The IT department of Wilmar International Ltd hired me to design an internal performance evaluation system for employees in their Singapore offices. Prior to this, they utilised paper forms. Common problems included: trouble tracking whose form submissions were outstanding, and manual processes due to the current paper-based system.
Stakeholder interviews, affinity mapping, prototyping (paper, mid-fidelity), usability testing.
The system was complex due to both the workflow required between the employees (Reviewees), managers (Reviewers), department heads (Countersigning Officers AKA COs), and HR.
To start, I interviewed employees from various departments in order to understand their pains and needs. After affinity mapping to identify commonalities, I began to create a paper prototype. After usability testing with 5 users, I iterated and created a mid-fidelity prototype. Further usability testing revealed a few modifications required, before delivering my final high-fidelity prototype to the client.
The client's developers used OutSystems to develop the application, which presented technical limitations. I regularly consulted with the IT project manager to make sure my designs were technically feasible in OutSystems.
I designed a performance evaluation system to fit the client's requirements while ensuring technical feasibility. My contribution to the project was completed within 10 weeks, delivering an interactive prototype and high-fidelity wireframes.
