Project execution, monitoring and control

Question 1

Design o~en follows an evolutionary, trial-and-error process composed of two Interrelated
activities. Describe each of these activities and comment on the interrelated nature of the
activities. [10]

Answer 1

The design process is composed of two interrelated activities. First is
preparation of a functional design that shows the system components and their
relationships. The purpose of this design activity is to determine the logical,
functional elements of the system and how they should be interconnected to
achieve the system’s objectives. This is the thrust of systems engineering
(Chapter 2) and system definition/FEL-3 (Chapter 4).
See Chapter 2 and Chapter 4
Second is preparation of a physical design that shows what the actual system
and its components will look like—their sizes, shapes, and relative positioning.
This design activity results in engineering, manufacturing, architectural, and
other types of drawings and models that show the details necessary to later
fabricate, assemble, and maintain the system. This design activity sometimes
reveals places where the functional design is impractical or infeasible because of
assembly, maintenance, or appearance considerations, in which case it must be
redone

Question 2

a) Describe the project execution phase and what it includes.
b) In what stage does execution happen?

Answer 2

Detail design Elements and configurations of the system are defined and specifications are converted to plans,
sketches and drawings
Ensure System’s components individually and collectively provide the functionality necessary to satisfy the system’s performance requirements
Prepare for physical design that represents what the actual system and its components will look like and be made of
Production Build System is physically built either as single unit or mass produced
System fabrication begins as soon as design work has been sufficiently completed
Project Manager and manager for manufacturing monitor, inspect and document progress, comparing planned versus actual results,
which may lead
to corrective action
continuously perform tests on components, sub-systems and final end-item to ensure it conforms to requirements
ImplementationThe system is installed and integrated into the user’s environment
User training is required to inform user how to operate ,
maintain, and service the system
User Acceptance training is needed to determine if the system can be adopted or installed as is,
or needs modifications
System isinstalled either Parallel installation , Pilot operation or cold turkey
After end-item is installed, terminating the project in a planned and systematic manner.
