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
