What is the difference between the project management life cycle and the project life cycle?

Thanks for your invitation. Before using the life cycle phrase let us Explain the role of Porject Management as planning, control, montior and Manage all projects Elements to implement the project as per the agreed specifications and closing.

Reponsiblity of the project management will be not ending till guarantee period completion and project handing over to the customer. Then you can say the Project Management life cyclel is completed. 

Concerning the Project life cycle, it starts when the  Project Management takes over the Project responsibilty till the reliability test completion and  Real operation starts to produce the products and service as specified in the scheme of the project design.

Project Life Cycle

The project life cycle (which we prefer to call project life span) is a span of time from the project start to the end.In the SUKAD CAM2P™ model, the project life span covers the whole project from the idea statement to project closure.For most projects, this life span is divided into phases / stages. Each phase has a purpose, like a design phase, a feasibility phase, implementation phase, testing phase, etc.These phases could have different names based on the organization and industry.

Project Management Life Cycle

Project management life cycle is a term that is not used often and it can be confusing.Some practitioners use the term to mean the same thing as project life cycle; what we explained above.Others use it to refer to the project management processes that repeat in every phase … if you are familiar with the PMBOK Guide from PMI, the project management life cycle could be the same thing as the PMBOK® Guide process groups (initiating, Planning, Executing, Monitoring & Controlling, and closing). These processes repeat in every phase of the project life cycle.These process groups are derived from the quality cycle of Plan-Do-Check-Act.

The general difference is that project management is used to define, plan, control, monitor and close the project. The work associated with actually building the project deliverables is accomplished through work that is referred to as the “life cycle”. Project management is used to build the schedule, but the vast majority of the work in the schedule is the life cycle work associated with building the project deliverables.

Thanks for invitation....I endorse answers given by colleagues &Experts

Project Management Life Cycle is a " project management process which is same for every project " whereas Project Life Cycle ends when the project ends.
