Project-VS-Project-Life-cycle

You may think that the project life cycle and the product life cycle are similar; they are not. As a project manager, you should know the difference between these two concepts to align your business objectives with yourproject objectives。

Since a project produces a product and then ends and the product stays for a longer time, the product life cycle is bigger than the project life cycle.

在PMP考试中，您可能会看到有关此主题的一些问题，因此请很好地了解。

Project Life Cycle

一种项目生命周期is the sequence of phases that a project goes through from initiation to closure. Projects are undertaken to produce a product, service, or result, and after delivering the output the project ceases to exist and the project life cycle ends.

一种项目生命周期has many phases, and each phase consists of activities from these process groups: initiation, planning, executing, monitoring and controlling, and closing. The phases are generally sequential and can overlap.

在开始阶段，您会开发project charter并确定利益相关者。

项目管理计划将在计划阶段制定，您将在执行阶段构建实际产品。

监测和控制activities happen throughout the project, although these processes can overlap or repeat.

In closing, you hand over the product to the client and close the project.

Project life cycles are not necessarily a part of the product life cycle. If the project’s output is a service or result, it will not be a part of the product life cycle.

这manbet最新版defines the project life cycles in four phases:

  1. Starting the project
  2. Organizing and preparing
  3. Carrying out the project work
  4. Closing the project

这following are some characteristics of a project life cycle:

  • Risksare higher when the project starts and decrease as the project progresses.
  • Staff requirements are low at the beginning of the project, maximum during the execution, and afterward, may decrease.
  • 这cost of changes is lowest at the beginning of the project, and it starts increasing as the project moves further.
  • 利益相关者influence is higher at the beginning of the project, and it starts decreasing as the project moves further.
  • Most of the funds and time are spent during the execution phase.

Example

假设您有一个建造新摩托车的项目。

First, youidentify the stakeholdersand collect the requirements. Once the requirements are collected, you will develop a plan to build the motorcycle.

这n you start the real work of building the motorcycle.

最后，您将把此产品交给客户，该项目将关闭。

产品生命周期

产品生命周期描述了产品从概念到退休的阶段。

这stages of the product life cycle are development, introduction, growth, maturity, and retirement. These phases are sequential and do not overlap. The project life cycle can be a part of one or more phases in the product life cycle.

In the development stage, you will generate the idea and create the product.

这introduction stage is for marketing the product and starting to sell the product to customers.

In the growth stage the sales increase.

In the maturity stage, the product is accepted, and sales are at their peak.

最后阶段是退休阶段。在此级别上，您将尝试销售所有库存，然后转到下一个产品。此阶段是由于技术进步而发生的，或者由于您的产品销售不足以支持其生产成本。

Please note that not all products reach the final stage; some are discarded and others never expire.

Product life cycle phases have no duration limit, one phase can be longer than the others. For example, the Toyota Corolla and Camry are old products and are still in the growth or maturity stage, and I do not see them coming under the retirement stage any time soon.

一种product life cycle can have many project life cycles. For example, the first project life cycle can be the development of the project, and the other, adding a function to the product.

在大多数情况下，项目生命周期是产品生命周期的子集，因为即使在项目完成后，产品生命周期仍在继续。

Example

Let’s consider the product life cycle for a new motorcycle that your company wants to launch.

这first step is idea generation. This includes a可行性研究, market research, and a business plan. Then you initiate a project to build this bike.

Once the motorcycle is ready, your project is complete and the project life cycle ends. However, the product life cycle continues. Now the next phase of the product life cycle begins, and that is selling and marketing the motorcycle.

You will provide after-sale support after selling, and finally, the retirement phase begins.

这retirement phase may include selling motorcycles at a discounted price.

During the product life cycle, if you add new functions to the product, you will create a new project for this process: for example, increasing the engine capacity of the motorcycle to support faster pickup.

这Differences Between the Project and Product Life Cycle

这following are a few differences between the project life cycle and the product life cycle:

  • 产品生命周期可以有一个或多个项目。
  • 这product life cycle is longer than the project life cycle.
  • 项目生命周期有明确的结尾，而产品生命周期可能没有。
  • 这map for the product life cycle is conceptual and depends on market conditions while projects have predictive and well-defined roadmaps.
  • 这product life cycle phases do not overlap while the project phases may overlap.
  • 阶段通常在产品生命周期中仅发生一次，而项目生命周期阶段可能会重复。
  • Phases are sequential in the product life cycle, while in the project life cycle phases may or may not be sequential.

Summary

这项目生命周期is a part of the product life cycle. The project life cycle is usually a subset of the product life cycle. The product life cycle starts from the inception of the idea and ends when the product is retired. The organization’s business model depends on the product cycle. A product life cycle includes the entire life of the product including updates and upgrades, however, products are upgraded with the help of a project.
