  Output-design Objectives
        •   Serve the intended purpose
        •   Deliver the right quantity of output
        •   Deliver it to the right place
        •   Provide output on time
        •   Choose the right method
BIS310: Week 8


            Types of Outputs
        • Internal outputs stay inside the system to
          support the system's users and managers
        • External outputs leave the system to trigger
          actions on the part of their recipients or
          confirm actions to their recipients
           – Turnaround outputs are those which are
             typically implemented as a report eventually re-
             enters the system as an input

   System User Issues for Output Design
  • Be aware of output bias.
  • Computer outputs should be simple to read
    and interpret.
  • The timing of computer outputs is important.
  • The distribution of computer outputs must be
    sufficient to assist all relevant system users.
  • The computer outputs must be acceptable to
    the system users who will receive them -> Need
    for training.

BIS310: Week 8


     Internal Controls for Inputs
  • To ensure that the data input to the
    computer is accurate and that the system is
    protected against accidental and intentional
    errors and abuse, including fraud
  • Completeness checks
  • Limit and range checks
  • Combination checks
BIS310: Week 8

         How to Prototype & Design
             Computer Inputs
  •   Step 1: Review Input Requirements
  •   Step 2: Select the GUI Controls
  •   Step 3: Prototype the Input Screen
  •   Step 4: If Necessary, Design or Prototype
      the Source Document

BIS310: Week 8


                 User Interface Design

  • User interface design is the specification of
    a conversation between the system user and
    the computer.
BIS310: Week 8


     Interaction Methods and Devices

  • Command Language Interaction
         – Natural Language Interaction
  • Form Interaction (Fill-in-the-blank)
         – Key-word search
  • Menu Interaction
  • Object-Based Interaction (GUI)
BIS310: Week 8


                 Controlling Data Input

  • One objective of interface design is to
    reduce data entry errors
  • Role of systems analyst is to anticipate user
    errors and design features into the system’s
    interfaces to avoid, detect and correct data
    entry mistakes
BIS310: Week 8


                 Providing Feedback
   1. Status Information
       –   Keeps users informed of what is going on in system
       –   Displaying status information is especially important if the
           operation takes longer than a second or two
   2. Prompting Cues
       –   Best to keep as specific as possible
   3. Error and Warning Messages
       –   Messages should be specific and free of error codes and jargon
       –   User should be guided toward a result rather than scolded
       –   Use terms familiar to user
       –   Be consistent in format and placement of messages
BIS310: Week 8


                     Providing Help
  • Place yourself in user’s place when designing help
  • Guidelines
      – Simplicity
         • Help messages should be short and to the point
      – Organization
         • Information in help messages should be easily absorbed by
           users
      – Demonstrate
         • It is useful to explicitly show users how to perform an
           operation
BIS310: Week 8


                 Designing Dialogues
   • Dialogue
       – Sequence in which information is displayed to
         and obtained from a user
   • Primary design guideline is consistency in
     sequence of actions, keystrokes and
     terminology
   • State Transition Diagram
BIS310: Week 8

        Sample State Transition Diagram
BIS310: Week 8

   The Process of Finalizing Design
           Specifications
  • Deliverables and Outcome
      – Set of physical design specifications
         • Contains detailed specifications for each part of the
           system
BIS310: Week 8


   Assignment 5: Input/Output Design

  • Sample reports: outputs created from your
    prototype system OR your design
  • Sample Input forms (Web-based)
  • Sample of help functions
