Problem
definition
What
is the daily time required to create my week 6, 16, 26 Blogs?. I’m here
applying the Learning Curve Theory in a reference to my W1, 2, 3, 4 blog, so I
can predict how it will take me for my W6, W16, W26 blog posting?. This
exercise was done before in my previous class, however here I update it and
modified it to my current blogs activates.
Development
of the feasible alternatives
A.
Time for W6
B.
Time for W16
C.
Time for W26
Develop
the outcomes for each alternative
How much time would
be required to produce all the W6, W, 16, & W26 Blogs, in general learning
Curve will generate several key benefits as follows:
-Improved capacity planning
-Improved capacity planning
-Improved
Costing
-Changes
in Product/Process Design
Accepted
Criteria
The
learning curve is an analytical tool that can be used to estimate the rate at
which cumulative experience allows workers to do tasks faster and with less
cost. Operations managers use learning
curves to estimate how much the repetitions of a task will enable them to
reduce the amount of resources required to accomplish the task. A learning curve is defined by an equation
that contains the rate of improvement (i.e., reduction in costs or reduction in
time taken) in performing a task as a function of the cumulative repetitions of
the task.
As
the conclusion of my blog per the best case worst case, most likely scenario
graph, taking a percentage of 90% as the most likely case, I shall spent not
less than 120 min on daily basis to do a quality blog. This amount will be the
base of the calculation of this analysis, considering that 120 min is the
average daily rate needed to create my first blog “W1”, with a 90% improvement
or (learning rate). This analysis will use the spread sheet analysis.

Selection
of the preferred alternatives
As
per the best Learning Curve Theory shown in the above graph, assuming 90%
learning curve, it’s indicated that I will need about 91.39 min/daily to complete the Blog of
Week 6 and 78.73 min
for Blog of Week 16 and finally 73.13 min for Blog of Week 26.
Performance
monitoring and the post evaluation of results
I
will continue monitor the time needed to create such a good blog, so I can determine
if it’s matching my analysis or not.
Conclusion
The
learning Curve theory, gives a clear prediction to what time needed to perform
a task. In my case above that I will need about 91.39 min/daily to complete the Blog of
Week 6 and 78.73 min
for Blog of Week 16 and finally 73.13 min for Blog of Week 26.

Excellent posting, Mohammed!!!
ReplyDeleteAnd I am confident you will appreciate having done this assignment when you go to take your CCC/E and possibly your CEP or PSP, as learning curve theory is a favorite topic for AACE and it applies to both cost estimating and scheduling.
Keep up the good work, but I really need to be seeing your paper...... You have dropped way behind on that....
