 80% of the effort is in the last 20% of the implementation

 “adding people to a late project makes it more late”

 “Requirements always change…”

 “Customers/Users never know what they want”

 “70% of successfully acquired systems are never used or not used to the extent expected”

 “20% of the planned schedule is allocated for testing yet 50% is actually used”

 “Cost, schedule, quality: pick any two”

Requirements Determination

Trang 30

 what the system must do?

 what characteristic it must have?

Trang 31

 Document analysis

Trang 32

Functional vs Non-functional

 Functional requirements describe system services or functions

 specific behavior or function

 a set of inputs, the behavior, and outputs

 Non-functional requirements are constraints on the system or the development process

 "quality attributes" of a system

Trang 33

2018

Nonfunctional Requirements

Operational • The system should be able to fit in a pocket or purse

• The system should be able to integrate with the existing inventory system.

Performance • Any interaction between the user and the system

should not exceed 2 seconds.

• The system should receive updated inventory information every 15 minutes.

Security • Only direct managers can see personnel records of

staff

• Customers can see their order history only during business hours.

Cultural & Political • The system should be able to distinguish between

United States and European currency

• The system shall comply with insurance industry standards.
