Project estimation metrics?

I've been asked to come up with a formula for estimating C# projects. Does
anyone know of a good source for this? (website, book, etc.)

Although I know of no such resources, I can tell you that there is no single
formula for estimating time. From my experience, it takes experience to now
what a project entails.

I have seen attempts at estimation for project that rely on the number of
forms or the number of tables in the database. I have found these not to be
very accurate because there are many factors that must be taken into
account.

1) How experienced the devs are that are working on the project and are
there any new technologies that must be learned.
2) Will there be an architecture or just use the quick-and-dirty features
of VS.NET.
3) Will it be ASP.NET, console, webservice, etc.
4) The complexity of the database.
5) The complexity of the forms or pages.
6) (and many others that I cannot think of off the top of my head)

Maybe you can clarify your phrase "formal for estimating".

Hello Ray,

I recommend to read about COCOMO and PSP/TST
These methods based on "proxy bases estimates"
Small description:
- use UseCase to assess amount of work for each module in lines of code
(LOC) and general solution (proxy)
- for each module forecast the deadline bases on PERT Estimation (read
- get PERT productivity factor LOC/hr

It's just a glance on estimating project. Being a certificated PSP engineer
I recommend to read about PSP. I found it strongly usefull for those who
are concerned about his own productivity and quality of code. For me it gave
an outstanding result

This looks encouraging. Did you mean PSP/TSP?

The Personal Software Process (PSP) by Watt S. Humphrey is the current best

Hi, I am pulling over 400 different metrics from an Excel spreadsheet into Access (97). Conceptually, each row represents a single set of these 400 metrics. However, because of the 255 column limit in Access I am faced with a dilemma: Do I create two tables (1 with 255 columns, the other with 145) and a lookup table that stores which metric is found in which table? Obviously this method would require VBA logic to coordinate any time I

Does this sound familliar to anyone? Regardless of the fact that you have been programming in Access for umpteen years, you still are overly optimistic when it comes to estimating time. The client gives you a requirement that is "obviously just another form", and your brain does a quick calculation, saying that should take 1 to 2 hours. You know you tend to be optimistic, so you double the average of that, and call it 3 hours.

I'm an Enterprise Architect at a large insurance company. My background is Java, and I have brought in the CodePro metrics & code audit tool that runs automated metrics and code audits within Eclipse/WSAD. I'm interested in finding some similar tools for our C++ developers, who use Visual Studio as their IDE. Does anyone know of any C++ tools of this nature that integrate with Visual Studio?
