Good project managers will always make it a point to breakdown the tasks, deliverables and activities that are related to the project into chunks that are manageable and can be used at work.

This will also allow the team members to understand what is needed and what must be done in order to get the desired results.

However there are some disadvantages that come with work breakdown structure. Keep reading to find out what they are, how can you implement this at your workplace and what should you consider before making use of this approach.

Before we tell you about the advantages and disadvantages of work breakdown structure, here is a quick definition.

Work Breakdown Structure

What is Work Breakdown Structure (WBS)?

A work breakdown structure in every project management and system engineering is an effective tool that is used for defining and group the discrete elements of work in any project so that it can help the organization, build it in some way and boost the work scope of the whole project.

The WBS method of management has a proper team and manager with a good set of tasks which create the regular cost estimates and give you some important input to every project in all levels possible.

When we use the work breakdown structure method, the project manager and his team members will have a great idea on what is good and what isnt. It will depend on the requirements of the project that is needed to finish the job.

Major Benefits of Work Breakdown Structure:

The method of WBS is understood and used mostly by project managers since they happen to be the founder of planning projects. This may not be surprising considering the fact that there are a few benefits which could be gained from having a proper and well written breakdown of the work structure. If you are hoping to introduce this method soon at your workplace, this is what you should know.

1. Boosts productivity:

The structure of work breakdown will boost productivity at your work place. It facilitates the identification of skills which are needed to finish assignments on time. That in fact could boost the determination of people needed for the job.

Also it will boost the determination of the best number of people who are needed for work completion.

By having the right set of people and the right number of them on the job, the members of your team in general could help others become even more productive.

This may result in giving away the correct deliverables within time and set the needed costs which sometimes may exceed expectations.

2. Has detailed steps:

The structure of work breakdown will allow the team members to see the delineation of steps which are needed in giving the right products and service to all stakeholders.

The team members shall be able to understand all relationships between deliverables and steps. Plus all the discussions which are related to the delineation of steps can help a lot when it comes to handling ambiguities and clarifying them, narrowing the scope of projects and bringing out those assumptions which may often lead to increasing critical issues that may affect the performance of your team in an adverse manner.

3. Boosts transparency and accountability:

The structure of work breakdown will provide for a much level of details which will make it easy for those who are managing the projects. It will also let him understand his team members and hold them responsible for all tasks that have been completed.

This may also be applied for those members of the team who are in relation with the manager of the project and their own performance of work which is clearly a two way street that could encourage better and effective communication.

By having a proper and well defined breakdown structure, the team will enjoy a much greater level of transparency. Everyone will have a good idea on what everyone else should be doing and make sure to achieve all phases which will help in boosting a sense of harmony and unity among workers.

4. Best for allocating cost and time estimates:

The structure of work breakdown will also allow for allocating cost and time estimates for all those who have certain work packages. Such estimates may also boost a better and more realistic schedule as well as budget that the team members will follow and thus boost better team morale.

Just like the project tasks have been executed, the manager of projects as well as the clients and team members may then track the expenses and the cost which is in relation to such allocation.

There may be problems, issues and concerns which may be indentified quickly and addressed before they become the reason for regular procrastination in your projects.

5. Identifies risk in a better way:

One of the best work breakdown structure benefits is that it identifies all risks and threats that are ahead of you and reduces the chances of them. You have to keep this in mind that boosting risks in your project will not be completely eliminated but they could be minimised so that they post dangers to the accomplishment of the team.

The risk may also be used to track a project log, reviewed during projects and its execution. The best thing you can do here to check risks is to see all the branches in the breakdown structure and identify one which has less parameters.

6. Boosts progress in monitoring:

The breakdown of work structure may also be used very easily to identify and quickly see the deliverables that are affected due to any delays in the project or because of certain work packages or maybe sub deliverables.

The faster you will get the source of such delays, the better the impact will be. Not just that, you will be able to take good action much faster and save your project from getting ruined. Since all projects may be monitored, the members of the team will be more motivated and connected in doing their work.

Also having good participation in the evaluation of WBS will boost much deeper motivation and performance.

After knowing its advantages of work breakdown structure, we will move on to the disadvantages of work breakdown structure.

Disadvantages of Work Breakdown Structure:

Despite having so many benefits of a work breakdown structure, there are a few cons that comes with the work breakdown structure. Keep reading this section to find out what are the possibilities and how you can find a solution to them.

1. Having a step by step approach is a pain!

The thing with work breakdown structure is that it has to do list approach which could be quite a pain since it stems from the belief of your manger that the WBS is done step by step.

Having such an approach can lead to the idea that managers will walk around in the checklist and they may be used to check off all items as it has been completed. Ultimately this could lead to micro management which may not be attractive to some team members.

2. The problem of requirements:

When you keep a certain deliverable on the WBS, you could end up breaking down into the activities which are required for its creation. What really doesn’t work is that it will breakdown that deliverable into the requirements that help in describing it. Deliverables and some tasks, upto a certain extent belong to WBS but requirements certainly don’t.

3. No Buying in processes used:

The project team will be using all its experience and expertise that could be used to get down the specifics of such deliverables in a natural manner that the WBS could be drafted with some input from all the members of its team.

If the manager of the project creates the WBS with very little input from other members of the team project, the people may turn a very little offer to no support at all from the WBS. Yes, it will be a little time consuming but in the long run it will pay to engage the leaders.

4. Having plenty of tasks to do at one go:

Having team members, you get to become more productive and hold them accountable for reaching such achievements instead of just finishing a list of tasks.

When you use the method of work breakdown structure, you will be breaking down all tasks within a few hours so that you can compete. But the problem is that the workers end up spending a lot of time on the small tasks and the managers have to keep a track of all of them which is quite a mess and ends up giving very poor results.

Due to a general rule, the WBS tasks must have durations between a week and around eight weeks.

5. The orientation:

The structure of work breakdown could become the outcome of oriented but not prescriptive methods. Methodology may change without any changes of the planned outcomes. Deliverables or maybe planned outcomes must never be closely blended with the other methods and actions.

6. Having more than 100% of WBS:

A very important design principle of WBS is applying 100% percent rule which will state what it includes and its project scope at the same time. but there are times when we actually hear people say they have around a 110% of themselves during a certain project. Even though that is perfectly alright for individual, a project could be doomed to failure in case the WBS may be included more than 100% of the scope. It is also a good measure against scope creep and we have a good idea of the problems that such a creep can cause.

7. Cant get you correct details:

Anyone who has used such a method in life will definitely agree with this one point. It is definitely hard to find the best and most accurate level of details when it comes to WBS. Since you have to fit just one on the page, it will become extremely difficult to find what exactly the tasks are and what must be the creation of them added to the WBS. This may lead to creation of useless and vague tasks under which you will have a list of non similar tasks.

8. Becomes outdated quite fast:

Even the WBS method can dictate the project and schedule the whole thing, it does become outdated after a point. This is probably because the schedule of the project will change the execution of such projects but the WBS shall always be the same. When you update the WBS, you will not have any project manager who can help.

9. An overall summation:

The development of work breakdown structure is surely not easy. The process is quite painstaking. It could take you some time. Having a big work breakdown structure could take several hours for development. For others, it may need effort. There will also be a knowledge transfer and exercises of brainpower.

The larger there is a scope of your project, the bigger the WBS will be. More people must also provide the input and then check the portion they are expected to do.

Finally, it also expects you to have refinement. The initial iteration is hardly right and when the project changes, the WBS does too. Therefore if you are going to choose this as an approach at your workplace, choose it wisely.
