There are Four Seasons hotels. There is Vivaldi’s “Four Seasons”.  And the four seasons of a project. A project is born, it works and beneficiaries harvest. Pretty much alluding to Spring, Summer and Autumn. Sometimes Winters enter projects’ lives. It happens in “frozen” project. Although some may challenge that a frozen project is still a project. Or, if all gone according to plan, Winter is the season of evaluations and reflections. Or just plain hibernation to recharge batteries.
This is a metaphor for project cycle management. It is just a perspective to the by-the-book definition.

Project cycle management (also known as PCM) is the process of planning, organizing, coordinating, and controlling of a project effectively and efficiently throughout its phases, from planning through execution then completion and review to achieve pre-defined objectives or satisfying the project stakeholder by producing the right deliverable at the right time, cost and quality, according to a classic definition.

Different methodologies speak of different phases/cycles and related tools. For example, in EuropeAid terminology the term project cycle management is used to describe decision-making procedures used during the life-cycle of a project (including key tasks, roles and responsibilities, key documents and decision options).

Some use the term “The Project Development Cycle”: the project begins, continues, ends and begins again. Some organisations manage their projects by the following 4 phases: initiation, planning, implementation, closure.

The PMBOK terminology refers to at least 3 phases in a project: initiation, intermediate, final.

The Project Cycle in the framework used by the World Bank includes the identification, preparation,appraisal, negotiation and approval, implementation and  evaluation phases.
At OECD, projects follow the identification, appraisal and detailed plan, implementation and monitoring and evaluation stages.

These are just couple of examples of different general frameworks applicable in different organisations. By all means, projects need to follow the sponsor/organisation’s rigours. Yet, finding your own perspective to look at the project’s life cycle in a simplified way, be it a seasons-view or any other view, is intended to make things easy for you and allow you to enjoy the process.  An accurately identified project’s season helps determine the right approaches and tools to design, plant, harvest or evaluate/mitigate.
