Hi, Im a student of Computers Engineering https://www.ldc.usb.ve/%7Ecpc/ at Universidad Simón Bolívar http://www.usb.ve (Simon Bolivar University), in Caracas, Venezuela. I'm currently in my workgrade, it's about evaluating a few open source's tracking issue systems, with the intention of selecting the best one to extend its functionality. Under the evaluation's methodology (one designed in my university) i need to compare some information of the systems. I'm writing to know if there is any of the following items availables in some place, or if some one here can answer me. The items are this: * ¿Is there a software and system's requirements list defined by the developers or comunity developers? * ¿Does it exists a definition of the acceptance criteria? * ¿Is it defined a check criteria for all the software units with respect to the requirements? * ¿Does the software units were defined as the design? * ¿Does it exists a tests plain? * ¿How was the frequency of the tests plain? (half-yearly, quarterly, bi-monthly, per week, per day) * ¿Does it exists a check criteria to the product? * ¿Does it exists checking activities? * ¿What is the proportion between the functionalities that belongs to other systems and the total of the product's functionalities? * ¿How old, in months, is the software? (Since the first release) I would be preety grateful to anyone who could help me.
