SINGAPORE: On Dec 21, 2020, a Singapore Airlines cargo aircraft landed at Changi carrying Singapore’s first batch of Pfizer-BioNTech COVID-19 vaccines.
Back then, native transmission of coronavirus circumstances had dropped to zero on most days. The most group dimension for social gatherings was about to go up from 5 to eight. Capacity limits at public locations would even be raised.
There was trigger for optimism and the arrival of the vaccines – with early outcomes indicating they have been extremely efficient towards COVID-19 – was one other shot within the arm.
But because the crates of vaccines have been slid out via the nostril of the Boeing 747 and whisked away to a chilly storage facility, authorities didn’t but say how they might be rolled out to the general public.
What was clear was that healthcare and important staff, in addition to weak sufferers and the aged, would get precedence.
Behind the scenes, Open Government Products (OGP) – an experimental tech improvement unit underneath the Government Technology Agency (GovTech) – started working. The mission: Build an appointment system in two weeks so everybody might begin getting vaccinated towards COVID-19.
Before the pandemic, OGP was already within the enterprise of rolling out easy but efficient tech options rapidly. It got here up with now-ubiquitous merchandise like the federal government kind constructing instrument FormSG and parking cost app Parking.sg.
OGP would go on to create at the least 5 COVID-19-related merchandise, like a stay-home discover reporting instrument, a case administration system and an informational web site on all issues COVID-19. Some of them are nonetheless in use at the moment.
Still, a vaccination appointment system introduced its personal challenges.
“At that time, it was fairly uncertain what was going to happen because there wasn’t a service model around vaccination roll-outs,” OGP deputy director Chan Chi Ling informed CNA.
Before there was an appointment system, the Ministry of Health (MOH) had deliberate the roll-out to be achieved in phases with extra handbook labour concerned, together with individually calling up those that have been eligible, she stated.
“Our team’s diagnosis was that we really needed a system that could do this at scale so it reaches millions of people within months,” she added.
First, the staff needed to take care of a number of requests from stakeholders throughout the Government, starting from whether or not individuals ought to ebook a time slot or location first, to extra difficult options like whether or not individuals might ebook as a household.
For the latter, engineers would have wanted to work with further information units like delivery and marriage information, including weeks to the venture timeline.
“For people who have not done software development before, it’s very hard to imagine how certain requests that seem innocuous can actually dramatically increase the timeline for a project,” OGP director Li Hongyi informed CNA.
“One thing that we’ve demonstrated that we can do is that if you need a solution quick, we can make something for you and we can put something together literally within like one or two weeks,” he stated.
So, Mr Li entered conferences with high-level authorities officers with clear goals: Strip away what he referred to as “nice-to-have” options and guarantee everybody was pulling in the identical path.
“MOH especially is quite a big ministry and there’s a lot of stakeholders, and even within MOH it takes time to get consensus,” he stated.
“I think a very big part of my role wasn’t so much about figuring out tech solutions, but explaining what the time trade-off is for any of these things. Because for COVID, even if you make a perfect system but it’s six months late – it’s useless.”
Back within the venture rooms, the OGP staff brainstormed a system sturdy sufficient to deal with tens of millions of bookings and clever sufficient to stop overcrowding on the vaccination centres. A system that crashes coupled with lengthy traces on the centres would undermine public belief.
“At the time, not everyone wanted to take the vaccine. There was a lot of vaccine hesitancy so the pressure also came from building a system that people trusted,” Ms Chan stated.
The further time strain made it “nerve-wracking”, she stated, declaring that the system additionally needed to be versatile to cater to MOH’s insurance policies, together with giving weak teams precedence.
One necessary issue was getting the triage web page proper to make sure solely those that have been medically eligible might ebook an appointment. These situations have been set by medical doctors, and included not being immunocompromised or having a historical past of anaphylaxis.
“Usually physicians have very precise terms, but they may not necessarily be understandable by members of the public,” Ms Chan stated, admitting she didn’t know what anaphylaxis was earlier than constructing the system.
“We have to find easy ways to explain what the terms are and make sure that the translations are there so that people of all languages can understand the medical triage.”
Still, Ms Chan recognised the medical significance of this. “Let’s say somebody gets cardiac arrest after taking the vaccine and our system didn’t filter them out accurately at the point of booking, then that’s not going to build public trust,” she stated.
The OGP staff had a number of exchanges with the medical doctors, and so they finally settled on a triage web page that was extra readable and “quite different from the first version”, she stated.
The staff additionally had to make sure the system was understood by the common person, so that they headed to the vaccination centres earlier than it was launched to get suggestions.
Ms Chan discovered some frequent questions among the many aged, together with whether or not they might take the vaccine if that they had different medical situations, like excessive ldl cholesterol or coronary heart issues.
“So, we realised that we had to develop a negative list – if you have this condition, it’s still okay to take the vaccine,” she added.
The staff additionally developed a separate system for social staff and volunteers to ebook appointment slots for seniors. These proxies might knock on seniors’ doorways and reply any queries they could have.
OGP rolled out the appointment system at the beginning of January 2021, assembly the deadline. Mr Li was happy with what the staff got here up with.
“A lot of other countries also had appointment systems, but because they didn’t design it quite right, when they opened their vaccine appointment system everyone charged in and it crashed,” he stated.
“Whereas ours from day one has been fairly strong. Maybe there’s a few hiccups however general, you get your SMS, you ebook your appointment, you present up, no fuss. There’s none of this nervousness about refreshing the web page and attempting to cost in.
“I think that was a really big deal and it gave people a lot of confidence.”
DELTA VARIANT HITS
As a lot as anybody would really like vaccines to be the pandemic’s panacea, actuality proved in any other case.
“We sort of thought the vaccination roll-out was going to be the end of it, but as with most COVID cases, it doesn’t quite work that way,” Ms Chan stated. “Post-vaccination, there were other new problems that emerged.”
When antigen fast testing turned the selection for routine testing among the many public, OGP constructed a registration system that might additionally seize the outcomes. Soon, the extra infectious and lethal Delta variant turned dominant, resulting in about 5,000 new circumstances a day at its peak.
Before this, when authorities have been anticipating solely a handful of latest circumstances every day, case administration was achieved utilizing Excel spreadsheets.
Once somebody examined optimistic, an MOH officer recorded their particulars on the spreadsheet and handed it on to a different officer who assessed their threat of growing extreme illness and whether or not they need to isolate at residence or be despatched to a facility. After this data was inserted, the sheet can be handed to a different officer in control of arranging the ability.
“And then they have to call you up, get your contacts and then they do the same thing for contacts in case they are quarantining them,” stated Ms Sonjia Yan, a senior product supervisor at OGP.
“So it’s as much as like 10 stages to this life cycle, and they will just pass the Excel sheets from one team to another.”
As circumstances spiked, it rapidly turned clear that this follow can be unsustainable. In the center of final yr, OGP was roped in once more.
“I think it was about 400 cases a day when we were brought in, and (case operations) were outfitted only for like 50 to 100 cases at most,” Ms Yan stated.
“The staff were really working overtime at 400 cases a day. So we really had to automate things very quickly so that they could free up staff to do the other duties.”

To shield hospital sources from being stretched, MOH launched the house restoration programme. But this created some frustrations amongst these being requested to get well at residence.
Some stated they may not get via to MOH for official recommendation, whereas others who have been informed they might be taken to a facility complained concerning the lengthy ready instances.
“That definitely was the impetus for us to jump in. One is just that we couldn’t process all the cases fast enough. And then the second one was that communications to the public were not very clear,” Ms Yan stated.
“The call centre was swamped with queries, and all their load populated down to the ops teams, because they had to ask the ops teams what is the status and get back.”
Ms Yan stated the OGP staff needed to “dive in” and study case operations from scratch. They had to make sure that officers might sustain with the sheer variety of circumstances, so that they “attacked” the step that was taking probably the most time.
The staff determined to make use of a customer support software program referred to as Zendesk – OGP’s “experimental” nature means it can use confirmed instruments available on the market to avoid wasting time – and customise it for case administration.
The system, finally named Zendemic, automates and tracks case operations. The system routinely updates itself when a affected person completes every step of the journey, from filling up a kind with their private particulars to being registered at a facility.
This implies that MOH officers, together with these on the name centre, might all log into the identical interface and get an instantaneous standing replace on a affected person. Zendemic additionally routinely sends a well being threat warning SMS to shut contacts, additional automating the contact tracing course of.
“Our goal was that whenever someone calls into the call centre with a query that can be resolved very quickly, like where is my grandmother now, the call centre should be able to respond immediately,” Ms Yan stated.
When every part was on Excel sheets, name centre officers must take down the query and name again as a result of they needed to go to the ops groups first, a course of that might take a day or extra, she stated.
“I think what really made a big difference was the call centre being able to just log into Zendesk and look at all the status updates of where this grandma is at and immediately just say, ‘Okay, she’s in the facility, don’t need to worry.’ That saves so much work for everybody involved.”
WEBSITE FOR ALL THINGS COVID
Beyond serving to the decision centre, OGP additionally determined to supply an informational COVID-19 web site, that broke down difficult insurance policies, introduced them merely and with infographics that have been simply shareable on social media.
This can be particularly for many who examined optimistic and have been uncertain what to do subsequent. The thought come after a gathering with a Singapore Armed Forces staff – which had been serving to out with COVID-19 operations – in October 2021.
OGP software program engineer Lam Kee Wei remembers that day, which was a Monday. He had not too long ago received married and was recent off a week of depart earlier than being thrown straight into the motion.
“It just shows OGP’s (way of working). Rather than put together a complete proposal, we just started working from day one and see what physical thing we can put out for approval,” he stated, including that his colleagues spent a number of days on the name centre engaged on it.
OGP instantly got down to discover what precisely individuals wished to know. The staff despatched out surveys, interviewed dad and mom and chatted with MOH officers within the name centre. They even embedded themselves in a Telegram chat group for these on quarantine.
“We talked to people on the Telegram channel, we talked to the admins, we read through the chats, we monitored the chat to see what people were saying as well,” OGP product designer Natalie Tan stated.
“We tried to cover as wide a range of personas as we could so that we will make sure that our solution was all-encompassing for all walks of life, essentially.”
This meant that they knew which phrases on the web site wanted tweaking, and have been capable of embrace different data like what relations of COVID-19 sufferers ought to do.
OGP constructed the web site, covid.gov.sg, utilizing its Isomer product – used broadly throughout the Government to rapidly construct standardised internet pages – and launched it lower than every week in a while Friday evening. Shortly after, it began getting good suggestions on the Telegram channel.
The staff began a thread of their Slack channel compiling the nice evaluations, together with optimistic messages from strangers in addition to household and associates, which Ms Tan stated was the inducement they wanted.
“At the point in time, everything was pretty hectic and the team was pretty high on stress and very low on sleep,” she stated.
“It just helped with the team’s motivation as well, to know that the work that we were actually doing was kind of paying off. We were really helping to make things a little bit easier for people, which was just very fulfilling for all of us.”
MAKING COMPROMISES
Mr Li stated he was happy with what the staff had achieved in Singapore’s response to COVID-19, highlighting that he had “too many people trying to work too hard”. “I didn’t have to push a single person,” he stated.
In reality, he needed to remind colleagues to take a breather after working full tilt for 2 weeks straight, stressing that they might not be working effectively in any other case.
This contains rejecting requests from authorities officers for brand spanking new options within the OGP merchandise, like integrating them with a hospital system. “It’s a really hard conversation to have, but it needs to happen because we just don’t have time to do everything,” he added.
The want to avoid wasting time additionally utilized to the query of how a lot safety must be put into their merchandise, particularly as they have been coping with issues like vaccination information. Mr Li stated making these merchandise absolutely safe might take one other two months.
“It’s not saying we don’t do things securely, but instead of going through the full (process), actually let’s just do a penetration test. Check to make sure that all our bases are covered – seems more or less right. We need to get it out,” he stated.
“And if something goes wrong, we’ll be ready to respond, but we need to go. After you get it out, then you go back and reinforce some of the mechanisms, but sometimes you do need to make trade-offs in terms of feature capability.”
These time financial savings have been precious contemplating the work OGP was already placing in to make sure its merchandise mirrored the consistently altering MOH insurance policies that developed with the dynamic COVID-19 state of affairs.
For occasion, the staff needed to overhaul the covid.gov.sg web site just a few days after launch when MOH stopped issuing quarantine orders for shut contacts.
OGP additionally needed to modify its back-end information alternate hyperlink, referred to as the COVID-19 administration spine, when MOH modified the definition of “fully vaccinated” to incorporate the Sinovac vaccine, or when the identical definition required a booster shot.
This is as a result of the general public’s digital vaccination information cross via this spine, which then applies what is known as enterprise logic to replace their vaccination standing in different merchandise for travelling or contact tracing.
While altering it’d appear to be simply altering a number of traces of code, Mr Lam stated the method was advanced as a result of many permutations concerned with completely different manufacturers and doses of vaccine.
“It was difficult to a point where we did consider making it an interview question for joining OGP, because it was just hard to get it out,” he stated.
Ultimately, Mr Li hopes to get extra funds to rent extra individuals for OGP, noting that COVID-19 has taken up most of its manpower, leaving its different merchandise with little to no help.
“To give you an idea of the order of magnitude, an average engineering team in most other places, in GovTech or whatever, there are 20 to 30 people for each module, like the Moments of Life or Singpass app,” he stated.
“Our team, the average team is like maybe two to three engineers, a product manager and like half a designer’s worth of time. And so it’s super lean.”
Mr Li stated the flexibility to “build good things quickly” is one thing the Government has not historically invested in, and that IT tasks have all the time been regarded as multi-month or multi-year endeavours.
“This idea of having a responsive task force that can set up solutions in days or weeks as opposed to months or years, was just not a thing that we really had,” he added.
“We’ve demonstrated that it can work. And not just us, but a few other teams in Government have done so as well.”
