What type of communication can be considered a 'written notice' in a project context?

In a project context, a 'written notice' typically refers to a formal communication method that provides clear, documented information to the recipient. A formal letter is structured, precise, and often follows a specific format, making it suitable for conveying important project-related information, decisions, or changes. It serves as a formal record that can be referred back to if needed, ensuring clarity and accountability in communication.

The importance of formal letters lies in their ability to maintain a professional tone, establish a clear record of communications, and often be used for official notifications, contracts, or agreements. This aligns with the standards of professionalism and ethical practices in project management, where documentation is key for project tracking and accountability.

In contrast, informal emails, phone calls, and text messages lack the same level of formality and often do not provide the reassurance of a documented record that a formal letter does. Hence, while these other forms of communication can convey information, they do not meet the criteria of a 'written notice' as effectively as a formal letter does.
