Project Evaluation

• Effectiveness is a measure of how well a system perform its intended function.

  • Completeness, all functions and data is included
  • Readability, how easily a system is understood
  • Usability, ease with how the end-user can use the system
  • Timeliness, how quickly a system process and deliver outputs
  • Accuracy, correctness of system output
  • Relevance, provides useful information that is relevant
  • Reliability, consistency of program
  • Flexability, how easy it is to adapt the system
  • Security, ability to protect data from unauthorised users
  • Mantainability, easy to update
• Control structures are used to control the flow of execution of a program.

  • Sequence, instructions are executed line by line in the sequence they were written
  • Selection, used for branching when a chocie is made between two or more alternate paths
  • Iteration, repeat section of a code multiple times
• Validation techniques checks that input data are reasonable

  • Existence, checks that a value has been entered
  • Type, checks that the data is the right type
  • Range, checks that the data is within an acceptable limit
  • Format, checks that the data is in the correct format
  • Consistency, comparison between different entries
  • Reasonableness, checks that the details are plausible
• Types of test for software solutions

  • Usability testing is undetaken when researchers observe how individuals complete tasks with the software. Formal testing is conducted in a lab with proper equipment, while informal is not.
  • Test data, includes trace tables that compares the actual output answer with expected outputs provided by the tester.
• System requirements are the minimum hardware and software required for an app to run.

  • Functional requirements, define what the system should do
  • Non-functional requirements, define how the system performs its functions
• Types of non-functional requires:

  • Usability: The system should be easy to navigate for users
  • Reliability: The system must be available and handle most errors
  • Performance: Pages should load quickly under normal internet
  • Security: Client data should be stored and transmitted securely using encryption
  • Portability: The software should be ran on other operating systems
  • Maintainability: Should be able to faciliate updates and maintaince
  • Affordance: Design elements that intuitively indicate how the software is used.
  • Compliance: Compliance with laws and ethics
• • Version control keeps track of changes made to a file, so that it can be rolled back to a previous version when needed.
  • Backing up a file is creating a copy of the file and storing within a cloud or physical location and occurs periodically.
