Agile and Adaptive Methodologies - ASD

This article discusses Agile and Adaptive Methodologies with a focus on Adaptive Software Development (ASD). It explains the phases of ASD and its advantages and disadvantages. The article is based on the System Development Life Cycle (SDLC) process and is relevant for students studying ASD or software development.

Introduction
System development Life Cycles (SDLC) is termed to be a process that is standard and that is
followed by an individual or an organization in conducting all the necessary steps in analyzing,
designing, implementing and maintaining the proposed information system. Agile is one of the
methodology that is used for developing and improving the system (Hoffer.H., 2006). The idea
in this assignment is discussing the agile methodologies and the specific techniques associated.
Agile Methodologies.
These are methodologies used in developing arena of a system. This methodology has evolved
from waterfall method solving all the cases of being bureaucratic, inflexibility and slow (Qumer.,
2007). This has led to definition of an agile as a methodology that has anticipated the need to be
flexible and applying a very high level of pragmatism in delivering the finished products (Rouse,
2017). Agile method is one of the software development where people focuses in
communications, very flexible, encourages very rapid and iterative developments of all the
products in small releases, lean, and it is very responsive.

Adaptive Software Development (ASD)
Adaptive Software Development (ASD)

In this case the idea is explaining the adaptive software methodologies. ASD is a process of of
software development that has grew out from RAD (Van de Vyer., 2003). It has embodied the
principles that continually adapts the work process at hands in the normal state of the affairs. It is
divided in four phases as shown in the diagram below.
Figure 2 four phases of ASD
1. Communication and Planning- this is the feasibility study and risk assessment
preparations
2. Analysis- approving the quality of the software by the approving it through the
documentation. We need a software requirement analysis in doing this phase.
3. Design and Development- using the prototype approach by verifying the requirements
design
4. Testing and Development- testing the cases for each increment as prepared at the first
phase.
Advantages of ASD
1. One can make a discussion
2. Getting ideas
3. Making demonstrations
4. Able to maintain the good quality of the work
Disadvantages of ASD
1. It is time consuming
2. It may require a lot of labor which may be costly and hence sometimes not effective
