 All of the following values are coming from the empirical data and interviews with the tech lead and tester who estimated the current effectiveness of the team as follows:
 #Half of the tasks due to the blank in the knowledge of the business logic and code clearance best practices have to be revised
 #A rough estimation of 10 % probability of mistakes at the Testing stage was done
 #Preparation of the release was estimated for 0.5MD (the estimation is reliable because the Techlead considered this task as his routine activity)

 For the effective process of analysis and prioritization, the product owner collects several requests all at once and during meetings with the analyst explains the tasks for further specification.

 The time spent on analysis Exp (1) days for the batch from the Product owner was derived from the average time based on the usual process when the Analyst and Product owner have a 1to1 and the other day assigns the tasks to the team members.

 For both of the generators, the author used the presumption of Poisson distribution 5 requests/day and 2 bugs/day that was transformed into Exponential distribution Exp(1.6) an Exp(4.0) respectively (with the time unit Hour). This estimation was done based on the data from 5.10.2020 - 2.1.2020 (90 calendar days) exported from Jira. The data had to be cleaned due to incoming requests on non-business days, statistical outliers ( days when somebody created a number of irrelevant to this model sub-issues or migrated a number of issues from the old backlog). From the cleaned data we can derive that the average and the variance of the final set of data are close enough, which were used as a hit to suppose that the distribution of this value could be considered to be Poisson distribution.
