How difficult? I show an example below to illustrate how difficult it is
, and also this example is related to Bayesian probability for your calculation if you are interested in
.
IT implemented a new system or performed a system modification due to business needs.
There will be 2 scenarios, 1st is implemented the system successfully in view of meeting the user requirements, project timeframe and budget, or another scenario is project failure including not fit to user requirement, overbudget, project delay. We simply put the probability for each scenario as 50%.
And also there will be another 2 scenarios for business using or not using the system, Business performed good and met the target or Business performed poorly due to not meeting the target or even suffering a loss. Again we simply put the probability of each scenario as 50%.
For good system and good business, Business users may have the responses of (1) appreciating IT's work or, (2) ignoring IT's work or, (3) complaining IT. For each response, the probability is 33% for simplicity.
For good system and bad business, Business users may have the responses of (1) ignoring IT's work or, (2) complaining IT. For each response, the probability is 50% for simplicity.
For bad system and good business, Business users may have the responses of (1) ignoring IT's work or, (2) complaining IT. For each response, the probability is 50% for simplicity.
For bad system and bad business, Business users may have the responses of (1) ignoring IT's work or, (2) complaining IT. For each response, the probability is 50% for simplicity.
Now the questions are:
What is the probability of IT's work being appreciated
?
What is the probability of IT's work being ignored
?
What is the probability of IT's work being blamed or complained
?
