Thai software requirements specification pattern

Although natural language has been widely accepted for writing software requirements specifications but writing skills are still needed for software engineers. Ambiguities are often encountered in requirements since software engineers do not have good writing skills or writing experience. In this study, we present a Thai software requirements specification pattern by using controlled syntax. Our pattern can help software engineers to answer the questions: “How to start writing software requirements specification?” and “What information should be gathered?”. Each component of the pattern is designed and described based on our controlled syntax.
