As we continue the discussion on the information technology perspective, let us look at the methodologies used in this perspective.
The methodologies used in the information technology organizations differ though they usually fall into two approaches, which are:
• Predictive: this approach uses structured processes which places emphasis on planning and formal documentation of the processes which are used to complete the change. Each stage of the process is completed before moving on to the next stage.
• Adaptive: in this approach, extra time is built in for rework. Most adaptive models are both gradual and repetitive and they focus on the growing product in both their span and extent.
A hybrid methodology can also be used which is a combination of both approaches. A hybrid can include a complete vision for the whole initiative i.e. the predictive approach, as well as a description of the details within individual cycles i.e. the adaptive approach.
Here is a list of several methodologies or approaches that a business analyst working in the information technology environment may come across.
No. | Methodology | Brief Description |
| 1 | Homegrown or Organization Specific | This methodology is taken from elements of other traditional methodologies may be created by an information technology organization in order to govern information technology-based initiatives. |
| 2 | Requirements Engineering (RE) | This is a structured approach for requirements development and management and it is used in predictive, adaptive, and agile environments. |
| 3 | Structured Systems Analysis and Design Method (SSADM) | This predictive development methodology is focused on traditional logical modelling techniques. |
| 4 | Unified Process (UP) | In this adaptive development approach, the business analysts are usually only involved in the inception and elaboration stages of the process. |
