TIME TRACKING
A Time Tracking app initially developed for construction site workers to log work hours onsite, later extended to project managers and engineers to improve project planning.

My Role
My team consist of:
-
1 x product owner
-
2 x full-stack developers
-
1 x product designer (myself)
1 Project - 2 Challenges
I joined shortly before the beta phase to lead testing, onboarding, and refinements for Go-Live. After launch, the app was extended to PMs and engineers, which revealed new usability challenges that I addressed through feedback sessions, prototyping, and testing.
First Challenge: Beta Testing & Go-Live for on-site teams
The first challenge was making sure the app met workflow needs of solar fitters, electricians & site managers before go-live.
Go-Live Timeline
Creating a plan, I led the beta testing and gathered structured feedback by recruiting participants in ways that fit their context.
-
Site managers were only available for remote interviews.
-
Most solar fitters had no Teams accounts and were harder to reach, so I distributed surveys through team leads.
Beta testing planning & documentation
After the interviews & surverys, together with the team, the feedback was prioritized and improvements were made.
-
Example: Improved “Bad Weather” concept, enabling teams to log weather-related downtime efficiently.
Once improvements were integrated, I planned and conducted onboarding for solar fitter teams, AC/DC site managers, and electricians, ensuring smooth adoption during go-live.

Second Challenge: Adapting app for internal stakeholders
Following the successful launch, the app was extended to PMs and engineers. This created a new challenge, requiring adapting the tool to match their multi-project workflows, while keeping the mobile app and web version synchronized so the system stayed unified and consistent without fragmenting the product.
I conducted feedback sessions and interviews to validate the new problems (of inhouse PMs and enginners) and understand their frustrations with the current solution.
 This revealed six major challenges:
1
Duration instead of
start–end times → Logging total hours was faster than entering multiple sessions​
2
Adjust existing entries → Overlapping sessions made editing frustrating
​
3
Multiple project selection → Repetitive for users managing 20+ projects
​
4
Select project first → Users wanted to start with the project, then log time​
​
5
Role-based work types → Too many irrelevant options cluttered the workflow
​
6
Unnecessary clicks → Switching between work and travel created friction
​
Design Process
The new challenge required a design process focused on delivering fast, actionable results.

Iteration & Development
01 - Ideation & Feedback
I sketched solutions for project-first flow, multi-project logging, and quick editing, and reviewed ideas with PM, enginners and my team.
Concepts for various probem statements
02 - Prototyping & Testing
After gathering sufficient insights, I built two interactive prototypes exploring different workflows and tested them with five users (PMs and engineers). The clear winner was the project-first, duration-based entry with role-specific options.
Two example concepts with a winner
03 - Iteration & Delivery
As soon as a suitable concept was identified, I prepared handover to devlopers and supported them with reviews and testing during implementation. The developed version was thoroughly tested and reviewed by the team.

The Solution
The final UX that was delivered:
-
Web version of the app tailored to PMs and engineers.
-
Project-first workflow (choose project, then log time).
-
Duration-based entry instead of start-end.
-
Quick editing of existing entries.
-
Multi-project logging with fewer clicks.
-
Relevant work types displayed first.
-
Streamlined flow for back-to-back sessions.
Final web version of the Time Tracking app
Impact
-
Construction site teams successfully adopted the app, replacing the need for manual time tracking.
-
PMs and engineers’ needs were addressed with the revised flow, reducing frustration.
-
Improved efficiency, accuracy, and planning reliability for project management.
-
Management had consistent historical data for project planning and control.
Learnings & Reflections
-
A design that works for one group (fitters) may fail for another - user context is everything.
-
Iterative prototyping and quick usability tests were crucial to balancing simplicity and flexibility.
-
My biggest learning was finding the right balance: serving multi-project roles without overcomplicating the experience for single-project roles.
