Work Breakdown for maintaining aboveground swimming pool
The industry involved in the following work breakdown study is household recreation. The high level deliverables of the project include a single summer season of safe and healthy family fun in the water, including appropriate levels of water sanitation and safe levels of appropriate chemicals. Since the pool has already been constructed, this WBS concerns only pool maintenance. The resources required for this project are minimal and include $300 in common pool maintenance products available at home improvement and pool specialty retailers. This project requires labor equivalent to roughly three hours per week aggregated over a three-month period.
This generic WBS was used to maintain the pool, and it was effective in organizing maintenance efforts and ensuring timely testing. A scheduling system was devised through the use of a disposable weekly checklist and countdown timer. This was marginally effective, as sometimes, workers did not strictly adhere to timetables despite the aforementioned tools. Project status reports describe the completeness of various recurring tasks and assign percent completion to these tasks. An informal status reporting system was used for pool maintenance and was effective, as workers were always informed as to whether previous work had been completed, and whether to proceed with their own assigned tasks in proper succession.

Work Package 1: Alkalinity (TA) –ongoing, 3.5 months -Test twice-weekly using test strips (range 80-150 ppm) Test TA before testing for pH Dip test strip into water for 5 seconds Resources- test strips -Adjust TA level accordingly –ongoing, 3.5 months
If TA is too low, add product Alkalinity Control, if too high, add product pH Minus Resources- Alkalinity Control, pH Minus

Work Package 2: Maintain proper pH –ongoing, 3.5 months -Test twice-weekly using test strips Dip pH test strip into water for 5 seconds Resources- test strips -Adjust pH level according to test strip readings (range 7.4-1.8) If pH is too high, and TA is optimal, add product pH Minus If pH is too high and TA is also too high, see if TA adjustment also brings down pH Resources- pH test strips, pH Minus Work Package 3: Maintain proper calcium hardness –ongoing, 3.5 months -Test once monthly (range 200-400 ppm) Dip test strip into water for 5 seconds
Raise hardness with product Calcium Hardness Treatment; drain some water to lower hardness Resources- Calcium Hardness Treatment (Contributors, 2013)

Work Package 4: Sanitize pool water –ongoing, 3.5 months -Test for free chlorine with Nature2 CF system (target- 0.5 ppm)
Allow Nature2 CF system to operate until a reading has been recorded. Use Natur2 CF system to sanitize pool water (see appendix)

This essay and work breakdown structure represents the plan used for maintaining an aboveground pool for one entire summer. Since the pool has already been constructed, the work breakdown includes ongoing maintenance activities. A number of tools were used and evaluated for their effectiveness at completing the planned work. An appendix was also provided to further describe a more technical aspect of the maintenance work that was required for the overall task.
Use of Nature2 CF system for water sanitization will proceed according to what follows. Installation of the system consists in adding the Nature2 construction directly into the pool’s filter cartridge. The system works by attacking microorganisms that flow through the pool filter, which sanitizes the pool’s water. Water must be ‘balanced’ according to the specifications above with regard to all of pH, Alkalinity, and also calcium hardness. Once this has been accomplished, the Nature 2 CF system can be initialized. In order to use the system once it has been installed, the user must snap the two elements together, and insert it into the assembly mentioned above. This process will result in sanitized water.

Pert, Gantt Charts and Work Breakdown Structure

...of a Gantt chart (PM Hut, 2009). Diagram via  The Work Breakdown Structure A Work Breakdown Structure or WBS is a project management tool that is used for defining and organizing the total scope of a project by using a hierarchical tree structure. The first two levels of the WBS are called the root node and Level 2; Level-2 is often the most important because it determines how actual costs and schedule data are grouped for future project cost and schedule estimates. The WBS defines a set of planned outcomes that together represent 100% of the project scope instead of planned actions. Outcomes are the preferred ends of the project, such as a product, result, or service, and can be calculated exactly; actions however, may be difficult to predict accurately. A well-designed WBS makes it easy to assign any project activity to only one terminal element of the WBS. Each WBS element, when completed should contain four items; the scope of work including all deliverables, the beginning and end dates for the scope of work, the budget for the scope of work, and the name of the person responsible for the scope of work (Piscopo, 2013). Diagram via  One of the fundamental differences between a PERT chart and a Gantt chart is the way the information is presented. Gantt charts present information in the configuration of a bar chart.

...Comment Creer Un WBS Comment construire une structure WBS (Word Breakdown Structure) Un WBS ou structure WBS (Work Breakdown Structure) définit les objectifs d'un projet à tous ses niveaux de détail. Chaque niveau représente les composants mesurables qui doivent être fabriqués ou achevés afin d'atteindre l'objectif final, à savoir la réalisation et la livraison du produit. Le WBS a une structure hiérarchique : l'objectif situé en haut de la structure (niveau 1)représente l'ensemble du projet, alors que les niveaux inférieurs découpent le projet en composants et sous-composants de manière de plus en plus détaillée. Lors de la mise en place d'un WBS, il est important d'éviter de reproduire une structure de type organisationnelle ou fonctionnelle, dans la mesure où celles-ci ne sont pas fondées sur les résultats à atteindre. Les objectifs définis à tous les niveaux du WBS doivent au contraire représenter des résultats ou des livrables mesurables, en d'autres termes les composants du produit final à livrer au client à l'aboutissement du projet. Le WBS doit donc impérativement se limiter à définir les produits, sous-produits et services directement liés à ces résultats et livrables. La première étape de la gestion d'un projet consiste à créer le WBS. C'est en effet sur cette structure que se fonde toute la planification des processus et des échéances du projet. Ainsi, une fois le WBS mis en place, minutieusement vérifié et au besoin rectifié, il devient le document......

The structure illustrates the smaller units and allows for adaptation and quick communication if there a problems which need to be addressed. Definitions of each task should be clear and avoid overlapping in assignments. Defining the project scope The scope of a project is the end result, the deliverable or project end item. This is what will be basically used for planning and measuring the project. Defining the project scope is a definition of the outcome of the projects end result.

Wbs and Wbs Dictionary for Wedding

...Introduction The key to a good WBS and WBS Dictionary is the engagement of project team members to comprehensively identify and discuss activities for the project. A Project Manager must ensure that all the work that needs to be accomplished for the project is contained within the WBS Dictionary and is understood by team members. All work should have clearly defined duration, resources, dependencies, and level of effort (Cleland, 1990). A Project Manager should elicit feedback from all team members to ensure that the WBS and WBS Dictionary are valid and comprehensive prior to developing the detailed schedule. The project manager, has been asked to plan the wedding for his niece. Explain why you chose to organize your WBS in the manner you did. There are three reasons why the WBS is setup in the manner it is for this wedding project. The first is that is helps more accurately and specifically define and organize the scope of the total project. The most common way this is done is by using a hierarchical tree structure. See figure 1 below for a graphical representation of the WBS. The figure shows two level due to size of the project. Appendix A contains the WBS showing all three levels in a tabular format as a requisite for this assignment. Each level of this structure breaks the project deliverables or objectives down to more specific and measurable chunks. The second reason for using a WBS in your projects is to help with assigning responsibilities, resource......

Work Breakdown Structure

...Work Breakdown Structure (WBS) A work breakdown structure is a key project deliverable that organizes the team's work into manageable sections. The Project Management Body of Knowledge (PMBOK) defines the work breakdown structure as a "deliverable oriented hierarchical decomposition of the work to be executed by the project team." The work breakdown structure visually defines the scope into manageable chunks that a project team can understand, as each level of the work breakdown structure provides further definition and detail. An easy way to think about a work breakdown structure is as an outline or map of the specific project. A work breakdown structure starts with the project as the top level deliverable and is further decomposed into sub-deliverables using the following outline hierarchy. The project team creates the project work breakdown structure by identifying the major functional deliverables and subdividing those deliverables into smaller systems and sub-deliverables. These sub-deliverables are further decomposed until a single person can be assigned. At this level, the specific work packages required to produce the sub- deliverable are identified and grouped together. The work package represents the list of tasks or "to-dos" to produce the specific unit of work. If you've seen detailed project schedules, then you'll recognize the tasks under the work package as the "stuff" people need to complete by a specific time and within a specific level of effort.

Risk Breakdown

...An Introduction to the Risk Breakdown Structure When planning a project to meet targets for cost, schedule, or quality, it is useful to identify likely risks to the success of the project. A risk is any possible situation that is not planned for, but that, if it occurs, is likely to divert the project from its planned result. For example, an established project team plans for the work to be done by its staff, but there is the risk that an employee may unexpectedly leave the team. In Project Management, the Risk Management Process has the objectives of identifying, assessing, and managing risks, both positive and negative. All too often, project managers focus only on negative risk, however, good things can happen in a project, "things" that were foreseen, but not expressly planned. The objective of Risk Management is to predict risks, assess their likelihood and impact, and to actively plan what should be done ahead of time to best deal with situations when they occur. The risk management process usually occurs in five distinct steps: risk management planning, risk identification, risk analysis, risk response planning, and risk monitoring and control. The central point of risk identification and assessment in risk management is understanding the risk. However, this is also where project managers and risk subject matter experts (SMEs) get the least help from recognized references, best practices, or work standards. Currently, the Project Management Institute (PMIr) has......

This allows for the breakdown of the project’s deliverables into smaller, more detailed pieces. The following will provide a WBS based on a proposed project in week two about the improvement of lead flow for an uncontacted sales team. In addition to the WBS, this paper will discuss the importance of and identify the best approach to creating the WBS.
