Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

Planning process is linear or is iterative?

Dear planner:

Some planners stated that the construction planning process is not linear but iterative.


do you agree?? and why??

Ahmed,

the same may be done using project management software.

Why do you need Excel?

Dear planners;

 

I want to share our experience in monitoring progress for Railway/Line projects.

for my self I'm using excel (Multiple columns: Km ponits each 5m; zones; area; phases of work; date of achievement of each phase on each Km..) so I can have  Three results; Graphical of the progress; Progress by Zone (Area) with possibility to choice the cut off date (Can get the progress on older dates); and the cumulative progress by months or week.

I found this method very useful and easy, please if you have another methods please share.

Can I nominate the above for the "Favorite quotes about planning" thread? :-)

I basically agree with Gary. However, there are certain occasions when the plan is also not totally linear: when rework has to be performed after a failed test.

If the rework has been pre-planned in fragnet form (as it should have been), then in a sense the plan is still linear. but the "product" has to go through reiteration.

Them semantics things is a bitch, ain’t they?

Fraternally in PM,

I think we’re talking at cross purposes here.

Hi All

I can’t help but jump in here.

A fully developed bottom up plan with FS links and one critical path is Linear.

It can be nothing else.

Even when progress is added the linear nature is retained.

In PowerProject there is the option to "Link Around Completed Tasks"

Best regards

Any time you enter information, analyse it, make changes, then re-analyse, it’s an iterative process. Planning is definitely an iterative process

example (when developing a schedule):
"We’ve got 10km of pipe to put in the ground. How long will that take?"
"4 weeks"
".....that’s no good. That pushes us past contract completion"
"OK, I guess we’ll have to hire an additional welding crew. That would bring it down to 2 weeks"
"perfect"
...is an iterative process.


example (when updating a schedule):
"The pump is going to be delivered 2 weeks later than planned -shipment has been delayed by adverse weather"
"Oh dear. That was on the critical path. Is there anything we can do to recover the delay?"
"Well the diesel gen is due in 1 week. we could recover some of it by installing that first, if we can get the foundation done in time."
"OK, pull the boys off the pump foundation, and get them cracking on the diesel gen. Pull extra manpower from the admin building if you need to"

...is an iterative process

There is the answer to the question,

If you are using CPM (90%), then it is linear.

Most of my planning is "out of the box", with a degree of blue sky thinking. If we are not all on the same page then I run it up the flagpole and see who salutes. However we MUST reach out for an end to end solution. To touch base together, aim for evolution NOT revolution.
