Estimating time for a project is quite challenging when UX design is not a linear process but includes a step-by-step process. Usually, it depends on the project type and characteristics to estimate the total time duration.
Generally, a UI UX design agency like ours may take a tentative duration of 2 weeks to 6 months for a UX design project to finish. Within this time period, we will go through a step-by-step process of actions that includes strategy, research, design, prototyping and usability testing.
This estimated timeline for an interface design company is perfect, from start to sitting for an initial meeting with the client to UX design deliverables. In case the end result needs more changes or clients seek more add-on solutions, the timeline will extend.
