Defining the problem

Identifying the problem

Needs of the client

• A need is an instance in which a neccisity or want exists
• Solution needs to meet the requirements of these needs

Functionality Requirements

• Describe what the system will do & what the solution needs to achieve
• The requirements of the system give direction to the project
• Requirements are defined as features, properties and behaviours a system nust have to achieve its purpose

Compapatibility Issues

• Software of various types runs on a variety of enviroments
• When designing software developers must ensure products are able to be used on multiple devices and conditions
• Examples include:
  • Problems with different operating systems versions
  • Browsers that do not implement HTML standards
  • Hardware not supporting software

Performance Issues

• Testing and real world applications are very different
• Testing must be extremely rigourous and broad
• Common Issues include:
  • Appearaning to be not repsonding when time takes too long
  • Poor Response times in networking operations

Boundaries of the problem

• Boundaries of the problem define the limits of the problem of the system to be developed
• Anything outside the system is said to be part of the enviroment
• The system connects with the enviroment through an interface
• Determing the boundaries effectively determines the system and how the enivroment interacts with it
