Introduction
Adroit Ads is a London based advertising agency which is created commercials
advertisements such as video, poster, and short film. Adroit Ads want to award of the best
advert companies. In the Adroit Ads Company, the creative team handles all activities of the
company. Here, I will be developed system application for Adroit Ads.
The report is divided by into three sections. The first section will be explained SDLC life
cycle and various type of Model. The second section will be described FSR report and their
components. The third section will be included the user and system requirement with
documentation.

LO1 Understand different systems life cycles
1.1 Evaluate different systems lifecycle models
What is SDLC?
System Development Life Cycle is a procedure that developed a system with low price and
high quality in the shortest time. It is also included the process of development, maintain,
modify and upgrade the system or software. It develops only software, only hardware, and
combine a form of both which fulfill the client need (Alwan, 2015).
SDLC have planning, building, design, testing, defining and deployment stage. SDLC Model
type
 Waterfall Model
 Spiral Model
 Agile Model
Figure 1: SDLC Lifecycle
Rapid Applications Design (RAD) Model: RAD is combined form of iterative development
and prototyping model that is no need more planning. It writes software according to
4

planning phase which is a need for developing the product. It focuses on customer need
which is collected from workshops and group (Daassnet, 2015).
Advantages:
 RAD is decreased the development time and Iteration time due to powerful RAD
tools.
 RAD is getting reviews initial stage which is encouraged the developer.
 It rises reusability of system components.
 It also solves integration issues in the beginning stage.
 RAD can be measured the Progress.
Disadvantages:
 It only works for small development times.
 It is a modularized system which is built on RAD.
 RAD system is depended on modeling skills and user interaction.
 It needs experienced developers/designers.
 RAD Management complexity is high.

Spiral Model: Spiral Model is combined form of iterative development and water model.
Spiral model has four phases such as Identification, Design, Construct or Build, and
Evaluation & Risk Analysis (Boehm, 1988).
Advantages:
