As a guide in modeling the document labels using Latent Dirichlet allocation for archived documents in an Integrated Quality Assurance System (IQAS), the researchers used the agile method as it promotes flexibility, speed, and, most importantly, continuous improvement in developing, testing, documenting, and even after delivery of the software. Since the phases of this model are light, the teams are not bound by a rigid systematic-based process on pre-set constraints and restrictions as some other models, like the waterfall model, and can adjust changes whenever they are needed. This flexibility on every stage propagates creativity and freedom within processes. Furthermore, development teams can modify and re-prioritize the backlog, allowing for speedy implementation.
