Empathy / Research & Discovery

Objective: Deeply understand the context, needs, pain points, and behaviors of the target audience.

Actions: Conduct interviews, direct observation, market research, competitor analysis, and persona mapping.

02

Problem Definition

Objective: Synthesize collected data to clearly outline the core challenge to be solved.

Actions: Organize insights, create empathy maps, moodboards, and draft an objective problem statement to guide the project.

03

Ideation

Objective: Generate as many alternatives and creative pathways as possible without initial judgment.

Actions: Hold brainstorming sessions, rapid sketches, and explore different visual or conceptual references.

04

Prototyping

Objective: Turn abstract ideas into tangible, low-cost representations for visualization.

Actions: Build wireframes, mockups, or interactive prototypes.

05

Testing & Validation

Objective: Present the prototype to real users or stakeholders to gather feedback and measure solution effectiveness.

Actions: Conduct usability tests, observe reactions, identify friction points, and adjust as necessary.

06

Implementation (Execution)

Objective: Develop and launch the final version of the product.

Actions: Produce final deliverables, monitor the launch, and track metrics or ongoing user feedback.
