Effort hours

[Former Member]

Hi Experts,

I have to give effort hours for the bidding proposal...Can anyone tell me how much does any inbound or outbound would take to develop.

I want to know just a rough idea as without much information can't really get onto the real time hours efforts.

As an example if the integration in between SAP to mainframe which can have one inbound and one outbound interface. Please let me know would I be using file adapters for this or is there any other adpter avialbe for the same?

Quick reply will be really appriciated and thanks in advace for help.

following is quick estimation I used:

1. Simple scenario: 16 Hrs

2. Medium: 22 Hrs

3. Complex: 35 Hrs (complex BPM etc)

Risk: @10%

PM: @10%

These hrs including:

- Observing quality processes/standards (CMMI)

- Testing (not included UAT)

- All configuration etc

- Beginner to Moderate experience level

Not included:

- Installation of XI and related components.

I can understand during bidding most of the detail information not available but in proposal you may get good idea about complexity level etc.

Try to achieve reusability which can reduce effort later on.

Gourav

Hi Sachin,

Man hours depends on the particular scenario you are going to work on. It varies for each and every scenario depending on the requirement. If you have all the requirements before starting the design, it will cut your work hours atleast by 50%. Most of the scenarios we developed, we had unclear requirements and they change too often. Take care of this. Next thig is to condider these points

1. Do you need custom developed adapter modules for this scenario?

2. Do you need JAVA/ABAP/XSLT mapping?

3. If Graphical mapping can be used, do you need some UDFs?

If you can get answers for all these, then your man hours can be calculated roughly.

P.S: For connecting to Mainframe systems, we generally use File adapters and for SAP you have 3 options

1. Proxy

2. RFC adapter

3. IDOC adapter

Hi Jay,

Thanks for your reply, I understand your concerns fully and I wish I could get all these answers but I can't get this information from the customer this is just an initial bidding so have to give them rough idea of effort hours.

Can you share how much time did it take in ur interfaces for main frames (each outbound and inbound). If it is simple file adapter and using graphical mapping or any other mapping.

And what do you mean by UDFs?

Sachin,

30 - 40 -30 ratio would help in this case where 30% of interfaces are classified as simple, 40 as Medium and 30 as Complex.

Decide how you will bill for a simple interface , and so on and do the needful. At times such rough estimates do the trick when nothing is avaialble.

Hi Sachin

I think ,it is purly depends but mostly estimation as follows

30 -40 -30 is the right ratio : simple -- medium -- complex

In general Simple scenario's will take about 2--4 days but here depends on

mapping(File related, no BPM's, Simple graphical mappings .....)

Medium scenario's will take about 4--5 days

(Idoc,BAPI,Rfc, mapping simple functions....)]

Complex scenario's will take about 8 -- 11 days depends on complexity

(Bpm's, Sync & Async calls, mapping udf ,....)

Note: The above may vary depends on the scenario and it includes time for

testing as well documentation.

It is general using the existing adapters but in the developing the own

modules , it may take some time

I hope this will answer your question

regards
