The sprint A was started from the sprint planning and proceeded until the sprint review. The sprint B was started with a sprint backlog tested by usability testing and then followed by a sprint event until the sprint review. The sprint backlog for both sprints was the same because we wanted to compare and analyse the two sprints. The sprint backlog had three features as follows:
• Product information • Pricing information • Buying package
Both sprints have the same development team consists of two UI/UX designers and one senior developer. Therefore, we expected that the feature increments had the same product quality because of the same development team.
For the spring B, 1. after initial sprint backlog definition, the product owner conducted a usability testing for three features. For the usability testing, there were modification related to above features as follows: adding three sentences in Product Information, adding two information about Pricing, and adding a Buy Now button in the landing page. The aim of these additions is to test whether more information and direct navigation will ease potential customers to decide and buy the Angkasa LMS services.
This testing aims to rapidly analyse and validate user stories based on our testing participants¡¯ input. To gather information as the input of usability testing, we used a maze (https://t.maze.co/60719301?guerilla=true). In this research, we had total 7 testing participants (see Table 1).
Then for both sprints, these following steps were conducted.
Sprint reviews were conducted for the feature increments.
The incremented features, and user feedback were collected, compared, and analysed.
2n the sprint reviews, we conducted A/B Testing to compare and evaluate the feature increment between Sprint A dan Sprint B. The A/B testing was considered as a sprint review because in this testing, the participants were also asked to give inputs and select the better increment of the three tasks between the sprint A dan sprint B.
Of seven participants in the usability testing, only five agreed to participate in the A/B testing. We asked the participants to compare and select the best features from Sprint A (https://angkasa.rg.telkomuniversity.ac.id/clone1) and Sprint B (https://angkasa.rg.telkomuniversity.ac.id/clone2).
