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.Read more
As a follow-up to the post about the difference between a time buffer and total float; here is a new post in the same series – seemingly easy concepts that seem to confuse many. This one might be an open door for financial or general management profiles, but it is not for most project controls engineers.Read more
Duration and Calendar Duration, Time and Units/Time explained, P6 basic.
Time is of the essence. Both in project control and in our personal lives. As we’ve been dealing with time since childhood, you would assume we have learned to communicate on it effectively and unambiguously. But when someone says: “this activity is going to take 48 hours” you might take that as 2 days while he might’ve meant it will take two persons 3 8-hour-working days to complete.Read more
Do you feel your budgeting process has failed from the start of your project? Have you learned that you overbudgeted or underbudgeted the activities in your performance measurement baseline (PMB)? Are you willing to take your Earned Value Analysis (EVA) to the next level? Then this is a blog post for you.Read more
When using the Critical Path Method (CPM) in traditional project management software, Total Float (TF) and Free Float (FF) are calculated, which most project managers know and use. But there is more to it. We can gain deeper insight in which timeframe an activity can shift, and the effects on the related activities by calling in two more types of float. The Interfering Float (INTF) and the Independent Float (INDF). Let me tell you how to interpret them, help decision making, and support claim prevention/preparation by using these four characteristics.Read more
Primavera P6 is designed as an Enterprise Project Portfolio Management (EPPM) tool. Even though often used as a standalone tool, Primavera P6 is a database initially designed for the enterprise’s needs where data can be shared between projects. In order to achieve this Primavera P6 uses the concept of “Global” data objects and “Project” (or embedded) data objects.
In this blog I will show you why using a project calendar over a global calendar for your project activities schedule is beneficial to maintain control over your project(s).Read more
You are halfway through your project and you want to know if you are still going to achieve your project objectives. By using an Earned Value Management System, you know how to estimate your total expected costs (Estimate at Completion), but what about your deadline? Based on your current information, can you say something about the expected finish date of your project? This blog gives you an overview of how to use Earned Schedule to predict your project finish date.
Each large construction project brings new challenges. One of the challenges from a project controls perspective is to manage changes. The objective of this blog is to create awareness of the different levels of change during project execution and gives a brief answer on the following question: Which type of changes are we dealing with?Read more
How can we get the most out of our EVM metrics? We’ve evaluated our current cost and schedule performance, and have seen how to forecast the Estimate At Completion (EAC). Now is the time to evaluate the realism of our project’s Budget At Completion (BAC). Following the current conditions, is the aimed for budget still sufficient?Read more
Balanced Scorecards are widely used among business and industry, governments and non-profit organizations. However, they are not so much discussed within Project Management and Project Controls, in particular. So, you might wonder why Primaned is writing about them?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
Now we’ve learned the basics of Earned Value Management calculations (see this blog), it’s time to introduce a new metric to define our project’s health. As you’ve noticed all previous metrics and parameters were either percental (CPI, SPI, TCPI) or monetary/unitary (CV, SV). But what does a schedule variance of € 10.000 tell us? First, a delay expressed in monetary units is somewhat strange. Second, we will show later in this blog post that this metric is subject to a major fallacy. It is to be replaced with a more comprehensive one. Time for change.Read more
As consultants, we frequently come across schedules of substandard quality. You’ve probably seen our top-picks of mistakes as well: overuse of SF-relationships, too many constraints or even the absence of links between the activities. We receive requests to perform a schedule quality analysis more often these days, so it seems that the market starts understanding the importance of quality standards.Read more
The era of the big shot project manager might be over.
Project management has evolved into such a multidimensional profession, that it is no longer realistic to expect a single person to show excellence in all facets of project management. Different aspects of project management require a different skill set.Read more
