Dear friends, 

Please take a shot at these ... My answers didn't match with the source and I am not quite convinced with their answers and explanations...

 

Hoping to get some input and clarification here from brilliant minds.

 

1. One phase is planned at any given time and the planning for the next is carried out as work progresses on the current phase and deliverables. Which of the following correctly defines the above text?

a. Overlapping relationship

b. Sequential relationship

c. Multi-phase relationship

d. Iterative relationship

 

2. Which of the following statements is true about control charts ?

 

a. Special causes are easier to predict and handle than common causes

b. Common causes are easier to predict and handle than Special causes

c. A process is stable if it has only special causes

d. None of the above

 

3. A project manager wants to measure project performance against the project baseline. Which of the following techniques would be MOST helpful?

 

a. Variance Analysis

b. Earned Value Technique.

c. Work Performance Measurements

d. Reserve Analysis

question one :- right from horses mouth - page 22 PMBOK - I thought it was option 1 - but cant supersede PMBOK.

1)


Iteration means executing one phase while planning the next. so pick the right answer now based on this bold sentence shown


**************************************************************


2)


Common Cause:


In a constant-cause system the variations in a measured variable are considered due to chance and to remain in the system unless the process is itself altered. Such causes are referred to as
common causes.


Examples of Common Causes:
• Variations in environmental variables such as temperature and humidity
• Variations among machines
• Variations among worker’s skills
• Variations in raw materials


Overreacting to common-cause variation usually leads to “tampering” with a process
that may already be in control.This in turn leads to increased variation in process results
****************************************************************************************************************


Special Cause:


The variation observed is considered to be the effect of many, individually small, unobserved influences.


Special causes are individually important and affect process results only some of the time.
They arise because of special circumstances


On the other hand, failing to detect and deal with special causes means a lost opportunity
to eliminate variation in the process


Examples of Special Causes:
• Temporary change to a new supplier
• Temporary worker not properly trained
• Intermittent power failure
• Ice storm
• Bird in the toothpaste vat


 


A process is considered to be in control (or stable) if only common causes are operable
and no special causes are influencing the variability of process results

Variance analysis...

1 - d

2 - a

3 - b

infact for question no 3 type questions always confuses as: Variance analysis is done as part of Earned Value Technique.

@barora - Please lemme know the Correct Answers.

 Hey Humanbeing... you are all set.

1. For the first one ... I am still not convinced. To me two things going on at the same time and in parallel is overlapping. Iteration would be ..proceeding and progressing in loops like a spiral model. Anyways.... PMBOK rules at the end of the day.

2. For the second one .... the question asks for "Predicting" not "Determining".

An event that might happen to throw the process out of control and is not coming from the process itself ... how on this Earth can some one tell that an external factor would hit the process and what it would be ..it is like the unknown unknown....on the other hand if we are talking about one of the factors of the process causing the out-of-control situation... that can still be predicted using various analyses...coz we already know what factors are in play and which ones is the process more sensitive to (using DOE).

3. For the third one... Variance analysis does look at SV and CV with reference to the schedule and cost baselines and these values are reported in Work Performance measurments to show Project performace. So I don't understand what is missing in the Variance Analysis that Earned Value Technique has ... Earned Value technique uses the same parameters for calculations (EV, PV and AC to calculate SV, CV, SPI and CPI)...if it had asked for forecasting as well..then I could understand that EVT was more appropriate. But the question only asked for Project Performance only.

 

Anyways ...overall I think I am going to have some rough time passing this exam.
