The project life cycle is a series of phases that a project passes through from its start to its completion. It can be either plan-driven or change-driven.
1. Plan-driven projects have predictive development life cycles (sometimes referred to as waterfall) that require scope, schedule, and cost to be determined in detail early in the life of a project, before the work begins to produce the project deliverables.
2. Change-driven projects use iterative, incremental, or adaptive (agile) development life cycles, and have varying levels of early planning for scope, schedule, and cost.
2a. Incremental and Iterative life cycles involve early planning of high-level scope sufficient enough to allow for preliminary estimates of time and cost; scope is developed a little more with each iteration.
2b. Adaptive development life cycles involve a fixed schedule as well as fixed costs. Scope is broadly defined with the understanding that it will be refined throughout the life of the project. Work is planned in short increments to allow the customer to change and re-prioritize requirements within the time and cost constraints. Saving Changes...
A human life cycle is baby - toddler - child - adolescent - adult - senior citizen and there are activities and milestones within each of those stages.
Projects similarly go through stages with specific activities and milestones in each stage or phase.

The best way to understand it is going to IEEE Standards on the field. There are a big confusion outside there. I participated in PMI´s standards creation and review try to help on clarify but it still remains. You have life cycle models, basically two: predictive and adaptive. On those models life cycle process are created, a lot: sequential, waterfall, iterative, incremental, iterative-incremental, spiral. For example, life cycle process call "agile" that not exists. Unfortunatelly is an invention mainly pushed by the PMI to call in this way iterative-incremental life cycle. With basement in life cycle process methods/frameworks are created. You can mix all to create your own method/framework. Saving Changes...

Project life cycle in construction industry moves like pre project decisions --design --planning--construction--closure of the project
construction phase life cycle can be more elaborate way like --contractor selection --site mobilization-- routine operational --termination of the project

There is the Project Life cycle and then there is Project Delivery Life cycle.
The Project Delivery life cycle starts with project authorization, say the Project Charter, and ends with Project Delivery or what some refer to as Closure or termination.
The Project life cycle starts with an idea and ends with decommissioning of the facility or service that the project delivered. As Kiron said - from birth to death and all the steps in between.
In the infrastructure sector the only way to determine true value is to consider not only the project delivery but also its operational, maintenance and final decommissioning costs. As an example a change may result in savings of effort in the delivery but require much more in maintenance and operations.
Many of us are involved only in project delivery or operational side of projects and do not easily see the bigger picture.
More and more clients are insisting that the total picture be brought into focus, delivery and operations. Project life cycle is being redefined as beginning to end of the product not the delivery only.

I would call that the difference between the project lifecycle, and the program lifecycle. Projects tend to end at the delivery of a first unit. Operations, maintenance, upgrades, and final decommissioning, are often large enough to involve a number of additional projects over time. Once the first unit is delivered, there is a switch in color of money from development to revenue generation (different taxation for the finance dept). They're all under the same program, but the program authorizes distinct projects throughout the operational and retirement phases.

Keith, I would argue that you are describing the traditional approach to projects - ends with delivery of the product.
Organizations, including governments, are now focused on the longer picture. Many projects adopt the Design, Build, Finance, Operate and Maintain (DBFOM) model where a team or consortium is put together to over-see and manage the entire life cycle over a thirty-plus year time period.
The key here is to make sure design and build takes into consideration the future effort to operate and maintain the facility.over the long haul. The effectiveness of the deliverable is measured by its long-term performance. Saving Changes...
