Merixstudio’s team was responsible for the timely implementation of a clear-cut scope that mainly boiled down to empowering users to automate email marketing by generating custom forms and pages. Taking into consideration the scale and complexity of the whole application as well as a number of inherent dependencies, the team decided to pay a special focus on the testing process and to double QA efforts. Except for unit tests by the dev team, this mainly referred to QA functional testing i.e. writing numerous test cases and performing intensive manual testing, automated functional testing with WebdriverIO, JavaScript, Mocha, Chai as well as functional API testing with Postman.

We have composed a dedicated, self-managed team, including Scrum Master, UX designer, QA specialists, front-end and back-end engineers. The headcount varied between 7 and 10 as the team size was adjusted to the current project needs. The biggest extension concerned QA and UX teams, which resulted from the necessity to audit the client’s design and perform automated UI tests. More detailed information on team fluctuations is presented in the chart below.

One of the major challenges of the project was the effective remote cooperation of teams located in Poland, France and India. To successfully handle the workflow with an almost 5-hour time zone difference, all sides needed to understand the crucial role of communication and fully comply with the jointly agreed terms of cooperation. We achieved tangible results by harnessing the best Agile and Scrum practices, in particular:

  • organizing our work into 2-week sprints that synchronized planning-related activities, increased our focus and allowed us to update our thinking,
  • conducting daily meetings with dedicated people from all teams to keep up-to-date with the development process
  • setting up several channels on Slack to cover different topics for constant communication
  • keeping the essential information about tasks and processes in JIRA and Confluence
  • arranging regular reviews to demonstrate the effects of work, update the status of the project and collaborate on the plan ahead
