For a project in a remote rural area, especially one nearing completion, the most effective communication method with the local community would likely be through newspapers. This approach is suitable for reaching a broad audience in a locality where digital communication channels like social media or email may not be as accessible or frequently used. Newspapers are a traditional and reliable means of communication that can effectively convey important updates to all segments of the local population, including those who may not have access to or prefer not to use digital media.
References: The PMBOKGuide emphasizes the need to tailor communication methods to the stakeholders' needs and the context of the project1. It suggests that the format of communication should depend on the type of stakeholder, and various ways should be tailored to each group1. This is supported by the Professional in Business Analysis (PBA) reference materials, which advocate for the analysis of stakeholder needs and the selection of an engagement approach that best suits stakeholders' needs for effective communication and collaboration2.
