I believe that in a project's life cycle, all subsections are essential when it comes to a product's development. When it comes to medical device development, the cycle is broken down into numerous of phases such as concept design (user needs), design planning (design input) , product design (design process), design verification (design output), design validation (finished device), design transfer and everything is connected with design review. These phases and controls hold an important role in the project's life cycle, this is the general project process cycle that the FDA uses as a guideline for medical device companies. As an engineer, the wheel doesn't need to be reinvented but instead to build upon the current technology and fix problems that user encounter currently while introducing innovative solutions. There aren't a least important phase because even the initial phase being the concept design, the user needs is what fuels the project and initiates the idea on what the user (costumer) is asking for, without this, the product will have no substance. The design review I believe could be a crucial part of the cycle since this helps the team to inspect all aspects of the phases and even beyond the completion of the product.

I think that the most important phase in the project life cycle is the planning phase. The planning phase is what lays out everything about the project and how to get it done. If this is done correctly then everything else will most likely go smoothly. If planning is done poorly, then its highly possible that something can go wrong in the following cycles. From experience, when you are uncertain of whats going on, and planning isn't involved; its like going into a project blind eye. I also don't think that there is a least important cycle; I think that all cycles are essential for the project life cycle because they all contribute in completing it.

Also, monitoring and controlling phase plays a very important phase, since we need to measure the results against baselines during this stage. I think Calculations in any project is a very important part to stay in the range of allowed budget.Its very important to monitor the team performance.So, I think the monitoring and controlling phase is the most important phase in the project life, since we need to monitor schedule, budget, resources, and the team performance.But we need to remember for any project you plan it then you do it.

I think the most important phase is the initiating phase. It is the most crucial to the success of the whole project; once you have a perfect initiating process everything else falls in place. The first thing when you decide to create a medical device is to look at the needs of the community and the customers that are going to buy the product. Then you look at the similar projects in the past to make the process easier, and look more into the budget and is the project going to make any profit or not. Once you have the team members and you did your research, you can move on to the planning stage. If you did the perfect planning everything else will be smooth and will meet your timeline. In my opinion the easiest step will be the closing phase, because you just finalize the project and again if the initiating phase is perfect, the closing phase will be short and easy.

I think in project life cycle there cannot be any single phase that can be more important than other because the end project would be a result of proper research and approach (i.e is initiation phase) well developed plan, thoughtful execution of the plan and timely monitoring and bringing changes when and the very end proper analysis of the whole project, what went wrong, where it went wrong, and make sure everyone is taken care of there needs (i.e. closing phase) mark the end of a successful project cycle.

If I had to select the most important phase I would say it would be the current phase or the ongoing phase.Let take random example of planning phase while planning if you miscalculate the budget or set deadline to tight to achieve or improper communication planing etc all this would be reflected in your execution phase and would also affect monitoring and control phase.
Now we take other example of initialization phase if the manager forget to take into consideration few features or few specs which might add to the value of the device or if some information where left to assumptions all this might later come up during the project and would affect the overall cycle. So no matter what if appropriate focus, attention and care is not given on the current cycle it is gonna affect all other task and ultimately on the project cycle. So I think 'CURRENT PHASE' is the most important phase .

All phases of the project life cycle are very important in order for a successful project. However, planning phase is extremely crucial for the project. This stage basically the core of the project where every aspect of the project is properly laid out. It is almost like a blueprint for the project. Many aspects of the planning phase are very important but for an instance, developing a communication plan is critical. In my earlier post, I mentioned how the lack of the communication plan resulted in a huge mishap which could have lost the company its client. Therefore, the planning phase lays a good foundation so that other phases proceed smoothly.

Planning phase and executing phase are by far the most important phases in product lifecycle management.

During the planning phase it is imperative to get all stakeholders involved in developing a timeline, budget, resource allocation, and solidified sequence of steps to make the project successful. Ideally one would want the planning phase to be set in stone. The reason why the planning phase is so crucial is because many times during a project one hits a roadblock that usually effects a timeline or budget. In industry, timelines, budgets, and compliance are the three most important deliverables of a project. This hindrance can be attributed essentially to bad planning or failure to understand what really needs to be done. Also, if a plan to implement a project is truly good, there is leeway to go back and change some steps along the way. This usually isn't the case, and instead you have to try to power through whatever obstacle is preventing the project from being implemented. With that being said, I have never worked on a project where the planning wasn't restructured at some point due to some issue.

Second, I would argue the executing phase is just as important. If at some point during the lifecycle that a project hits a roadblock or delay it is usually in the execution phase. This phase is crucial because poor execution leads to wasted resources and time. This is because some projects that are poorly executed lead to deviations and non-conformances and that in turn usually leads to revising a protocol or plan. I have found that during the executing phase, this is the best opportunity to learn because you realize what works and what doesn't. This ends up being a good take away because for future projects you will have experience in understanding and anticipating what does and doesn't work.

I would argue that the closing phase is the least important phase because the project is nearing the tail end and the closing phase usually requires wrapping up loose ends such as getting signature approvals and closing out some outstanding documents.

Every phase of the project life cycle is vital to the success of the project. However, certain parts of the life cycle can be a lot more crucial to the success of the project. In my opinion the executing phase is the most important aspect of the cycle. To be able to bring the medical device to the market it is imperative to test it in all variations and conditions. No stone should be left unturned during the execution phase. This could very well result in the product failing at later stages. To me the phase that can be the least important or crucial to the success of the medical device is the closing phase. All the hard work and regulation has been passed through the earlier stages. The closing phase is just there to tie everything together, there is not much pressure on this stage.

I do believe that there are two important phases in the project cycle. The controlling process and the planning process are absolutely crucial in running the project to completion. Although all of the phases are very important, I do believe that these are the most important. The controlling process is used throughout the entirety of the project and can easily be overlooked. However, it checks for the quality and completion of the project in its phases from start to finish. Without it, the product would not be exactly complete or favorable. The planning process is also important because it is an outline that should be followed throughout the project.

I do believe that it would be hard to choose which phase is the least important. Since the closing phase has the least time required, maybe that would be the least important phase. Though it is required to finish the project, the most crucial parts of the project have been completed. The closing can be done at any time, even if the other phases are complete.

In agreeance most of what rachelpatel1796 said above, I believe that the project execution phase (especially the controlling aspect) is the most important stage of the project cycle. The need for strict compliance to key performance indicators as well as carefully monitoring/ managing the various costs and time spent is paramount in seeing out the project though the longest part of its life cycle. This is primarily due to the tendency for scope creep to begin to take effect and this could have devastating consequences. These changes, although they may seem subtle at first, will snowball into project altering proportions and unnecessarily siphon funds away from the profits. In extreme cases, vision of the original project could potentially be completely lost and the project becomes one big money pit with no direction; embarrassing the parent company and employees alike. In addition, although no one part of the lifecycle is unimportant, if a decision had to be made, I would say that the closing of a project is least intensive if the rest of the project was executed correctly. When the rest of the project is run the way it was initially intended (rarely happens in industry) closing is filled with the documentation of the projects and aevaluations of what was most effective and ineffective for present, and future learning.

I have included a really helpful link below that further dive into each of the stages of the management cycle and all the components that comprise them. http://www.method123.com/project-lifecycle.php

I think the monitoring and control. In my experience, seldom I have been a part of a project and all phases ran it course smoothly without monitoring it and making sure that when the planning is being don’t that the deliverable that were determined in the initiation phase is meet. Or that the execution phase also insure the plan is carried our meeting the requirement in the initiation phase. I think that the monitoring phase is extremely critical to the success of the project. I don’t think there is a lease important phase because they all build on each other. Therefore is on phase is not treated with great importance the next phase will suffer.

I believe the planning phase is the most crucial to the success of the project. If a plan is well thought out then the actions, executions, and other phases after the planning phase will go to plan. That however, depends on the team and their willing to complete their tasks along with other factors. Planning a project is key because that determines what actions will be taken, when the actions need to be completed, who will be in charge of completing such tasks, etc. Without the plan, the project has no one where to begin. Nothing can be completed or executed correctly without a plan. With that being said, the least important phase of the project life cycle does not exist. I believe that every phase has their own importance but each phase ranges in terms of which one is more crucial than the other. Every phase plays a key role in the life cycle process and should be considered important.

I think initiation and planing phase is most important because in this phase you define your baseline. During these phases we gather the requirements and specifications for the project. Scope is defined in these phases which gives better picture of the project. Project objective are also constructed in this phase which helps in accuracy of project timelines and deliverables.

I don't think there are any least important phase since all the phases make a system. They all somehow depend on one another to function.

In my opinion, the initiating phase is the most important. In this phase, we have to decide what to do and whether it is worth to do. During evaluate the project, we will exactly know what we really want and whether should we go ahead. The achievable, understandable, affordable are the reason for the project. If not, terminate the project immediately is the only choice. At the same time, I think no phases are unimportant. All the phases have to be well planned and follow their steps so that the whole project will be done well.
