This document discusses 5 things that can waste time at work and introduces 5works as a potential solution. It outlines that while social networks like Facebook enable quick communication, they are not typically used for work due to privacy and organizational concerns. Email remains the main solution but can be formal, noisy, and lacks real-time conversation abilities. Instant messaging programs address some problems but have issues with chat logs and group conversations. The document then presents 5works as a private, file-sharing communication tool that supports one-to-one and one-to-many messaging as well as real-time updates and search in a web-based interface.
