Launching satellites is no longer a big deal for ISRO – it needs to set higher goals

We need to set the bar higher for India's space agency. It is among the very best and its successful PSLV launches are no longer big news.

Yesterday, India’s space agency ISRO set a new record by launching 104 satellites from a single launch vehicle. This is about three times what anyone had done before.

Make no mistake – this is a feat made possible by good engineering, a focus on precision and extensive simulations and modeling. The control systems teams at ISRO seem to be getting better and better at what they do. Evidently, the Polar Satellite Launch Vehicle or PSLV is a dependable launch vehicle, usually referred to by news articles as ISRO’s “workhorse”.

In response, there have been a big round of celebrations online and across the country. Lots of unqualified chest-thumping and proclamations about Indian greatness in engineering and in general. Typically, Indians could not unequivocally call themselves the best after any space-related achievement, because many missions and countries have been there before us. Therefore, the standard narrative was that India may not be the best, but certainly the least expensive and most efficient at getting to space. The “low cost” narrative has reigned supreme.

This time, there is a new twist to the low-cost narrative: that India can be a global leader on launching micro-satellites.

Here’s what the Hindustan Times said about the anticipated launch in its February 15 report:

The real significance of the launch, therefore, lies in the fact that it allows ISRO to test its capabilities for multiple launches of small satellites. This is crucial if India wants to grab a slice of the global market for nano and micro-satellites, which is set to grow close to $3 billion in the next three years. ISRO sources point out that some 3,000 satellites will be ready for launch in the next 10 years for navigation, maritime, surveillance and other space-based applications.

Here’s what The Ken said in its February 15 story:

With Isro planning to launch the PSLV more frequently, the rocket could be well placed to take advantage of the rapidly escalating numbers of small satellites that are looking to get into orbit.

Last year, the PSLV was second only to America’s Atlas V rocket in the number of 1–50kg class small satellites launched, according to the ‘2017 Nano/Microsatellite Market Forecast’ from SpaceWorks Enterprises, a US-based company that prepares assessments of global satellite activity. It predicts that nearly 2,400 such satellites “will require a launch from 2017 through 2023.”

Permit me to be the Grinch on this. Nobody likes damp squibs when others are happily celebrating, but a few points need to be raised.

Size matters

First, if nanosatellites are the future,  why is ISRO only launching others’ nanosatellites and not designing any of their own? If recent advancements in electronics have indeed made it possible to reduce the size of many satellites, shouldn’t ISRO also do what it can to reduce satellite sizes?

After all, every kilogram of matter that gets transported to the Low Earth Orbit costs several thousand dollars. Of course, not all satellites can be reduced in size. Transponders, high resolution cameras, and many other units still remain large in size and high quality and precision should trump size when they are necessary. Even so.

Second, is the PSLV really cost-effective and competitive? We really have no idea. As I wrote back in 2013:

[W]hen a French scientist was asked just after the 100th ISRO mission launched two French satellites, he remarked that they chose PSLV not because it was cheaper, but because the time slot available was convenient and because it was of comparable quality to other launchers. [Pragati, July 26, 2013]

It is clear that the PSLV is reliable and it is also obvious that ISRO will not get any business if they do not price their services competitively in the global market. But as we learn in Economics 101, price is not the same as cost.

ISRO has never put out detailed reports on how ISRO’s cost per kg to Low-Earth-Orbit compares to other space agencies. To the best of this author’s knowledge, only Space-X and other space agencies are actively trying to reduce the cost of payloads, by having some of the earlier rocket stages return to ground for re-use.

Third, as Gopal N Raj in The Ken notes, while nanosatellites are set to grow exponentially in number, they will not in terms of revenue for ISRO. A few, large satellite launches will still net higher revenues.

Fourth, we need to remember that we do not have a working alternative to the PSLV yet, and we aren’t doing enough space launches. ISRO is a national monopoly, even if it competes with other players globally. And there are signs that ISRO is suffering from the usual problems at the highest level that monopolies tend to face  – lethargy.

There is little evidence that ISRO’s space activities are sufficient for a growing economy like India’s. We need more commercial launches per year, more satellites in space per year (doesn’t matter who launches them), and more scientific missions per year. We need an ISRO with growing ambitions, and after the success of the Mars Orbiter Mission, there appears to be some bureaucratic action, with incremental target settings, and no real moonshot.

Space without constraints

In fact, the raison d’être of a state-run space programme is to do outrageous things that cannot be done by markets, to go beyond what is commercially feasible. A commercial satellite launch isn’t about going “boldly go where no mortal has gone before” to use Neil deGrasse Tyson’s adaptation of a popular phrase. ISRO needs to focus on the Moon and Mars and beyond, and open up commercial satellite launches to a domestic market.

The positive, long-term societal benefit of “crazy” space exploration is well documented. In an era where private individuals like Elon Musk can aspire to go to Mars, ISRO can aim even higher. (And ask for the budgets it needs.)

Fifth and finally, can we set a higher bar for ISRO? It is certainly a world-class organisation, it is competent and among the very best. This is a little unusual for a country which has to routinely deal with the mediocre. Successful launches of the PSLV are no longer news-worthy, they are to be expected of a competent space agency.

A country that has successfully launched a probe into Martian orbit doesn’t need to giddily celebrate every time we send a tonne of electronics a couple of hundred km above ground.

What hospitals can do to drive entrepreneurship and enhance patient experience

Hospitals can perform better by partnering with entrepreneurs and encouraging a culture of intrapreneurship focused on customer centricity.

At the Emory University Hospital in Atlanta, visitors don’t have to worry about navigating their way across the complex hospital premises. All they need to do is download wayfinding tools from the installed digital signage onto their smartphone and get step by step directions. Other hospitals have digital signage in surgical waiting rooms that share surgery updates with the anxious families waiting outside, or offer general information to visitors in waiting rooms. Many others use digital registration tools to reduce check-in time or have Smart TVs in patient rooms that serve educational and anxiety alleviating content.

Most of these tech enabled solutions have emerged as hospitals look for better ways to enhance patient experience – one of the top criteria in evaluating hospital performance. Patient experience accounts for 25% of a hospital’s Value-Based Purchasing (VBP) score as per the US government’s Centres for Medicare and Mediaid Services (CMS) programme. As a Mckinsey report says, hospitals need to break down a patient’s journey into various aspects, clinical and non-clinical, and seek ways of improving every touch point in the journey. As hospitals also need to focus on delivering quality healthcare, they are increasingly collaborating with entrepreneurs who offer such patient centric solutions or encouraging innovative intrapreneurship within the organization.

At the Hospital Leadership Summit hosted by Abbott, some of the speakers from diverse industry backgrounds brought up the role of entrepreneurship in order to deliver on patient experience.

Getting the best from collaborations

Speakers such as Dr Naresh Trehan, Chairman and Managing Director - Medanta Hospitals, and Meena Ganesh, CEO and MD - Portea Medical, who spoke at the panel discussion on “Are we fit for the world of new consumers?”, highlighted the importance of collaborating with entrepreneurs to fill the gaps in the patient experience eco system. As Dr Trehan says, “As healthcare service providers we are too steeped in our own work. So even though we may realize there are gaps in customer experience delivery, we don’t want to get distracted from our core job, which is healthcare delivery. We would rather leave the job of filling those gaps to an outsider who can do it well.”

Meena Ganesh shares a similar view when she says that entrepreneurs offer an outsider’s fresh perspective on the existing gaps in healthcare. They are therefore better equipped to offer disruptive technology solutions that put the customer right at the center. Her own venture, Portea Medical, was born out of a need in the hitherto unaddressed area of patient experience – quality home care.

There are enough examples of hospitals that have gained significantly by partnering with or investing in such ventures. For example, the Children’s Medical Centre in Dallas actively invests in tech startups to offer better care to its patients. One such startup produces sensors smaller than a grain of sand, that can be embedded in pills to alert caregivers if a medication has been taken or not. Another app delivers care givers at customers’ door step for check-ups. Providence St Joseph’s Health, that has medical centres across the U.S., has invested in a range of startups that address different patient needs – from patient feedback and wearable monitoring devices to remote video interpretation and surgical blood loss monitoring. UNC Hospital in North Carolina uses a change management platform developed by a startup in order to improve patient experience at its Emergency and Dermatology departments. The platform essentially comes with a friendly and non-intrusive way to gather patient feedback.

When intrapreneurship can lead to patient centric innovation

Hospitals can also encourage a culture of intrapreneurship within the organization. According to Meena Ganesh, this would mean building a ‘listening organization’ because as she says, listening and being open to new ideas leads to innovation. Santosh Desai, MD& CEO - Future Brands Ltd, who was also part of the panel discussion, feels that most innovations are a result of looking at “large cultural shifts, outside the frame of narrow business”. So hospitals will need to encourage enterprising professionals in the organization to observe behavior trends as part of the ideation process. Also, as Dr Ram Narain, Executive Director, Kokilaben Dhirubhai Ambani Hospital, points out, they will need to tell the employees who have the potential to drive innovative initiatives, “Do not fail, but if you fail, we still back you.” Innovative companies such as Google actively follow this practice, allowing employees to pick projects they are passionate about and work on them to deliver fresh solutions.

Realizing the need to encourage new ideas among employees to enhance patient experience, many healthcare enterprises are instituting innovative strategies. Henry Ford System, for example, began a system of rewarding great employee ideas. One internal contest was around clinical applications for wearable technology. The incentive was particularly attractive – a cash prize of $ 10,000 to the winners. Not surprisingly, the employees came up with some very innovative ideas that included: a system to record mobility of acute care patients through wearable trackers, health reminder system for elderly patients and mobile game interface with activity trackers to encourage children towards exercising. The employees admitted later that the exercise was so interesting that they would have participated in it even without a cash prize incentive.

Another example is Penn Medicine in Philadelphia which launched an ‘innovation tournament’ across the organization as part of its efforts to improve patient care. Participants worked with professors from Wharton Business School to prepare for the ideas challenge. More than 1,750 ideas were submitted by 1,400 participants, out of which 10 were selected. The focus was on getting ideas around the front end and some of the submitted ideas included:

  • Check-out management: Exclusive waiting rooms with TV, Internet and other facilities for patients waiting to be discharged so as to reduce space congestion and make their waiting time more comfortable.
  • Space for emotional privacy: An exclusive and friendly space for individuals and families to mourn the loss of dear ones in private.
  • Online patient organizer: A web based app that helps first time patients prepare better for their appointment by providing check lists for documents, medicines, etc to be carried and giving information regarding the hospital navigation, the consulting doctor etc.
  • Help for non-English speakers: Iconography cards to help non-English speaking patients express themselves and seek help in case of emergencies or other situations.

As Arlen Meyers, MD, President and CEO of the Society of Physician Entrepreneurs, says in a report, although many good ideas come from the front line, physicians must also be encouraged to think innovatively about patient experience. An academic study also builds a strong case to encourage intrapreneurship among nurses. Given they comprise a large part of the front-line staff for healthcare delivery, nurses should also be given the freedom to create and design innovative systems for improving patient experience.

According to a Harvard Business Review article quoted in a university study, employees who have the potential to be intrapreneurs, show some marked characteristics. These include a sense of ownership, perseverance, emotional intelligence and the ability to look at the big picture along with the desire, and ideas, to improve it. But trust and support of the management is essential to bringing out and taking the ideas forward.

Creating an environment conducive to innovation is the first step to bringing about innovation-driven outcomes. These were just some of the insights on healthcare management gleaned from the Hospital Leadership Summit hosted by Abbott. In over 150 countries, Abbott, which is among the top 100 global innovator companies, is working with hospitals and healthcare professionals to improve the quality of health services.
