Website Upgrade Incoming - we're working on a new look (and speed!) standby while we deliver the project

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.

Regardless of the terminology used all projects need a coding structure which, apart from other uses, provides a link between the cost estimate, project budget and project schedule. If done with common sense and not ’hi-jacked’ by SAP type accountancy requirements (which usually differ from the facility/equipment view of an engineer)it becomes a fairly simple matter to relate tasks in the schedule to their appropriate costs/quantities in the estimate/budget. I find recently that Clients using SAP systems often ’impose’ WBS structures that are based on cost accountancy formats and do not suit the way engineers view a project structure.

You can also add a useful Contract Breakdown Structure for Alliance or Partnering jobs if one Company is doing several parts of the job under different contracts. You need to choose software that allows you to have multipule hierarchical structures rather than just one WBS

cbs is cost breakdown structure, this is allows you to break down the costs (thats right) cost breakdown structures allow accountants and cost engineers to break down the project into elements that are easy for them to forecast and track.

obs is the organisational breakdown structure and is determined by responsibility.

meh... its all bs to me :D
