Part-II – True or False Questions
[20 Questions – Each question carry 1 mark]
S. No
Question
True/False
1
System requirements are communicated through a collection of design documents and physical processes and data models.
2
The decision to make, to buy, or to outsource influences the design tasks that are performed throughout the rest of the design phase.
3
CASE repository entries are updated to reflect specific technology decisions as they are made.
4
There is absolutely no need for designing a custom system since there are already so many pre-packaged systems available to any company regardless of its size.
5
Highly skilled IS Professionals are easy to hire and retain.
6
Letting technology drive a business can be dangerous.
7
The key challenge in systems integration is avoiding a system wide crash upon installation of legacy software.
8
Outsourcing firms called Application Software Providers (ASPs) supply software applications and/or software related services through the Internet.
9
Time and arrangements deals are potentially more expensive if the service provider requires unforeseen resources to complete the project on time.
10
A common need to the business should be satisfied by contracting with an Application Service Provider (ASP).
11
The only skills that are applied during systems projects are technical.
12
The score column in the Alternative Matrix represents how easily specific criteria are met by the alternative.
13
The concept that says the same message can be interpreted differently by different classes of objects is called ‘encapsulation’.
14
Classes inherit the attributes and methods from the subclasses underneath them
15
Methods implement an object’s behavior
16
Dave has a concrete object called ‘Student’. Specific students like: Mike Macli, Jeff Le, Karolyn Maloney would be considered as instances (or objects) of the ‘student’ class
17
An object is an attribute of an instantiation
18
Object-Oriented systems focus on capturing the structure and behavior of the information system in little modules (known as objects) that encompass both data and processes
19
The Object-Oriented Approach is considered as an ‘exciting enhancement to systems analysis and design’
20
Actual techniques and approaches that analysts and developers use have remained largely unchanged over time

Explanation / Answer
When a system is designing, it is important to analysis the organization’s or business environment and its requirements deeply. Analysis is the second phase of SDLC. In this phase, analysts make analysis on the business needs. Therefore, in the SDLC, business needs or requirements are determined in the analysis phase
Hence the correct option is “The analysis phase”
In the design of the physical architecture layer, necessary hardware and software components are determined and these specifications are documented as Hardware and Software Specification
Hence the correct option is ”Hardware and Software Specification”
Before designing a system, it is required that document how the current system takes input, processes it and outputs the result. Blueprint is a logical model of the present system. Blueprint helps to understand the information flow in the system.
Hence the correct option is “Blueprint”
The system design order is system specification, Weighted Alternative Matrix, Interface Design, Physical Data Model, Data Storage Design
Hence the correct option is “System Acquisition Weighted Alternative Matrix, Interface Design, Physical Data Model Data Storage Design”
There are four ways of recommended approaches to develop a new system:
1) Standard SDLC
2) Prototyping
3) Rapid Application Development (RAD)
4) BPR
Hence the correct option is “4”
Hence the correct option is “A and B”
System integration is nothing but combining sub systems such as packaged software, existing legacy systems, and new software which is written such that these all function together.
Hence the correct option is “Combining packaged software, the legacy system and new software”
Hence the correct option is “Rocket control software for NASA”
Outsourcing is nothing but purchasing goods or hiring services form third party.
Hence the correct option is “A, B and C”
Hence the correct option is “The decision to outsource is strategic”
