Strengths They declare and explain every things cleary since the system description til the functional requirements with understanding. Their requirements are easy to understand and there's are lots of detail. 1.Give the clear system description; and easy to understand; 2.clear definition of function and requirement ; 3.easy to understand function and it is very much detail on each requierment and function make it easy to understand They explain the requirement clearly. – use common vocabularies which are easy to read and understand. For requirement, it is separated in sub-topic so it’s easy to read and understandable with easy words - Explanation is clear and detailed; - Kept in mind that only one option (Bluetooth or 2G/3G) might be uncomfortable in such cases, and provided both options instead. Good and clear writing Easy to understand and lots of detail. Weaknesses If the system is OGC standard and use to find the thing, the sensor “must” not “may” to activate the device , if it not it will nothing because in normal we will off the any sensor in device that we not use so,the system must make it on to use ti find thing. If the sensor is off it not different to find by hands. This report is make me a little confuse with some of their functional requirement sentence. Not much description Inconsistently representing scope of their system between in perspective diagram and requirements.
