Question 4 What is the difference between systems prototyping and throwaway prototyping methodologies? – a functional system 5’ – understanding the user requirements and design considerations more quickly 5’ © Copyright 2011 John Wiley & Sons, Inc.
System Prototyping Throwaway Prototyping Thorough analysis 2’ Throwaway /refine 1’ 2’ Quick 2’ Dirty 2’ Evolve into final system 1’
Question 4 Throwaway prototyping – With unfamiliar technology 2’ – Complex system 2’ – Reliable system 2’ System prototyping – Short time schedule 2’ – Schedule visibility 2’ © Copyright 2011 John Wiley & Sons, Inc.
Question 5 What are the main differences between the Waterfall Development and the Rapid Application Development methodologies? RAD emerge in response to the weakness of waterfall – With unclear user requirement 2.5’ – With unfamiliar technology 2.5’ – With short time schedule 2.5’ – With schedule visibility 2.5’ © Copyright 2011 John Wiley & Sons, Inc.
Question 6 Explain functional and non-functional requirements and give 2 examples in each case for a bank ATM system. Functional requirements – what the software should do 2’/ processes 1’ + information 1’ – Example 1: allow users to check their balance – Example 2: include real-time balance Non-functional requirements – characteristics the system should have 4’/ operational 1’ + performance 1’ + security 1’ + cultural and political requirements 1’ – Example 1: finish any user operation in 10 seconds – Example 2:include all possible safeguards from viruses © Copyright 2011 John Wiley & Sons, Inc.
