FS (Baseline) >> FF (updating)

Shaju,



Retained logic / progress override options has been discussed recently in the following post: plz check this.



http://www.planningplanet.com/forum/forum_post.asp?fid=&Cat=7&Top=33781



This will definitely help you out.



Anyway, it all started from to change all FS to FF with consideration to each activity’s baseline durations?



Cheers,

Dear Sridhar,



Let us go back to the core of the issue under discussion. I believe in retained logic option for scheduling, where the relationship is FS-0, the successor will not finish prior to predecessor finish.



Someone please correct me if I am wrong.

Dear Raviraj Bhedase,



i enterly agree with the comments you had made, what i mean to say is the same to Anoon Iimo, but there is a small interpetion, i am not saying that resources numbers to be used to be limited ( i mean ristricted), but instead of that u have think the no.of resouces to be used to complete the activity in that particular duration depending on the productivy and the workable space avaliable, if they are ristricting, may be you to brake the activity or chose the alternativy method of implementing your plan, for which we have discuss with the consturction team(dept.,)and other project team members.



hello Anoon Iimos,



sorry no it is not my point of concern, if i realied you arrongantly pls forgive me, i just gave my view what i though, i don’t mean that u r some thing what u have mentioned, if i had ever such kind of words unknowing or knowingly pls for give



hai to all,



i just discussing what i know ,just like throughing a ball and keep the ball rollwing so that by this kind of dissuctions i am empower my knowledge, i am not if i wright or wrrong , so i request you all to correct me if i am wrrong and advice me what is wright



thank’s

Dear Ponnaganti,



Yes i also believe that sometimes there are contractual restrictions on the durations of major activities (meaning group of activities), but for specific activities (i mean task), then i would rather suggest that you reckon it in terms of productivity rates.



did i sound like stupid and arrogant? (sorry, but i’m really is!)

hi sridhar,



Many specifications require activities to be defined with durations less than a set number.



The intent of this requirement is to allow for better monitoring and control of the work described by the activity.



Typically, the reviewer is allowed to wave this requirement in the case of Hammocks or deliveries, etc.



Working from consultant side, we are quite aware of LONG TASK DURATIONS (Case "Hours": Odd = 40, Case "Days": Odd 20, Case "Weeks": Odd = 10, Case "Months": odd = 4.)



But, please don’t apply this test to resources or summaries.



Cheers,



Raviraj

Dear Anoon Iimos



what i mean to say is that if in the contract clause there is Restriction on the duration then u do??



so what i mean to say is then u have break down the activity furter.



ofcourse what u said about Produactivity is the main factor( the number of resourses) the get the duration of the activity



this is my view



if iam wrrong pls excuse me and please through your views on me



thankyou

Sridhar

you can never put a limit on the durations of activities, it will be dependent on the resource productivity rates. Unless you’re just putting Durations by Guess! (which is mostly done i guess!)

i completly agree with Bijaya Bajracharya.



i would like say one that there should be a limit on the duration of the activites ( min. & Max.) otherwise while updating activites (mostly construction activites) it would give a wag concept on the situation on the project



if iam wrrong pls suggest me



thankyou

My suggestion is to replace FS relationship in such situation by SS and FF relationships. And this is real representation of situation as well. B cannot start until A has started. And B cannot finish until A has finished.

i suggest that you break your activities into bits and pieces if you’re using FS relationships to be realistic. Pre-commissioning of a certain activity shall never start until its predecessor activity is completed. You might create a very long schedule but that’s it. You got no choice if you wanted to be realistic.
