Task 1: System Development Methodology
This section of the report will be identifying the system development methodology that
can be employed for designing a software system. This section of the report will be comparing
two methods of software implementation, which are modified waterfall model and extreme
programming.
1.1. Description of Both the Model
The following section provides a brief description of Modified waterfall model and
extreme programming.
1.1.1. Modified Waterfall Model
Modified waterfall model is an advanced version of the traditional waterfall model and
therefore, make use of almost similar phases as that of the pure waterfall model. A modified
waterfall model solves a number of problem that is faced by the traditional waterfall model
(Datyal 2015). The traditional waterfall model was gradually becoming redundant due to its
limitations. The modified waterfall model helps in eliminating those limitations. The phases of
modified waterfall model is indicated in the figure below-

One of the most basis advantage of modified waterfall model is that it is quite flexible in
comparison to the traditional waterfall model.
1.1.2. Extreme Programming
Extreme Programming (XP), is an agile software development framework or process.
This particular software development method aims in producing a software of high quality
(Salah, Paige and Cairns 2014). Thus, this framework is mainly used to improve the quality and
