Resource Breakdown Structure

Correct Answer: Revise the RBS and ensure resources match new role requirement

The best course of action when recognizing a need for a new role that wasn't identified in the original Resource Breakdown Structure (RBS) is to 'Revise the RBS and ensure resources match new role requirement'. The RBS establishes the team structure and roles for a project, hence adding new roles or revising the existing ones should be reflected in the RBS. Doing so would make sure that new or revised roles would have the appropriate resources as well. 'Ignoring the need for the new role' is not advised because it could lead to project delays, mistakes, or failure. 'Expecting existing resources to cover the new role' might also result in overloading the team and degrading the quality of work. 'Removing a different role to accommodate the new one' often is not feasible as every role in a project is significant and the removal of one role could lead to incomplete outcomes.

Correct Answer: Revise the RBS to provide clarity in roles and responsibilities ensuring proper resource allocations.

The best course of action amongst the options provided if the RBS (Resource Breakdown Structure) is not clearly defining the roles and responsibilities would be to revise the RBS for clarity. The RBS is a fundamental document in project management which ensures clear role definition, and allows for the appropriate allocation of resources, thereby mitigating risk associated with task overlap or omission. The other answer options are not best practices in project management. Assigning roles and responsibilities based on team member's personal preferences (as stated in the second answer) may not align with the skills necessary for project tasks, and can lead to inefficient resource allocation. Proceeding with the project assuming the team members will figure out their roles (as suggested in the third answer) can cause confusion and inefficiencies, leading to potential project failure. Finally, terminating the project until a new RBS is created (suggested in the fourth answer) is an extreme course of action that wastes time and resources without first attempting to revise the existing RBS.

Correct Answer: Consult with the IT department to refine and expand the IT resource categories in the RBS

The most effective next step in this scenario is to consult with the IT department to refine and expand the IT resource categories in the RBS. This approach is best because:

1. It directly addresses the identified issue of lacking clarity in specialized IT roles.
2. It leverages the expertise of the IT department, ensuring accurate and comprehensive categorization of IT resources.
3. It aligns with best practices in project management by involving relevant stakeholders in resource planning.
4. It allows for a more detailed and precise allocation of IT resources, which is crucial for an ERP implementation project.

Regarding the other options:

Completely restructuring the RBS to prioritize IT resources over all other types is an overreaction and could lead to an imbalanced resource allocation, potentially neglecting other important project areas.

Adding a general 'IT Specialist' category is too broad and doesn't solve the lack of clarity in specialized IT roles. This approach could lead to inefficient resource allocation and potential skill mismatches.

Proceeding with the current RBS and addressing IT resource allocation issues during project execution is reactive rather than proactive. This approach could lead to delays, inefficiencies, and potential resource conflicts during the critical implementation phase.

By consulting with the IT department to refine the RBS, the project manager ensures a more accurate, detailed, and effective resource plan, which is crucial for the success of an ERP implementation project.
