A brand new project allows you to report a time expectation. You may know about the time and report a person's budget.
Two months, three people (six people for short )...
This is probably the case, right?
So I ask you? Where does your time and manpower solution come from? What is the basis of the source?
This is a valuation, right? Is this valuation derived from your rough expectation for the project? The expectations you derived from your own experience, right? We will not mention how to add positive and negative errors here.
Then, the higher the understanding of the project, the more accurate the deduction expectation, right?
However, kiss:
- For new projects, you only understand the requirements, not the business. Do you think the complexity you evaluate must be real complexity?
- Is your experience reliable even when you evaluate the complexity and use experience to evaluate it? Or is it reliable in this project?
- At the time of derivation, you must have estimated the manpower, and then use the manpower planning. Even when you predict it, you have placed the manpower on a specific person, right?
- ...
These inferences are probably from experience, right?
But, kiss, I want to ask a question:
Is your experience really reliable? You may be brave enough to say it is reliable. 100% is okay !!! Your boss and subordinates may trust your words. But what if I am a stranger? How do you persuade me? You want to convince me not to miss me, especially those who are more real. to persuade me, you must come up with evidence. What evidence can you come up? Project A is normal? Project B is normal? ...... First, do you have such evidence? Is this evidence? These are just a result. They do not mean that the plan derived from experience is reasonable! I need a quantifiable way to tell me that you are correct!
Do you have one? Yes ???
Let's take a look at this question first. We will discuss it later.
As described above, we often use units such as "person. Month", "person. Hour", and "person. Workday", right? Number of persons in this project. Month Number of persons in this module. Workday How many people are using this function. This is generally the case, right?
It looks good. We have used a very scientific calculation method..
"I smiled ."Famous saying!
What is "man. Month" and "man. Workday ????
Haha, I laughed again:
It's all fucking nonsense! They're all fucking dummies !!! In terms of "People. Workday", "workday" is basically quantifiable: 8 hours a day.
What is the "person" standard ???
So I said I could only smile! Of course, this smile targets myself!
I was asked a similar question, and I was speechless. I even asked a lot of people to ask:
How to make a scientific assessment of the project!
Let's break it down next time!
