The crystal Crystal methodologies are a lightweight and versatile software development family of methods. Team size and project priority are the principal characterizations of crystal methods (Sambare, 2017; Tarwani & Chug, 2016). The methods were developed initially by Cockburn and are considered a lightweight development approach (Hohl et al., 2018) that promotes flexibility (Butt, 2016; Kulkarni, Padmanabham, Harshe, Baseer, & Patil, 2017). The crystal family of methods focuses on teamwork, flexibility, communication, and simplicity to improve processes (Kotaiah & Khalil, 2017).
The crystal Crystal family is identified by color to indicate the type of development. The colors include : clear, yellow, orange, and red (Kirmani, 2017a; Kulkarni et al., 2017; Sambare, 2017), indicating factors such as the team size of the team, the system criticality, and the priorities of the project (Fustik, 2017)project priorities. Color represents the weight or size of the project; the darker the color, the larger the project (Saravanan et al., 2017). Alqudah and Razali (2017) stated that crystal . Crystal orange denotes a project with around 40 developers, whereas crystal clear is more suitable for smaller projects with fewer developers. Additionally, crystal orange is more appropriate when a high degree of rigor is necessary, whereas clear is more flexible and lightweight (Alqudah & Razali, 2017). The color indicator of the method identifies the characteristics of the project and team and counter counters the one-size-fits-all ideals of other software development approaches.
The crystal method Crystal Method family provides projects with a framework designed for development size and criticality. Crystal is one of the more adaptable methodologies (Fustik, 2017; Kotaiah & Khalil, 2017), recognizing that each project may require individual policies and processes to meet the uniqueness of the project (Fustik, 2017; Sambare, 2017). The principles of crystal Crystal are passive knowledge transfer, continuous delivery, frequent releases, and automated testing (Hohl et al., 2018). The crystal family of methods arose from the need for an a customizable approach that was customizable to accommodate differences in projects.
