A time schedule might be set up with the utmost care. It can be of top quality and resulting from the collaboration of whole teams of experienced professionals. Several working methods might have been studied and historical production rates analysed and amended for the new project. Actual performance will be very close to the initial baseline, won’t it? Of course, you know where I am going with this, especially because you know the title of this blogpost ?.Read more
When I started working with Primavera P6, I had a colleague who showed me how you can use ‘global change’ to make sure that your baseline bars are showing the right information. It was fairly simple: you just amended the planned dates to the dates you want in the baseline, and it’s done. Hu? Primavera is not capable of managing baselines? Of course, something else is going on. Like so often, Primavera turns out to be so powerful and versatile that one really needs to understand what’s under the hood to properly operate the system.Read more
Every planner regularly encounters negative total float in schedules where he didn’t expect it. This happens more often than one would like. And every time this is the start of a nerve-wracking search for the cause. In this post we list the most probable causes to give you guidance on where to start looking.Read more
Calendars can have an impact on the total float activities, and thus on the critical path. This might seem somewhat confusing when first encountered, but once you understand how Primavera deals with this, it makes more sense.
An important consequence of this is the potential difference between the critical path and the longest path Primavera P6 can calculate. Standard settings in Primavera P6 will show all activities with zero total float as critical, but the longest path can consist out of activities with different amounts of total float. Find out how calendars are related to this and continue reading.Read more
There are numerous reasons why a schedule should meet certain quality criteria. Have a look at our blogpost “Schedule Quality – Technical Requirements” for the details. One of the more widely spread tests to assess the (technical) quality of a schedule is the DCMA 14-Point Schedule Assessment.Read more
Managing change will always be a challenge in projects. Its importance cannot be overestimated in order to successfully deliver projects. Messing up will have huge implications in a claim-oriented environment. Still we see many project teams struggling with organizing and following a proper change management process.Read more
The role of a project controls professional is in many ways affected by the tender or contract requirements related to scheduling. I’ll refer to the ‘schedule requirements’ from now on for simplicity. If you are at the project owner’s side, your expertise may be needed to draft up these requirements for the future contractors to comply with. If you are at the contractor’s side, you’ll be responsible to make sure that the bid complies with tender requirements. In a later phase, during execution of the contract, you’ll have to guard that all actions and submitted documentation comply with the requirements.
But what can be found in those requirements and what do you have to pay attention to? It does not matter if you’re part of the owner’s or contractor’s project team, it is indispensable to involve a professional with profound knowledge on the subject, because you quickly end up in highly technical discussions between the parties involved.Read more
There is more to showing THE Critical Path in Primavera than your project manager can imagine. Primavera allows you to change certain settings to define the criticality of activities: you can define a threshold value for total float, or choose for the longest path instead of a total float-based critical path.
It is likely that you are interested in all activities that drive a certain milestone. And it makes much more sense to monitor the longest path towards this milestone instead of the critical path defined by total float. This very useful option is however a little bit hidden in Primavera P6 and I desperately want to share it with you! It is a method I use on EVERY SINGLE PROJECT.Read more
When reading through the endless search results while preparing this post on the role of the Planning Engineer and Project Controls Engineer, I came across a company’s website which showed their desperate need for people filling in roles related to project controls in their organisation. They were recruiting for:Read more
Critical Path Method (CPM) schedules have been ruling the world of projects for a long time. Considering the benefits of CPM, that is quite understandable, isn’t it?
They provide the bigger picture of the project and allow for scenario and what-if-analyses, risk analyses, delay analyses and critical path analyses. They are useful for assessing the resource needs, they provide the team with due dates for ordering long lead items and they allow to include contingencies for risks.Read more
