IS-approach to problem solving à Systems Analysis & Design (Figure 9.2)

Systems analysis

1.Problem analysis (what)

2.Information gathering (where & why) (Table 9.1)

3.Decision making (how) (Figure 9.7)

Systems design (Input, Process, Output, Procedures & Control)

1.Logical design (describe what system will do/functional requirements) (Figure 9.9)

2.Physical design (how the system will work/physical requirements) (Figure 9.10)

3.Implementation (coding, testing, training)
