4.13 Systematic approach to problem solving

Question 1

what is the order of stages in software development

Answer 1

analysis, design, implementation, testing and evaluation

Question 2

what is the analysis stage

Answer 2

it is defining a problem and the requirements of the systems that solves the problem must be established and a data model created - requirements of system must be established by interaction with intended users

Question 3

what is the design stage

Answer 3

before constructing a solution it must be designed eg planning data structure for the data model, designing algorithms, designing an appropriate modular structure for the solution and designing the human user interface - involving prototyping

Question 4

what is the implementation stage

Answer 4

models and algorithms must be implemented in the form of data structures and code that computers can understand

Question 5

what is the testing stage

Answer 5

implementation must be tested for the presence of errors, using selected test data covering normal/typical, boundary and erroneous data

Question 6

what is the evaluation stage

Answer 6

The criteria for evaluating a computer system include speed, cost, reliability, portability, power consumption, and capacity. These factors help determine how well a system meets user needs.
