Answer 6
Correct Choice: A
Explanation:
The organization’s reputation being at stake, the threshold for such a risk would be very low.
Mitigation plan against an environmental contamination would mean reducing the impact, which may not be a plausible response.
Procuring an insurance against the risk would only transfer the monetary impact of the risk, and not the intangible impact like, the reputation of the organization.
Planning precautions against the occurrence would still leave an opportunity of occurrence. This cannot be completely avoided.
The best option would be to drop the approach – that is, complete avoidance of the risk.
Answer 7
Correct Choice: B
Explanation:
Choice B is the correct answer.
The critical path is the longest duration path through a network and determines the shortest time to complete the project. The PERT estimates of the tasks listed are 27, 22.5 & 26. Therefore, the length of the critical path of the project is 27+22.5+26 = 75.5.
The standard deviations of the estimates of the three tasks are determined as (P-O)/6 = 5.33, 3.83 & 2.67 respectively. The standard deviation of the total path is determined as Sq. root (sum of variances), where variance = square of standard deviation.
***See the table at the bottom of this page***
Hence, standard deviation of critical path = Sq. root (28.44+14.69+7.11) = 7.09.
Hence choice B is correct while choices A, C and D are incorrect.
Answer 8
Correct Choice: D
Explanation:
Determining validity of quality standards, followed by the project is a ‘quality assurance’ activity.
Compliance of work results to required specifications is a ‘quality control’ activity.
Determining quality standards is a ‘quality planning’ activity.
‘Checking adherence to processes’ is a quality audit activity to ensure that standard operating procedures or job instruction documents (SOPs or JIDs) are being followed for producing the deliverables of the process.
Answer 9
Correct Choice: D
Explanation:
Individual development (managerial and technical) is the foundation of a team.
Answer 10
Correct Choice: A
Explanation:
A Project plan is the basis of project plan execution and is a primary input.
Work authorization system is a tool used for orchestrating execution of various project tasks.
Whereas, Corrective and Preventive actions are inputs to the project plan execution process from various controlling processes.
