Waterfall Approach And Requirement Uncertainties Essay


Discuss about the Waterfall Approach and Requirement Uncertainties.



The organization deals with multiple storage facility that is located around Australia. The project deals with the repairing works of three tanks in which leakage has been detected. Currently 30% of the company’s unleaded petrol storage capacity in Australia is bordering on collapse due to the age old condition of those three tanks and the associated infrastructure of the tanks. The condition of the largest tank is very critical and due to the detected leakage the company has been paying $20,000 per month as environmental fines. The project has been undertaken in order to repair the worn out condition of the tanks.


The identified goals of the project are as follows (Heagney, 2016)-

  1. Repairing all the tanks by fitting the required number of steel patches and steel anchors.
  2. Properly cleaning the tanks
  3. Repainting outside of the tanks

These are the basic goals identified for the project. In order to implement the project proper planning is required since the site is triangle in shape and direct access to tank 1 and tank 2 is quite difficult. In order to implement this project, waterfall project methodology is used as simultaneous working in all the tanks is impossible and therefore, it is better to follow a sequential approach of project management (Kerzner & Kerzner, 2017).

Project Scope

Scope Statement

The project deals with the repairing, cleaning and repainting all the tanks in order to reduce the environmental damage and prevent the collapse of the 30% of the company’s unleaded petrol storage capacity in Western Australia. Therefore, it is essential to implement the project as soon as possible. One of the major constraints of the project is that, the normal operation of the tanks cannot be hampered while implementation of the project and it is impossible for the workers and the team members to work on tanks at the time of their filling due to presence of the highly flammable vapours venting from the tanks. Furthermore, the internal access to the tanks is completely restricted by the pipelines and therefore, there is a need of using cranes and scaffolding for performing the repairing works on the tanks. Proper planning of the project work therefore becomes essential consideration of this project as any improper process might result in accidents.

The project will be implemented following a waterfall approach and therefore the resource requirement of the project calculated at the initiation phase of the project. In order to determine the scope of the project, several meetings have been help with the project team and the company members in order to select a particular project management approach and hatching out plans for successful project implementation in the constricted time when the tanks are not filling. The identified project scope will be followed throughout the project implementation phase.

Stakeholders Involved

For any project, it is essential to identify the different stakeholders associated with a project. The stakeholders identified for this project are represented below (De Brucker, Macharis & Verbeke, 2013)-

Stakeholder Description


Project Manager

The project manager is an important part of the project and therefore is an important stakeholder associated with the project. The project Manager is responsible for planning and successful implementation of the project and therefore, has a high interest in the project.

Health, Safety and Environment (HSE) Manager

The HSE Manager is an important stakeholder of a project as well. 30% of the company’s unleaded petrol capacity is on a verge of collapse as the detected leakage is causing a lot of environmental damage. This stakeholder has a great influence on the project and therefore considered as the important stakeholder of the project.

Western Australian Storage Facility

It is a major stakeholder of the project and it is the company that will be highly benefited with the implementation of this project. The detected leakage is the reason for the collapse of the 30% of the company’s storage capacity and therefore, this stakeholder has a high influence in the project.

The Revenue Division of Australia

The revenue division is an important project stakeholder associated with a project as it has developed the business case for the project

Team members

This is a needed yet less important stakeholder associated with the project.

Project Deliverables

The major deliverables of the project are as follows (Walker, 2015)-

  1. Completion of work in Tank 3- fitting 6 steel patches and anchors
  2. Completion of work in Tank2- Fitting 7 steel patches and 4 steel anchors
  3. Completion of work in Tank 1- Fitting 4 steel patches and 4 steel anchors
  4. Cleaning and painting the outside of the tank

Acceptance Criteria of the Project

The project will be accepted only after fulfilling certain criteria-

  1. The tanks do not posses any leakage after the project completion
  2. Proper cleaning of tanks after repairing the leakage
  3. The tanks have been painted within the set project schedule.

The Project Overview

The overall process of project implementation

With the proper identification of the scope and the project goals, it should not be a problem to implement the project in a planned approach (Kerzner, 2017). Although the geographical location and the structure of the tanks increases the complexity of the project, the use of proper cranes and scaffolding is expected to solve the accessibility problem associated with the Tank 2 and Tank 1. The largest Tank, which is tank number 3 is directly accessible from the road and therefore, it is better to complete the work of the tank 3 at first followed by the tank 2 and tank 1 (Mir & Pinnington, 2014). The waterfall project methodology chosen indicates that the project will be implemented in a sequential approach that is completion of one work marks the beginning of the next (Ru?l, Bondarouk & Smink, 2012). The details about the project life cycle and the project stages are discussed in the following section.

Project Life Cycle

The project undertaken follows a planned approach of project implementation. Development of a project plan indicates that the project will follow a strategic approach throughout its implementation phase. The different stages of the life cycle of the project are as follows (Larson & Gray, 2013)-

  1. Requirement Analysis and Project Plan- This stage is one of the major stages of project implementation and deals with the planning of the different resource requirement along with the project schedule.
  2. Project Implementation- Start of the work in tank 3 followed by tank 2 and tank 1.
  3. Cleaning and repainting the tanks
  4. Project handover
  5. Resource Release and payment completion
  6. Client sign off

Presence of a supervisor helps in proper implementation of a project and proper supervision is need for this project as the implementation of this project is quite risky (McLeod, Doolin & MacDonell, 2012).

Success Criteria

The success criteria of the project are as follows (Ru?l, Bondarouk & Smink, 2012)-

  1. The project is implemented within the allocated budget
  2. The leakage problem is solved with the project implementation
  3. The tanks are properly cleaned and painted
  4. No cases of accidents are found throughout the project implementation phase.

Successful implementation of the project is expected to reduce the leakage problem that is the major cause of depletion of the 30% of the unleaded petrol storage capacity of western Australia.
