If a group is 88% successful in completing all assigned tasks with 24 employees, is there a way to guesstimate the success rate percentage if you add 6 additional employees (assuming all other factors such as production/skill/etc are equal)? Thanks.

The percentage will be the same assuming all other factors equal.

I'm getting at workload. If they can achieve 88% success with 24 employees (assuming they can only work a fixed amount of hours per day), how much with the decreased workload and additional help affect the success rate.

.88 x (24+6) = 26.4 successful employees out of 30

Is it as simple as saying each employee contributes x percentage of success so 6 additional employees would result in a combined XX percentage of success?

Let me try again.

There were 133 projects last year with 24 employees working on them. The group was able to achieve an 88% completion rate.

How can I compute the completion rate if there had been 30 employees (all other factors being equal) with the same 133 projects.

24 employees completed 117 projects equaling 4.875 completed projects per employee.

If you had 30 employees with the same rate you would have completed 146 projects.

RedYote was right with 110%

so for this you have 133/24 that gives you 5.54 per person.

the 88% is not needed for what you are asking

so 5.54 per person and you add 6 more you get 33.25 so you would be able to solve 33 more cases in a year

This is what I get... 24 employees working on 133 projects and completed 88% of them. So 88% of 133 is 117. Each employee did 4.876 %. There were 16 projects that didnt get done, so if you add 3.2 employees with each doing 4.86% (like the others), you should be able to get 100% completion...........maybe

Unless your achievements are directly proportional to effort with no outside influences (like assembling Ikea furniture or consuming jelly donuts), you cannot use a simple calculation. Sounds like you need some sort of statistical analysis, with variable inputs and simulated outputs. I occasionally use software (based on Monte Carlo simulations) to evaluate risks and calculate contingencies, but the extent of my understanding is the inputs and outputs. The calculations taking place in the background are beyond my comprehension, but probably exciting stuff for a nerdy statistician.

Are your 6 new guys as experienced/knowledgeable/goal oriented as the original 24 guys? If you have to bring the 6 up a “ learning curve “ then your completions will NOT be a steady increase.

This

133*0.88 = 117.04 projects completed
117.04/24 = 4.876 projects/employee completed

Adding 6 employees brings your total to 30...
30*4.876 = 146.3 projects would have been completed, which is 110% of your 133 actual projects

All other factors being equal like productivity, etc.

This. 133 projects with an 88% completion means you completed 117 projects. Divide this by 24 employees working on it and you get an average of 4.9 projects completed by each employee. Divide 133 projects by 4.9 and you would need 27-28 employees to complete all 133 projects.

Your math is too straight line. 133 is a bit arbitrary, because it will change. Look at a 3, 6 or however many year average and factor in increases given your job. Then look at hours spent by those 24 folks. Did they work overtime, put in less than ideal amounts for each, etc? Get to an average hours needed rate per project, multiplied by your projected projects, divided by 1 employee paid hours and get the number of folks you need.

It will stay the same or decrease, the 24 employees will say, D@mn we finally got some help and will each slack off a little. The other 6 will barely cover for the loss.

Assuming the workload has a direct proportion of finishing tasks, it should go from 88% to 91%.

Look at it from the perspective of the unfinished work. If the group is 88% successful, that means they are 12% unsuccessful.

Adding six more workers is a 25% increase over the 24 original. Your unfinished tasks should improve by 25%. She 25% more workers should clear 25% of the unfinished work.

12 x 25% = 3

88% + 3% = 91%

Instead of 117 finished tasks, you would finish 121.

I am assuming that you might talking about clearing cases. The unfinished tasks are the issue because putting together a criminal case it’s not like picking up a certain number of items and you know where they are located. In those cases you are looking for an unknown. The unknown is the problem in clearing a task, not merely how many tasks a person can complete.

If 24 investigators can complete 117 out of 133 tasks/cases, that comes out to about five cases per investigator. If it was that simplistic, six more investigators 10 five cases would be 30 more cases saw. That means your unit could clear up to 147 cases a year. The problem is not how many cases can be cleared by each investigator but how much time till they have to find the unknown that they are digging for. So I think the key is a 12% unsolved rather than the cases per investigator.

Now if you are not talking about murder investigations…… I have no clue as to the answer.

Now if you were building boats and each person could complete five boats a year, it should be obvious that six more people could complete 30 more boats. That is not realistic in criminal investigations When you were building something, you know where the pieces are located. You just simply walk over and get them and put them together. That is where you could increase to 110% or 147 new boats as some of the other mathematical equations indicate.

Sorry, but most of you guys are using "linear" type of math; simple division, algebra, etc.

Statistics is a whole nother world. It's not a simple divide output by workers.

Wished I could help but I'm not a Statistician.

Do you divide the 24 into teams?
Do they interact between teams?
Is it 1 person 1 case?
Occasional crossover?

Rhetorical questions. I'm not qualified to do anything with that info. It's just food for thought.

Our guy just walked into the meeting and asked for 4 people and they said....done.

Not sure where youre going to get them from since everyone else is short but you can have 4.

But while we're at it. From 10/1-10/27

One group has 5 employees.............12 tasks

Another has 7.................................13 tasks

and the last 8.................................7 tasks

Group 2 is reported to be the busiest and needs people so getting one guy from group 3. Now I failed the same college math class 3 times and quit the whole thing but that dont add up for me
