Impact

Increased checkout rate by 67%

Overview

Grab and Ping An Good Doctor China introduced a telemedicine service for Indonesia market. GrabHealth offers online doctor consultations, medical purchases, and healthcare information.

Problem

Users added prescribed medications to their carts but didn’t complete their orders, resulting in a low checkout rate.

What concerns prevented users from completing their purchases after adding prescription medications to their carts?

How did I approach the problem?

To explore the problem space despite constraints, we conducted phone interviews with users.

  • Given the tight schedules and limited budget, we chose to run phone interviews as a fast way to understand why users weren’t checking out.

  • I was initially concerned that this might not be common practice in Indonesia and could offend users, but it turned out to be culturally acceptable.

  • Because of the language barrier, I partnered with the CS team to conduct the calls and shared interview tips to help them lead the conversations effectively

Initial research insights

Now we know why…

01

Users preferred buying drugs directly from brick-and-mortar pharmacies.

02

Many users already had the prescription drugs at home.

03

Some users thought med prices and delivery fees were expensive.

🤔

We learned that many users went to buy meds at brick-and-mortar pharmacies, but what was the reason behind the behavior?
(We'll find out later on…)

Proposed Design

Offer users alternatives to buy desired prescription drugs

For those who already had partial prescription drugs, I offered partial checkout; as a result, users were able to buy the meds needed only.

Checkout rate improved slightly, but not enough 🥲

Refining the approach

Conducted online survey to dive deeper underlying factors affecting purchase decisions

  • Conducted online surveys other than in-person user interview during the COVID-19 pandemic

  • Refined research goals to explore the entire customer journey, including consultation experience

  • Aimed to uncover all underlying factors affecting purchase decisions

Research insights

A few important takes

Wanted to save delivery time & delivery fee

24% of the users went to nearby pharmacies to buy meds due to delivery time and cost concerns

Had doubts about diagnosis or negative consultation experience

Negative consultation experiences decreased likelihood of purchase

Already had prescription drugs

16% of the users already had the prescription drugs at home

Proposed Design

Keep users informed with delivery time & prescription validity

For those who already have partial prescription drugs, I offer partial checkout, as a result, users are allowed to buy the meds they need only.
