Life Cycle Assessment

5 minutes 5 Questions

Life Cycle Assessment (LCA) is a method used to evaluate the environmental impacts associated with all the stages of a project's life cycle from cradle to grave (i.e. from raw material extraction through materials processing, manufacture, distribution, use, repair, maintenance, and disposal or recy…

Question 1

Sophie, a project manager, is working on a project that involves developing an application. Her team is developing quickly to have a usable version ready, then improving and expanding it over time. She plans to use a combination of predictive and iterative life cycles. What type of Project Life Cycle is she using?

Correct Answer: Hybrid life cycle

The best answer is 'Hybrid life cycle'. Sophie is using a mixture of predictive and iterative life cycles, which is known as a hybrid life cycle. Predictive life cycles plan the entire project in advance, while iterative life cycles repeat the project's stages as necessary. By combining the two, Sophie and her team can plan ahead, develop a usable version quickly, and then make improvements over time. 'Predictive life cycle', 'Incremental life cycle', and 'Iterative life cycle' are not the best answers because they each describe only one method of project management, and Sophie is using a combination of two methods.

Question 2

Jane, a project lead, is working on a project where the result is not well-defined, but she understands the problem and is confident in her team's ability to find a solution. She plans to approach it with flexibility, making decisions step by step as they learn more about the project. What type of Project Life Cycle is she using?

Correct Answer: Adaptive Life Cycle

Jane is using an Adaptive Life Cycle approach for her project. This approach is ideal when the result is not well-defined, but the team has a good understanding of the problem at hand and can adapt to necessary changes as they learn more about the project. It allows for flexibility and iterative decision-making based on newly emerging project details, which is exactly what Jane is intending to do. On the other hand, a Predictive Life Cycle would not be appropriate here as it requires a clear-cut understanding of the end goal from the outset. An Iterative Life Cycle would involve repetition of project activities, and an Incremental Life Cycle focuses on delivering a functioning product through progressively adding project portions, neither of which is specifically mentioned or implied in the given scenario.

Question 3

Alex, a project manager, is charged with an externally funded project where a detailed, comprehensive plan is required before the funding is released. He proceeds to plan every single detail and stage of the project before starting. What type of Project Life Cycle is he using?

Correct Answer: Predictive life cycle

The 'Predictive life cycle' is the correct answer as it involves thorough planning of every detail and stage before a project starts. This is exactly what Alex, the project manager, is doing. In contrast, 'Adaptive life cycle' is characterized by a flexible approach with fluctuating priorities, which is not applicable to Alex's methods. The 'Incremental life cycle' involves the delivery of project outputs incrementally over time, and the 'Iterative life cycle' involves iterating through development stages with progressive refining at each step. Neither of these latter two reflect the detailed comprehensive planning described in the scenario.
