Strengths They provide the information excellently.; I can understand what the system support to do and also the function what the system is required to do. clearly explaination and have many requirement Very detailed explanation. The document has strong attention to detail and well organized. Good for clients who love reading documents. First, the system description is clearly describe what is it and what does it use for.; Second, the requirement is clearly support the system description.; Third, each part of the requirement has been clearly described its function. Good idea,but how it different with Twitter, Twitter is not own system but is the way that people use to follow realtime news.The twitter is fix that the character is not more than 140 tap, it will fix to brief statement of the main points. but you have a record the word it will useful in future and know which new that people interest. They explain very clearly about what they will do and explain the system requirement clearly. Weaknesses - the features are interesting but should be more specific when describe each points.; - correct some grammar The objective is clear but the description is a bit confusing on the "analyze part." The diagram shows a lot of its features but its description are too short and not quite clear.. The weakness of TT3 is The system work with external storage. Little problem with the picture preferences, otherwise its fine.
