Otherwise known as the 80/20 rule, the Pareto rule is a tool that can be used to improve project management efficiency. The rule states that 80% of the results of a project come from 20% of the work. Therefore, by focusing on the 20% of work that is most important, we can improve the efficiency of a project.
It will depends on the "style" or culture of the organization. The rule of thumb is 15%-20% of the total project duration. More than that then there is a problem to be solve in the project management discipline implementation. Adding to add, some process like Scrum do not consider project manager as a role.
In simple terms, it's the concept that 90% of the work needed to finish your project will take a mere 10% of the time. But that final 10% push to reach the end? It will eat up 90% of your timeline! Think of it as an iceberg.
Productive project managers spend a BIG percentage of their time communicating, coordinating, and conflict mediating.
Contract managers typically work with business, finance and legal teams to discuss and conclude contract terms. In contrast, project managers work with different groups to manage a project for an organisation.
Project managers may participate in the contracting process to ensure they understand the project requirements, but it's typically only one part of their job. These professionals are primarily responsible for managing a project to ensure it stays within the expected scope, timeline and budget.
A Project Manager can easily perform the duties of the Contract Manager if he or she possesses the skills, hence acquiring negotiation skills, legal knowledge and being conversant with contract monitoring.
About 90% of the time in a project is spent on communication by the project manager. If this continues in a project, there is a danger of missing the deliverables or other outcomes as required by the sponsor.
Project managers are more in demand than ever, with growth projected into at least the next 10 years.
