Primavera is the Enterprise Project Portfolio Management (EPPM) Software. It can be use for any type of project like Construction Project, other Business Projects etc. It is generally used for Project Management, Project Scheduling, Risk Analysis, Resource Management, Cost Analysis, Opportunity Management. The basic function of this software is to run the project smoothly without any delay due to extreme situation. It use Critical Path Method (CPM) in which the Total Float (Slack) is zero. You can read blog & watch Video about CPM vs PERT by click HERE.
Primavera was launched in 1983 by Primavera System Inc, and then after gain too much popularity in Project Management field in different organizations that it generate other Versions like Primavera P3 and SureTrak. In 2008 Primavera was acquired by Oracle Corporation. In 2010 Oracle ceased the sale of P3 and suretrak and only after that Primavera P6 is used for almost all types of Project.
Let’s Quick Overview of Primavera Interface and General features discussed in the video attached here:
This is one of the essential Documents while working in any construction Project. DPR actually shows the how your project are going on. It tells the progress of your construction work and other details like activities involve on each day, machinery involved or not, how many manpowers are there etc. You can add site pictures to visualize it in a better way or may be as simple document. You can prepare this document in MS Excel, MS Word, MS Power Point or using any other related tools. So here I have attached Sample format of DPR, also watch the video.
Program Evaluation & Review Technique (PERT) is a method used in Project Management to identify all the activities involved in any project and to find the unpredictable activities that upon the project is dependent and probabilistically define the time scale by the project to finish without any delayed not concern about the project cost.
Critical Path Method (CPM) is also a Project Management technique to identify all the activities involved while preparing a schedule, in any project and based upon this method critical activities can be identify upon which whole project is dependent. The time scale and cost both has to be considered, so that project can finish with expected date and with the allocated budget.
PERT is used for Non-Repetitive Projects e.g Research Projects
CPM is used for Repetitive Projects e.g Construction Projects, Organizational project management etc
PERT is probabilistic (time and cost cannot prospect in advance)
CPM is deterministic (time and cost can be prospect in advance)
PERT manages unpredictable activities
CPM manages predictable activities
PERT is event oriented
CPM is activity oriented
PERT uses three type of time to end of project that is Optimistic time, most likely time & pessimistic time
CPM considered and focus only on time and cost
PERT Vs CPM
This is the most basics differences between PERT & CPM. Watch the Video below you will make understand about how to find the Critical Path in any Project and about Early Start (ES), Early Finish (EF), Late Start(LS) & Late Finish (LF) terminologies with Example.
