15% CHANCE, YOU WILL EXCEED THE ESTIMATE


Question on Mean

This is a question from Rita fast track.
You just completed a cost estimate on the project, and you are assuming that there is a 15% chance you will exceed this estimate. You are:
a Below the mean
b. Above the mean
c. Above the median
d. Below the median

Hence answer will be B above the mean

DIFFERENT PROBABILITY DISTRIBUTION METHODS


ONE QUESTION IN PMZILLA - THESE ARE OPTIONS A, B, C AND D.

Q Which one is Uniform distribution method 

( http://pmzilla.com/q-framed-me-pmbok#comment-20007 )

Q
Which one is Uniform Distribution Method graph


 

ANS

A = WEIGHTED AVERAGE BETA DISTRIBUTION
B = NORMAL DISTRIBUTION
C = UNIFORM DISTRIBUTION
D = TRIANGULAR DISTRIBUTION

Why bell shape of normal distribution curve:
NORMAL DISTRIBUTION
To know how bell shape curve formed?
Will explain this example:
you are checking 1000 tests given by pmp aspirants.
your standard value of profeciency is suppose 150 out of 200
this standard value 150 will be called as MEAN value.
now you observe that --- some students are performing better than this , some are below this.
then you make a table of marks at X axis against frequency of students obtaining that marks at Y axis

Values = Marks at X axis
Frequency =Nos of students at Y axis
100
30
110
45
120
100
130

135

130

125
180

Total
1000

there are many cases where the data tends to be around a central value with no bias left or right, and it gets close to a "Normal Distribution" like this:

PHASE TO PHASE RELATIONSHIPS

I find in PMBOK these 2 terms of classified but not explained clearly, based on her inputs I tried here to elaborate it more:

PHASE TO PHASE RELATIONSHIPS

Iterative
Overlapping



1
since work by nature and outcomes remains same, though
scope, schedule, cost, place,
 contracts changes, and its successive phases becomes undefined and varying to any extend.
its phases are not similar in their nature and outcomes and they are linked in a sequence and dependent like sequential phases but unlike starting of second after one, it can overlap,
2
one phase is planned and executed,
when 1st phase in execution 2nd phase is planned.
here since phases are entirely different in nature hence they can be either planned earlier or later
3
staff, vendors and workforce may repeated same as nature of work remains same.
Staff , vender, workforce will change
as per the change in nature of work
4
Example :  research program , there is no clarity for next phase.
why it is iterative , because, research, research research -------its repetition.
Here next phase planning much depend on,
further scope as per results of 1st phase.
for example, construction may
begin when quarter design work completed.
Concept - design- construct -testing -
these are the phases and can be overlapped but not similar in nature. Here you can plan in advance or later

LAG AND LEAD QUESTION




Question: You are in the process developing a project schedule for repainting your house. In order to repaint your house, you first need to scrape off the existing paint, and then add a layer of primer. The primer provides the paint a better
bonding surface so it sticks to the base material much better. Without priming, drywall surfaces will soak up more finish paint in some areas than in others, producing a splotchy effect.
You decided to speed up the process by starting priming before all the scraping is finished. However, once the primer is applied, you must wait until the primer dries before adding on the actual paint. You estimate that it will take 8 hours for the primer to dry. To correctly sequence these activities, which of the following should you do?


(A) Add a lead time to the priming task with respect to scraping, and a lag time to the priming task with respect to
painting
(B) Add a lead time to the priming task with respect to scraping, and a lead time to the priming task with respect
to painting
(C) Add a lag time to the priming task with respect to scraping, and a lead time to the priming task with respect to
painting
(D) Add a lag time to the priming task with respect to scraping, and a lag time to the priming task with respect to
painting
----------------------------


Q: Activity A has a finish - to-finish relationship with activity B. Activity A has a
duration of 10 days. Activity B has duration of 9 days with a 3 day lag. what is the total
duration of activity a and B?
1.  7 days
2.  8 days
3.  12 days
4.  9 days
Correct answer would be 13 days.
FF+3
In above case
Bigger one Duration +LAG 
Total duration of A and B activities = 10+3
 In this case 
Suppose project starts by 6th of March 
We will demonstrate it
by Zero start method like this
9
18
B/9

(Start of project by 6th March) 5
FF+3
15

A/10


Project is finishing on 18.
Thus 6th March morning to 18th March evening = 18-5 = 13 days
 -------------------------
Question
 What is total duration of A and B activities?
B/11

FF-2

A/10

Suppose project finishes on 15th March.
By question - activity A will finish 2 days later than B. because activity B is taking 2days lead.
By zero start method we can illustrate it like this:
Here activity B has to start 1st
2
13
B/11

FF-2
5
15

A/10

By this presentation it is clear that project has to be started by activity B on 3rd of March to get finish on
March 15th.
Thus duration of project will be = 3rd to 15th = 15-2 = 13 days.
 What is total duration of below activities?
B/11

FF-2

A/10

Solution
Zero start method
5
16
B/11

FF-2

A/10



16-4=12 days
