Benchmarking has been enjoyed as one of the critical activities in the website development process and thus adopted very frequently at the requirement analysis phase in many website renewal as well as development projects. By comparing the services and features of the current website with those of competitors\` top-performing websites and figuring out their strengths and weaknesses, corporations can improve their website effectively. In spite of its importance and popularity, however, extant research shed little light on benchmarking for developing websites. This thesis proposes a benchmarking-based requirement analysis methodology for the improvement of websites that employs a goal-driven approach and considers both functional and nonfunctional requirements. To demonstrate the usefulness of our methodology, a real-life case of IR website of H Telecom Company is illustrated.
