Systems Development Life Cycle Back

IT specialists within an organization build the organization’s system by

• Planning – establishing the plans for creating an information system by
  
  • Defining the system to be developed – based on the systems prioritized according to the organization’s critical success factor (CSF), a system must be identified and chosen
    
  • the project scope – a high level of system requirements must be defined and put into a project scope document
    
  • Developing the project plan – all details from tasks to be completed, who completed them and when they were completed must be formalized
    
  • Managing and monitoring the project plan – this allows the organization to stay on track, creating project milestones and feature creeps which allow you to add to the initial plan
    
• Analysis – the users and IT specials collaborate to collect, comprehend, and logistically formalize business requirements by
  
  • Gathering the business requirements – IT specialists and knowledge workers collaborate in a joint application design (JAD) and discuss which tasks to undertake to make the system most successful
    
  • Analyzing the requirements – business requirements are prioritized and put in a requirements definition document where the knowledge worker will approve and place their signatures
    
• Design – this is where the technical blueprint of the system is created by
  
  • Designing the technical architecture – choosing amongst the architectural designs of telecommunications, hardware and software that will best suit the organization’s system and future needs
    
  • Designing the systems model – graphically creating a model from graphical user interface (GUI), GUI screen design, and databases, to placement of objects on screen
    
• Development – executing the design into a physical system by
  • Building the technical architecture – purchasing the material needed to build the system
    
  • Building the database and programs – the IT specials write programs which will be used on the system
    
• Testing – testing the developed system
  
  • Write the test conditions – test conditions are conducted by comparing expected outcomes to actual outcomes. If these differ, a bug is generated and a backtrack to the development stage must occur.
    
• Implementation – the systems are placed and used in the actual workforce and
  
  • The user guide is created
    
  • Training is provided to the users of the system - usually through workshops or online
    
• Maintenance – keeping the system up to date with the changes in the organization and ensuring it meets the goals of the organization by
  
  • Building a help desk to support the system users – having a team available to aid technical difficulties and answer questions
    
  • Implementing changes to the system when necessary
