Dear All,

           I'll be grateful if someone can please advise on how to estimate effort for setting up a website using MK-II FPA. {N(input), N(output) etc}

Many thanks for your time,

Regards,

Hi Kimbo,

                 Many thanks for your response. I am very new to Business and System Analysis and in process to learning Function Point Analysis.

MK-II FPA is

"MkII FPA

The method

Based on a method devised by Charles Symons and described in his book “Estimating with MkII FPA”, the MkII FPA method has evolved through 3 versions, the most current of which is V1.3.1.

The main feature of the method is the simple measurement model; there are only 3 components to consider:

• Inputs: Data coming into the software from a user in the external environment
• Outputs: Date leaving the software to a user in the external environment
• Entity References: The Storage, retrieval and deletion of date from permanent storage.

I need to calculate Function Size & Effort using this method:

"Calculate the Functional Size
The Functional Size (Function Point Index) is the weighted sum over all Logical Transactions, of the Input Data Element Types (Ni), the Data Entity Types Referenced (Ne), and the Output Data Element Types (No).

So the Function Point Index (FPI) for an application is:
FPI = Wi * SNi + We * SNe + Wo * SNo,
where ‘S‘ means the sum over all Logical Transactions, and the industry average weights per Input Data Element Type, Data Entity Type Reference and Output Data Element Type are, respectively:
Wi = 0.58
We = 1.66
Wo = 0.26

I need help finding Ni, Ne, No for a website creation project..???

I hope this clarifies the situation,

Any help very much appreciated

Hi Kimbo,

               Many thanks for your response. I completely agree with you on calculating Function Points. I think experience comes first in BA field. You are also right in saying that I don't have any information on company's development history so I have to rely on industry weightings.

I'll be very grateful if you can please help me with this issue and also let me know from where to study more on method suggested by you.

Company(book shop)  is looking for their first website and want it to be functioning like (http://www.amazon.com/). How many function points you think are there for this website??

secondly how I should proceed further for estimating effort and cost.They also have requirements like Allow customer online wish list, allow customer online book review and allow order tracking etc. (similar to amazon.com)

I look forward to your response,

Many thanks once gain for your precious time,

Kind regards,
