Using SME to build a method for usability and accessibility evaluation in small software development companies.

Usability guarantees that a software application is effective, efficient, and satisfactory; meanwhile, accessibility ensures that the developed software can be used by all types of people regardless of their qualities and/or abilities. These two characteristics are key to providing quality software products. However, small software development companies do not have the personnel, knowledge, tools, and time necessary to carry out the evaluation process of these characteristics, resulting in the omission of these evaluations in the software development processes. The purpose of building a lightweight method is that within the software development process of small companies, it is possible to execute in a guided, simple, and correct way the usability and accessibility evaluations. For the construction of this method, the Situational Method Engineering-SME was used, resulting in the structure of the method, which consists of 5 activities with their respective tasks and formats, being subjected to expert evaluation validating its ease of use, usefulness, and completeness, obtaining as a result that it is a method moderately easy to use, useful, and complete, with elements of its structure that should be improved. Additionally, its ease of use and completeness were validated in a case study, obtaining an optimal response in the process.
