implementing R/3.
Accelerated SAP contains a multitude of tools, accelerators and useful information to assist all team members in implementing R/3. Quality checks are incorporated at the end of each phase to easily monitor deliverables and critical success factors.

Goal Setting Define project goals & objectives
Implementation strategy 1.Clarify the scope of implementation 2.Establish the project organization and relevant committees and assign
resources
Implementation Sequence Define sequence in project has to be
executed
Team Core team+ project team+
consultant team
Sign Off At the end of phase every above steps will be documented & will be signed off
with the client
Phase 1 : Project Preparation
During this phase the team goes through initial planning and preparation for SAP project.

Phase 2 : Business Blueprint
SCOPE DOCUMENTThis document will consists of
questionnaire of entire business
process
AS IS 1.Understanding the business Process
from the core team. 2.Based on the input ASIS document has to be created
according to module wise

process in SAP based on ASIS 2.Module wise TOBE document has to
be created
GAP ANALYSIS 1.The GAP b/w ASIS process & TOBE process
is called GAP analysis ie., The inputs or the business process which can’t mapped into
standard SAP will be analyzed here 2.GAP document has to be created
SIGN OFF Each process above has to be
taken sign off from client
The purpose of this phase is to achieve a common understanding of how the company intends to run SAP to support their business. The result is the Business Blueprint, a detailed documentation of the results gathered during requirements workshops.
