Below are a number of steps that need to be done in the SDLC.
Number them in order and state whether each is part of the Planning, Analysis, Design or
Development, Implementation or operations phase.
10 The program design is developed.

the analysts, and models of the system.
8 Logical models are created
9 Physical models are created
3 Identify the scope and boundary of the project
7 A change management policy is created
15 The users are trained
5 A system design specification is written
2 The requirements are gathered using interviews, questionnaires and other
techniques.
6 A conversion plan is prepared
11 User interfaces are designed
16 The new system is built and tested.
12 The architecture design and interface design are developed.
13 The database specifications are developed.

Exercise 3 – System Development Methodologies
Suppose you are an analyst for the Roanoke Software Consulting Company (RSCC), a large
consulting firm with offices around the world. The company wants to build a new knowledge
management system that can identify and track the expertise of the individual consultants
anywhere in the world based on their education and the various consulting projects on which
they have worked. Assume that this is a new idea that has never before been attempted in
RSCC or elsewhere. RSCC has an international network, but the offices of each country may
use somewhat different hardware and software. RSCC management wants the system up and
running within a year.
Question
What type of methodology approach would you recommend that RSCC use? Why?
The development and learning process for developers and various offices needs to be
considered, as this is a new information management system that has not yet been tested. A
large number of users will be hesitant and unsure of how the system is being developed.
Second, because offices can use a variety of hardware and software methods they will need to
be developed to obtain specific information on a simplified version of the system to gain a
better understanding of what it does and how it works. After carefully analyzing the system
requirements SRCC Company will need, I recommend the System Prototyping method as this
method is faster and more efficient compared to other methods and will allow different
offices in each country to test system prototypes in the early stages of the SDLC. Several
models can be developed and tested at different offices to get the user's response quickly to
rebuild this prototype in the hope of achieving high efficiency. Each time a prototype is
rebuilt an engineer will add additional features to gain a better understanding of what each
office needs. Once the prototypes are redesigned to suit the needs of each office, they will be
used to build a comprehensive system that meets the needs of all global offices within a
single system.
The prototyping of the system will allow for intermediate communication between the
various offices and developers to quickly determine which type of system will suit the needs
of all offices with just one system. Because the system has never been tried by any other
company, it is in the interest of all stakeholders to understand and provide feedback in order
to improve the efficiency of a single system that needs to be built.
