Study Notes

Objectives

To understand the information systems development process for enterprise systems
To learn about traditional approach to information systems design and how it compares with ERP systems design

Traditional Systems Development

Problem definition, systems analysis, feasibility study, detailed design, maintenance, systems design, and implementation are the stages of traditional systems development
Systems designer analyzes bottlenecks, duplication of effort, inconsistencies, and other problems with the current system
Automating the current system is counterproductive due to redundant processes, insufficient data, and inefficient workflow
The traditional life cycle follows a "waterfall" approach: planning and analysis, design, detailed design, implementation

New Approaches to System Design

Three approaches to speed up the building of information systems: prototyping, end-user development, and software packages
Prototyping: models, but does not necessarily speed up the systems implementation process
End-user development: effective for local departmental applications, but not suitable for large-scale production systems
Software packages: offer scale in development, enhancement, and maintenance, and ERP systems are large-scale integrated commercial off-the-shelf software packages

ERP Systems Development Process

Planning, requirements analysis, design, detailed design, implementation, and maintenance are the stages of ERP systems development process
Planning starts with a needs assessment, which provides a business justification for the purchase of the software
Tangible and intangible benefits of ERP systems include inventory reduction, operating cost reductions, overdue accounts collection, process improvement, and reduction in cycle times

ERP Systems Development Process (Requirements Analysis)

Analyzing business processes and specifying the processes to be supported by the ERP package
Importance of selecting a system that fits with the organization's goals and competitive strategy
Most vendors offer best practices for specific industries

ERP Systems Development Process (Design)

Re-engineering the business to fit the software versus customizing the software
Trade-offs between re-engineering and customizing an ERP system include disruption to business operations, cost, and time
