Method of estimating software workload (unfinished version)

What are the methods for estimating software workloads

================================================

> I'm not particularly familiar with the concept, and I'm going to check the data myself. I think there are about 3 kinds of estimation methods, which are based on WBS based on Sloc and FP-based workload estimation.

> First of all, this WBS-based workload estimation method, I personally think it should be by virtue of the previous experience to do similar projects to preliminary estimate, and then each decomposition also according to their own experience to estimate the time, the final calculated total time and the previous preliminary estimate to make a comparison, and finally arrive at approximate estimated time.

> First of all, the advantages of this estimation method, I personally think that there are some of the following

+ Estimated time-consuming is less, so the cost is also low;

+ High Accuracy in some highly similar projects;

+ Easy to operate;

> Shortcomings, I personally think there are some:

-risk will be relatively large, it is likely that some of the difference between the place is not aware of the estimated time difference is very large;

-Not very formal, is a kind of a little basis for guessing;

-Low accuracy for projects with less similarity;

> Like I've never had a project, so let me choose I'm definitely not going to choose this method, after all, no experience.

> Secondly, the method of workload estimation based on Sloc is mainly divided into productivity method and parametric model method, and the productivity method looks at some information on the Internet.
