Informal communication is a type of communication that is casual, spontaneous, and unstructured. It does not
follow any predefined rules, protocols, or formats. Examples of informal communication include email, phone
calls, conversations in the hallway, and impromptu meetings12. The sponsor is using informal communication
to communicate with the team, as these methods are convenient, flexible, and personal. However, informal
communication may also have some drawbacks, such as lack of documentation, inconsistency, and potential
for misunderstanding3. Therefore, the sponsor should also use formal communication when necessary, such as
for official reports, contracts, and presentations4.

The statement of work (SOW) would clarify what the project implementation partner was contractually expected to complete after disagreeing with the project manager about completed requirements. A SOW is a document that defines the scope, deliverables, schedule, and terms and conditions of a project or contract. A SOW typically includes information such as purpose, scope of work, location of work, period of performance, deliverables schedule, applicable standards, acceptance criteria, special requirements, and payment schedule.
A SOW can help to establish a common understanding and agreement between the client and the service provider on what needs to be done and how it will be done.

Releasing the project resources is the process of formally ending the involvement of the project team members and other resources in the project. It also involves updating the resource availability andperformance records, and providing feedback and recognition to the resources. Releasing the project resources is an important part of the project closure phase, and it helps to avoid unnecessary costs and conflicts. If the project manager neglects to release the project resources, the team members may still charge time to the project and be unable to work on new projects12.

In response to new legislation requiring the release of contractors or their conversion to full-time employees, the project manager should prioritize compliance with the law. This may involve using only full-time employees, even if it results in project delays. The focus should be on legal compliance and the ethical treatment of workers, rather than solely on project timelines.

The execution phase is when the project manager and the team execute the project plan, deliver the project outputs, and monitor and control the project performance. This includes tracking and managing the project budget, scope, schedule, quality, and risks. Making adjustments to the budget based on the actual project expenditures is part of the monitoring and controlling process in the execution phase.
