Important Things To Know About Primavera P6 Calendars

Calendar for Activities

In the new calendar for Primavera P6, calendars are associated with activities. This allows you to add more flexibility to your scheduling and use multiple calendars for one project. For example, if two works are going on simultaneously at different places, one’s schedule will not affect the other’s work. You can use several calendars on more complex projects involving a lot of occupations to avoid confusion or clutter. However, you can still use one calendar for the entire project if this is what seems to be a more feasible option.

Activity Calendars and Resource Calendars

There are two ways in which you can create calendars in Primavera P6, activity and resource based. The most prevalently used calendars are activity based. For example, you need to perform maintenance of a machine every second Wednesday. In order to put that activity on map, a resource calendar can be created for that machine with the maintenance cycle scheduled into it. All other work related to that machine can now be scheduled around it, wherever the dependencies exist. In order for other related activities to become dependencies, you need to create “Resource Dependent” activity type.

Time Levels

There are three ways in which you can set time levels including; hours of the day, days of the week, and days of month / year. When setting up the rules, work can be scheduled at any of these three time levels. Here are few examples to help you know how you can set time levels.

  • Select days of the month or year that are workable or non-workable, it may include local holidays.
  • Select days of the week which are workable, like setting two days off as discussed above.
  • You can also select office timings, the beginning and ending hours for work.

Calendars and P6 Scheduler

There are different time zones and working days in various parts of the world. For example, in UAE the typically working week starts on Sunday and ends on Thursday, with Friday and Saturday off. These types of exceptional situations may arise when a project has unusual time zones to deal with. Create a calendar with Friday and Saturday off, Primavera P6 will never allow scheduling of any activity on these two days. All the work and non-work rules can be set in a calendar.

Changing Activities

Changing of activities in Primavera P6 can be tricky. Mostly, a new calendar needs to be assigned to an activity. Be careful when you assign a new calendar because the newly allocated time might add up to increase total duration required to complete the work. The adding up of time usually happens when the time levels are set in hours per day.

Primavera P6 calendars are a lot more comprehensive, although you need to learn them in order to work for you and not against you.

Common Project Control Mistakes Committed By Companies

Among many other reasons which unnecessarily increase costs and decrease efficiency of any project, one important reason is how management uses the tools, supervision, and planning to maximize productivity. However, this is an ideal situation where everything is in its proper place and there are no constraints that the management has to face. Projects control play a critical role in deciding level of productivity actually achieved.

common project control mistakes

A simple way to avoid this pitfall is to set projects control group and not the projects monitoring group which would help a company closely monitor data trends, oversee performance KPIs, and analyze work accomplished after each shift. Here are some of the most common project controls mistakes companies commit.

  1. They do not rely on any turnaround management process or formal project which would help them determine before time that milestones set at particular dates will be achieved. A project gated process or milestone schedule has to be in place to remain on course.
  2. They fail to establish effective project controls which would dynamically schedule planned activities on regular intervals like daily or on shifty-by-shift basis.
  3. There is no proper field supervision for execution of projects. These companies should consider independent field execution supervision. No matter how much resources go into planning, scheduling and coordination if all that has been chalked out cannot be acted upon. Every function needs to be designated to its relevant resource. A team made of individuals who are specialized in their own fields would produce a much better result in comparison to another team where the specialized jobs do not have designated individuals assigned.
  4. Companies may also lack in establishing formal processes which would help them proactively identify work that needs procurement or contracting.
  5. Some organizations overstretch themselves by aiming too high or setting unrealistic targets for quality of work, performance, cost allocations, and schedule durations. They should keep their primary focus on costs, quality of work accomplished, and safety of workers, everything else will eventually fall in its due place.
  6. The preliminary budget set by the companies is not correct and it fails to accurately determine scope of work. Some of the indicators which would be used in correctly estimating preliminary budgets include direct wrench hours and indirect resource estimates. One way of eliminating this problem is to use different tools to reach the cost estimations.
  7. Cost and benefit analysis tools can be very handy in determine the overall risks associated with a project. Asset management teams should rely on comprehensive tools like Primavera P6 to exactly determine scope of the project.
  8. Hierarchy of management plays a critical part in successful completion of a project. The hierarchy various from one industry to another but the key idea is to bring structure to the team. This hierarchy will help in all phases of the project including planning, budgeting, resource allocation, execution, cost controls, and quality assurance.

Management should avoid these common project control mistakes to ensure all projects are completed on time, within available budgets and without putting the workforce in harm’s way.

An Introduction to Level of Effort Activity in Primera P6

Level of Effort Activity means a special type of activity which has its own unique characteristics in terms of duration. Primavera P6 uses predecessors and successors to calculate duration of the level of activity.

What Constitutes Level of Effort Activities?

Level of Effort activities is mainly created to support the main project. The work done using this type of activity only help in completion of the project but it has nothing to do with the deliverables. However, it is important because it acts as a catalyst in completion of a project. The tasks performed under this type of activities are still critical to successful project completion. Some typical examples of Level of Effort activities may include clerical or admin work, project management tasks, meetings with clients, and equipment maintenance. Activities of these kinds do not directly impact the revenue which would be earned from the project which is why it is very difficult to assign values to them in numbers.

Level of Effort Meaning

The term has been coined to mean spreading of work. The level of activity is not crucial to work flow and should not appear on Critical Path.

Use of Level of Effort Activities in Primavera P6

The purpose of creating a Level of Effort Activities in Primavera P6 is to track time spent by allocated resources on supporting tasks. The predecessors and successors are used to get dates and durations of level of effort activities performed. In order to automatically calculate these durations and dates, you need to assign FF relationship to successor and SS relationship to predecessor.

The Calculation

The calculation is done by taking Level of Effort activities date from early start date and the finish date comes automatically from the successor. The Primavera P6 calendar is used to make the date and duration calculations. In order to finalize the calculation you will need to reschedule your project. The change in duration of any of the Level of Effort activities will automatically be readjusted.

How to show Level of Effort activities?

In order to show Level of Effort activities you need to make adjustments to Gantt Bar settings. Go to Gantt Bar, right click to select Bars. Make sure the entry named “Remaining Level of Effort” is checked. If there is no such entry made, make an entry using the add button. The “Level of Effort” activities form integral part of complete project schedules as they help display all supportive tasks. Get yourself familiar with them but make sure not to overdo it.

A Guide to Creating Effective Primavera P6 Schedule

Scheduling forms an integral part of project management. There can be hundreds or few thousand of activities which need to be scheduled. The scheduling without any predecessor or successor relationships can create multiple problems for the project manager. The interconnectedness decides the order in which all tasks can be executed to achieve desired results. Lack of relationships means no network which would have no critical paths to follow. Here is a look at some simple tips to avoid this dilemma.
Primavera P6 Schedule

Set Milestones
Milestones set you apart by standing out for anyone who is going through the layout. Make sure that all milestones are put under one Work Breakdown Structure element on top right of the project. All you need to do is to add one Work Breakdown structure which can be named Important Milestones. Now cut and paste every milestone set in the project under this WBS element to make things easier to manage.

Naming Cost Heads

The allocation of costs is a very important part not only for the accounting team but also for the management to understand flow of budget. Generic names for resources can only create confusion. The best way to name cost heads is to make them relatable. For example, cash paid or interest accrued is too general a name given to a cost head. On contrary, if you name it something on the lines of travel or daily wages paid, it will make things crystal clear for every stakeholder involved.

When to Be Vague?

Some of the projects started are very large and nothing can be said about their scope with certainty. This is the case where naming conventions should convey that sense of broader aspects of matters to accommodate the changes which would occur at later stages of the project. The use abbreviations should be intelligent yet balanced. If you choose too many abbreviations, it would make it different for the management to interpret various activities named. On the other hand, too few or generic names can also generalize or oversimplify matters.

Calendar Use

The use of calendars cannot be over emphasized. The best way to remain on schedule in Primavera P6 is to make use of as many calendars as possible. There are many benefits of using multiple calendars. The first major advantage is that different activities can have separated into sub-schedules or perhaps there may be different teams working on various parts of the project. Similarly, in some projects, each phase is not rigidly tied to another milestone or dependency in completion which means separate calendars of activities can be maintained.

Incrementing and Managing Activities

The default incrementing in Primavera P6 is done by 10. However, it is highly recommended that you increment activities by 1 instead. The creation of 1 increment helps you create a simple to understand numbering convention which would ensure no other activities are added at later stages to jumble things up. Unlike the older version, you will not have to renumber all activities should you feel the need to add one activity in between as Primavera P6 automatically increments the rest of the activities. And do not force yourself to set dates for every activity. Half of the activities should have constraints so you are able to understand flow of logic in dependencies without getting overburdened with too much data to understand.
