Analysis Steps

Analysis Steps

1. The system look into the details and figure out what can be improve to make the new system better than the old one.

2. Involving

   • 1. Collecting data about the current system
   • 2. Find out the problems
   • 3. Establish the problems
   • 4. Identify inputs, processing and outputs required
   • 5. Identify the requirements to the new system
   • 6. Calculate the cost-benefit analysis (financial)

3. Methods of getting the information

   • Questionaire
     • given to the users and left with them to complete
     • Usually contain simple questions with easy way of answering like ticking boxes
     • Advantages
       • Questions can be answered quickly and easily
       • Users can be anonymous = more honest answers received
       • Fairly cheap method to achieve data
       • Can be analysed automatically by OMR
     • Disadvantages
       • People usually don't complete pr return them
       • Users are left with questions = can't ask questions
       • If people misunderstood = incorrect data
       • Hard to ask specific questions
   • Interviews
     • face-to-face
     • Involve more detailed questions
     • Interviewer talks to people from different levels of business
     • Questions can varies
     • Advantages
       • Questions can be explained
       • More complex questions = more detailed answers
       • Questions can varies to suit users
       • Get all data because it's face-to-face
     • Disadvantages
       • Takes time
       • Interviewer need to be taken away from doing work = less productive = overall cost↑
       • Face -to face = Users can't be anonymousnswers = may not be honest
   • Observations
     • System analyst sit and watch
     • Watch the system being used and make notes.
     • Advantages
       • Analyst can see exactly what the system does (good/bad)
       • Employee not taken away from work = not expensive
     • Disadvantage
       • Person being watched might feel uncomfortable = work in a differrent way
   • Looking at the documentations
     • Looking at the paper work of the system = get informations to implement the new system
     • Paper work like
       • List of stocks items
       • Employees pay scales
       • Technical documentations
     • Advantages
       • There may be previous analysis = save time
       • Can see existing inputs, precessing and outputs
       • Looking at the amount data = predict the size of the system needed
     • Disadvantages
       • Very time consuming
       • Analyst need to look for the documents = need to be paid for = expensive
       • If the documents are not relevant = time wasted
