Problems with using Lines of Code to measure the size of a product include(s) (a)   The creation of source code is only part of the development effort (b)   The Lines of Code (LOC) will differ between languages and cannot be measured for some languages (c)   Should comments, data definitions etc (i.e. non-executable LOC) be included as well? (d)   The final size (kLOC) can only be determined once the product is delivered (e)   All of the above. 23.

The advantage of following the IEEE Standard for drawing up a Software Project Management Plan (SPMP) - see IEEE Standard 1059.1 1987 - is (a)   It is drawn up by representatives from major software development organisations (b)   It is designed for all types of software products (c)   It is a framework that can be used irrespective of process model or specific techniques (d)   It can be tailored for each organisation for a particular application area, development team or technique. (e)   All of the above. 27. The best way to test the Software Project Management Plan (SPMP) is by (a)  Prototyping         (b)  Inspection           (c)  Simulation         (d)  Compilation         (e)  Debugging. 28. Algorithmic cost estimation in different organisations may be different for the same application development, because (a)   Different organisations consider complexity factors differently (b)   Different organisations may use different programming languages (c)   Developers' skills may vary (d)   Techniques for the measurement of productivity may vary (e)   All of the above may be true. 29.

Object-oriented concepts are not new. The first OO language was considered to be (a)  ALGOL-68                                         (b)  FORTRAN 77      (c)  C                      (d)  MODULA                                          (e)  SIMULA 67.

Answers

21.	Answer : (a) Reason:  Internal costs comprise all the costs to the developers.
22.	Answer : (e) Reason:  There are many problems with using Lines of Code to measure the size of a product.
23.	Answer : (d) Reason:  Software Science bases its estimation of the size of a product on the number of operands and operators.
24.	Answer : (a) Reason:  In Intermediate COCOMO there are three modes: organic, semidetached and imbedded.
25.	Answer : (b) Reason:  Work that continues throughout the project and does not relate to any specific phase of software development is termed a project function.
26.	Answer : (e) Reason:  There are many advantages of using a standard.
27.	Answer : (b) Reason:  The best way to test the Software Project Management Plan (SPMP) is by a plan inspection by the SQA team. In order to further reduce risk the duration and cost estimates should further be independently computed by people other than the original project team.
28.	Answer : (e) Reason:  Cost estimation incorporates a number of factors.
29.	Answer : (e) Reason:  The aim of software engineering is to produce software that is fault-free, delivered on time, delivered within budget, and satisfies users' needs.
30.	Answer : (e) Reason:  The first OO language was considered to be SIMULA 67.
