This interview with Yethi Consulting CEO Srirang Srikantha explores the critical role of quality assurance in the modern banking sector. Srikantha highlights how digital transformation has heightened customer expectations, making application speed and reliability more vital than traditional financial metrics for maintaining loyalty. He cautions financial institutions against over-relying on software vendors for system integrity, suggesting that independent testing is necessary to ensure flawless performance. The discussion further examines how full-stack observability and artificial intelligence can help manage the growing complexity of banking technology. Ultimately, the text presents a case for proactive performance validation to prevent costly technical failures and protect a bank’s reputation.

SPEAKER_00

Have you ever uh had that very specific moment of panic? You know the exact scenario I'm talking about.

SPEAKER_01

Well, yeah, I think we all do.

SPEAKER_00

You're just like standing in line at a grocery store, or maybe you're just sitting on your couch, right? And you open your banking app on your phone to quickly check your balance.

SPEAKER_01

You're just expecting the money to be there instantly.

SPEAKER_00

Right. Instantly. But instead the screen just goes white. Or uh there's just that tiny little spinning circle right in the middle of your screen.

SPEAKER_01

Skimming and spinning, yeah.

SPEAKER_00

One second goes by, then two, then three. And in that tiny, I mean, seemingly insignificant delay, your brain completely betrays you.

SPEAKER_01

It really does.

SPEAKER_00

You feel the sudden, completely irrational spike of adrenaline. Your mind just races to the worst-case scenario, like, was I hacked? Did someone steal my identity?

SPEAKER_01

Is my money just completely gone?

SPEAKER_00

Exactly. It is wild how, you know, three seconds of a blank screen can just completely unravel our entire sense of financial security.

SPEAKER_01

Yeah. It's a very visceral reaction, honestly. And uh it captures perfectly how our relationship with financial institutions has fundamentally shifted. I mean, we no longer separate the digital interface from the institution itself.

SPEAKER_00

Which brings us to today. Welcome to today's deep dive. We are exploring the invisible, highly fragile architecture of modern banking. It's a fascinating topic. It really is. Our source material today comes from a really insightful interview published in the July 2025 edition of the IBS Psy FinTech Journal.

SPEAKER_01

Right. The sit down with Shurang Shirkata.

SPEAKER_00

Yes, exactly. He's the CEO of Yeti Consulting. And they are this massive firm that specializes in quality assurance and uh application reliability for banks.

SPEAKER_01

Right, doing a lot of the heavy lifting behind the scenes.

SPEAKER_00

Right. So the mission of this deep dive is to understand why customer loyalty, which banks used to measure in you know decades, is now being measured in literal milliseconds.

SPEAKER_01

Literally milliseconds. It's crazy.

SPEAKER_00

It is. We're gonna look at why this massive push for digital transformation is exposing cracks in the financial system faster than ever before.

SPEAKER_01

Aaron Powell To set the stage for this, we should really look at how Robin Amlott framed the interview. Uh Amlot is the managing editor of IBS Intelligence.

SPEAKER_00

What did she say?

SPEAKER_01

He stated, now more than ever, your bank could be just one bad transaction away from loss of business and loss of value.

SPEAKER_00

Aaron Powell Wow. One bad transaction.

SPEAKER_01

Aaron Powell Yeah, that gets right to the core of the issue. In our current environment, a bank's reputation is inextricably tied to its technology.

SPEAKER_00

Right. They aren't separate things anymore.

SPEAKER_01

Exactly. If the technology hangs or fails, the bank itself fails in the eyes of the consumer.

SPEAKER_00

Aaron Powell Okay, let's unpack this because we really need to understand this entirely new metric of trust. Shrikantha points out a reality regarding customer patience that is just incredibly unforgiving.

SPEAKER_01

It really is. People have no patience anymore.

SPEAKER_00

None. If you open a banking app and it loads your accounts in, say, two seconds, you feel secure.

SPEAKER_01

You're right.

SPEAKER_00

It feels responsive and safe.

SPEAKER_01

Sure.

SPEAKER_00

But according to the data, if that exact same app asks you to wait for seven seconds, just five extra seconds, the user automatically assumes there's a systemic glitch.

SPEAKER_01

Seven seconds.

SPEAKER_00

Seven seconds. That is the threshold where a customer actively starts doubting the integrity of the actual bank.

SPEAKER_01

Aaron Powell What's fascinating here is that creeping doubt is highly destructive to a bank's core business model. I mean, Shrikantha notes that a new generation of customers is making decisions about where to park their money based on entirely different criteria.

SPEAKER_00

Aaron Powell Right. They aren't looking at the same things their parents did.

SPEAKER_01

No, not at all. They aren't pulling up the bank's tier one capital ratio to see if the institution has enough core equity reserves to survive a financial shock.

SPEAKER_00

Right. Nobody's doing that on their phone.

SPEAKER_01

Exactly. They aren't reading quarterly financial statements to verify the strengths of the actual balance sheet. They are evaluating the app.

SPEAKER_00

Just the app.

SPEAKER_01

Yeah, they want to know if the app is always available. And frankly, they want to know how sleek the user interface is.

SPEAKER_00

How cool it looks.

SPEAKER_01

Exactly. The actual financial reliability of the business has become totally secondary to the digital experience.

SPEAKER_00

I mean, that is a massive shift in human behavior. Historically, a bank proved it was safe by building, you know, a massive intimidating piece of architecture right in the middle of town.

SPEAKER_01

Like those giant stone buildings.

SPEAKER_00

Yeah. Giant marble columns, thick glass windows, and a heavy steel vault that you could physically see. That design was meant to communicate permanently.

SPEAKER_01

Right. It said we aren't going anywhere.

SPEAKER_00

Exactly. So it sounds like a banks app interface is basically the modern equivalent of that heavy steel vault. I mean, are are we really out here judging systemic financial stability by server load times?

SPEAKER_01

We absolutely are. And the reason why is that in the digital age, perception dictates reality.

SPEAKER_00

Perception is reality.

SPEAKER_01

Right. To the user sitting on their couch, the interface isn't just a window into the bank. The interface is the bank. Wow. If it's clunky or slow, the user implicitly believes the institution itself is clunky and unreliable. Performance is synonymous with institutional reliability. But uh that creates a glaring paradox, doesn't it?

SPEAKER_00

Well, if app speed and slick interfaces are the new gold standard, why are so many banks failing to deliver it?

SPEAKER_01

Uh right.

SPEAKER_00

With billions of dollars pouring into digital transformation across the financial sector, you'd assume these systems would be lightning fast. Are they just, you know, building bad technology?

SPEAKER_01

Well, no. It isn't necessarily that the new technology is inherently bad. Shrikantha argues that digital transformation isn't creating new problems out of thin air.

SPEAKER_00

Okay, then what is it doing?

SPEAKER_01

Rather, it's removing the historical time buffers that banks use to hide behind.

SPEAKER_00

Time buffers.

SPEAKER_01

Yeah, think about the mechanics of banking 15 years ago. If you needed to transfer money, you accepted the friction.

SPEAKER_00

Right. You had to actually go to the bank.

SPEAKER_01

Exactly. You drove to a physical branch, you stood in line, and you waited 20 minutes for a teller. Furthermore, you only checked your financial standing once a month when a paper statement arrived in the mail.

SPEAKER_00

Because the systems weren't real time back then. Right. Tellers batched transactions, and the bank ran these massive updates on their mainframes overnight.

SPEAKER_01

Precisely. That overnight batch processing and those 30-day statement cycles meant the bank had hours or even weeks to quietly fix internal errors.

SPEAKER_00

Oh, I see.

SPEAKER_01

They could reconcile mismatched accounts or correct computation mistakes completely out of sight. You, the consumer, never knew there was a problem because the bank fixed it behind the scenes before you ever saw the ledger.

SPEAKER_00

And today that buffer is completely gone.

SPEAKER_01

Entirely gone.

SPEAKER_00

We have real-time transaction-level transparency. When you hit transfer, an API like an application programming interface instantly calls the bank's database. If that database is locked up or struggling to compute, it doesn't just happen quietly in the background anymore.

SPEAKER_01

No, it's front and center.

SPEAKER_00

It's highlighted instantly on your screen as a spinning wheel or an error message. The customer sees the raw data processing in real time.

SPEAKER_01

And they panic.

SPEAKER_00

Right. And the source material gives a jarring anecdote about how badly this lack of a buffer can actually play out. Yeah. Shrikantha details the situation with a specific customer of Yethi. This bank decided to completely overhaul their system.

SPEAKER_01

Right. They chose a new architecture that put their customer relationship management system, their CRM, at the absolute center of their operation.

SPEAKER_00

It's just a huge change.

SPEAKER_01

It is. But here's the kicker they rolled it out without actually validating how the architecture would perform under a heavy load.

SPEAKER_00

And the consequences of skipping that validation were just severe.

SPEAKER_01

I can imagine.

SPEAKER_00

By putting the CRM at the heart of the system, it meant every single time a user tried to do anything like check a balance, send money, view a transaction, the system had to route through that customer profile database first.

SPEAKER_01

Aaron Powell So it became a massive bottleneck.

SPEAKER_00

Exactly. According to the interview, within 12 months of launching this architecture, the response time on their mobile app plummeted from a snappy 1.5 seconds down to an agonizing eight seconds.

SPEAKER_01

Oh man, which firmly crosses that seven-second threshold into the the bank is broken territory.

SPEAKER_00

But what happens next is the real tragedy of this anecdote. I mean, the bank spent heavily on this digital transformation to modernize, right? To push customers to the app. Right. But because the app took eight seconds to load, it eroded digital trust. Customers abandoned the app entirely.

SPEAKER_01

They just gave up on it.

SPEAKER_00

Yeah. And where do frustrated people go when they still need access to their money?

SPEAKER_01

Right back to the branch.

SPEAKER_00

They drove right back to the physical branches. They shifted the entire digital workload onto human tellers. The physical branches were suddenly overwhelmed by a massive influx of angry customers.

SPEAKER_01

It backfired completely.

SPEAKER_00

It literally destroyed the physical branch experience, too, which just completely defeats the purpose of the app.

SPEAKER_01

It really illustrates how digital transformation is a double-edged sword. I mean, it offers incredible convenience, but it demands unrelenting responsiveness.

SPEAKER_00

Yeah, people expect perfection.

SPEAKER_01

It leaves zero room for error. Think about it. When a customer is standing in a branch, a human teller can smile, apologize for a slow computer, and de-escalate the tension.

SPEAKER_00

Right. A little human empathy goes a long way.

SPEAKER_01

Exactly. But an app cannot apologize. It just hangs. Making post-launch corrections to these digital platforms is incredibly expensive, not just in terms of actual IT infrastructure costs, but the severe damage to the brand.

SPEAKER_00

So this brings up a major question about accountability then.

SPEAKER_01

Definitely.

SPEAKER_00

If rolling out an untested CRM can take down your app and flood your physical branches, why didn't the company that built the CRM test it first?

SPEAKER_01

So Shrakantha points out a dangerous misconception about that, particularly among smaller community banks in the U.S.

SPEAKER_00

What's the misconception?

SPEAKER_01

These institutions often operate under the assumption that the vendor, you know, the company that's sold on the platform owns the testing.

SPEAKER_00

They just assume it's handled.

SPEAKER_01

Right. Their attitude is I trust the vendor. They expect them to deliver working software.

SPEAKER_00

Aaron Powell, so what does this all mean? Shakantha views this reliance on the vendor as risky, really.

SPEAKER_01

Oh, very risky. He's very direct about this dynamic. We have to look at the incentives here. The OEM, the original equipment manufacturer who built the software, their primary goal is to sell the platform, deploy it, and move on to the next client. Aaron Powell Right.

SPEAKER_00

They want to close the deal.

SPEAKER_01

Aaron Ross Powell Exactly. But the bank's primary goal is to protect its reputation and its depositors' funds. Those incentives do not align at all.

SPEAKER_00

Aaron Powell I mean, it sounds like a bank buying a newly built house and just taking the builder's word that the plumbing is flawless.

SPEAKER_01

Aaron Powell That's a great way to put it.

SPEAKER_00

Like you wouldn't just skip the independent home inspection because the builder promises the pipes are fine, right? If you wouldn't blindly trust the builder of a house, why would an institution blindly trust a software vendor with billions of dollars in consumer deposit?

SPEAKER_01

You need the independent inspector precisely because they didn't build the house.

SPEAKER_00

Exactly.

SPEAKER_01

They have no financial incentive to hide a leaky pipe or pretend the structural flaw doesn't exist. Farantha stresses that an independent quality assurance team is vital, but their role is often really misunderstood in the industry.

SPEAKER_00

Misunderstood how?

SPEAKER_01

Well, they aren't just brought in to hunt for isolated bugs or to cynically prove the vendor made mistakes. The real task of professional QA is a meticulous, exhaustive process to affirmatively prove that everything works.

SPEAKER_00

Prove that everything works. I mean, that is a massive mandate. How do they actually do that?

SPEAKER_01

It requires verifying the software across multiple dimensions simultaneously.

SPEAKER_00

Okay, like what?

SPEAKER_01

First is the functionality correct. If you hit send, does the money actually move from account A to account B without vanishing into the ether?

SPEAKER_00

Aaron Powell That's pretty important. Yeah.

SPEAKER_01

Extremely. Second is the performance acceptable under stress. They simulate millions of concurrent users logging in on payday to ensure the system still responds in 1.5 seconds instead of eight seconds.

SPEAKER_00

Aaron Powell To avoid that CRM disaster.

SPEAKER_01

Exactly. And third is the security airtight. It's a rigorous process to establish true accountability.

SPEAKER_00

Aaron Powell But proving that everything works must be exponentially harder today than it was, say, 20 years ago.

SPEAKER_01

Oh, without a doubt.

SPEAKER_00

In the past, a bank might have just had one massive centralized mainframe doing all the math. But today, the underlying technology isn't just a single system anymore.

SPEAKER_01

No, it's highly fragmented.

SPEAKER_00

It's a tangled web of integrations. Srikantha actually notes that the number of technology components required to run a bank has been compounding rapidly for two decades.

SPEAKER_01

The complexity is staggering. We are talking about layers upon layers of distinct technologies communicating with each other.

SPEAKER_00

Right.

SPEAKER_01

You have the user interface on the mobile phone. Beneath that, you have the application stack, the microservices handling specific tasks, the operating systems, the databases holding the actual ledger, and the physical network architecture transmitting the data.

SPEAKER_00

Aaron Powell It's a lot of moving parts.

SPEAKER_01

And it gets more complicated because banks want to offer innovative features, they constantly plug in specialized third-party platforms.

SPEAKER_00

Aaron Powell Right, to stay competitive.

SPEAKER_01

Yeah. They integrate one API for customer onboarding, a different API for loan origination, and another entirely separate system for fraud detection.

SPEAKER_00

Aaron Powell And every new integration is a new risk.

SPEAKER_01

Aaron Powell Exactly. With every new integration, the number of potential failure points increases.

SPEAKER_00

Aaron Powell And when a system that complex breaks, it isn't obvious where the break actually happened, right? Not at all. If your transaction fails, did the app freeze? Did the fraud detection API time out? Did the legacy mainframe drop the connection?

SPEAKER_01

It could be any of them.

SPEAKER_00

Right. So to solve this, Rikanta introduces this concept of full stack observability. He describes taking all of these highly complex, disparate elements and bringing them into a single pane of glass.

SPEAKER_01

Aaron Powell A single pane of glass, yes.

SPEAKER_00

Aaron Powell But how does a single pane of glass actually track a transaction through all those different layers?

SPEAKER_01

Aaron Powell Well, full stack observability essentially attaches a digital tracking tag to a user's action and watches it travel through the entire nervous system of the bank.

SPEAKER_00

Okay, so it follows the data.

SPEAKER_01

Yes.

SPEAKER_00

Yeah.

SPEAKER_01

From the moment you tap your screen, observability tools monitor that specific data packet as it hits the API gateway, travels to the credit check service, and finally reaches the core database. That makes sense. So if the transaction hangs, the IT team doesn't just get a generic error message. They can look at that single pane of glass and see exactly which layer in the stack caused the bottleneck.

SPEAKER_00

Here's where it gets really interesting. Because it isn't just IT jargon, it translates the technical failure into actual business context.

SPEAKER_01

Aaron Powell Yes. And if we connect this to the bigger picture, that is the crucial distinction. Observability answers the so what of a system crash.

SPEAKER_00

The so what?

SPEAKER_01

Right. If a traditional dashboard flashes a warning that, say, server four CPU is running at 100%, that is just a technical metric. Trevor Burrus, Jr.

SPEAKER_00

Right. It doesn't mean anything to the CEO.

SPEAKER_01

Aaron Powell Exactly. It doesn't tell the bank executives what is actually happening to the business. Full stack observability puts that metric into context.

SPEAKER_00

Aaron Powell, so what does it tell them instead?

SPEAKER_01

It tells the bank server four is overloaded. And because of that specific server, our retail payment processing is currently down, or our new account onboarding flow is completely stalled.

SPEAKER_00

Oh wow, that's a huge difference.

SPEAKER_01

Aaron Powell It really is. It allows the bank to triage a crisis based on the actual impact to the customer rather than just chasing blinking red lights and technical alarms.

SPEAKER_00

But honestly, if the underlying architecture is layering on top of itself and becoming this incredibly complex, I mean, human QA teams can't possibly test every single pathway manually anymore.

SPEAKER_01

Aaron Powell No, it's beyond human scale at this point.

SPEAKER_00

Right. Nor can human eyes constantly monitor that single pane of glass for every potential anomaly across thousands of servers. So at a certain point, doesn't a bank just have to hand all of this testing and observability over to artificial intelligence.

SPEAKER_01

That's the million-dollar question.

SPEAKER_00

Aaron Powell Because there is constant hype right now that AI is going to write the code, test the code, and basically make human engineers totally redundant.

SPEAKER_01

It is the natural question every industry is grappling with right now. But Shrikantha addresses this directly, and he provides a much needed reality check on what AI can actually do in this space.

SPEAKER_00

Aaron Powell Oh, really? What does he say?

SPEAKER_01

He acknowledges that the technology is highly capable, of course. I mean Yeti Consulting utilizes AI extensively. Roughly 25 to 30 percent of their audit design, the actual writing of the test scripts, is now generated through AI. That's a significant chunk. Aaron Powell It is. They've also taken the mundane, repetitive daily tasks that used to consume hundreds of human hours and automated them with bots.

SPEAKER_00

Okay, so it is replacing some human effort.

SPEAKER_01

Yes. But despite the global industry hype about AI autonomously navigating systems and figuring out what works, Strakantha firmly states that AI cannot operate in complete isolation.

SPEAKER_00

Wait, why not? If an AI can scan millions of lines of code and spot a numerical anomaly in a millisecond, why does it still need a human looking over its shoulder?

SPEAKER_01

Aaron Powell Because spotting a technical anomaly is entirely different from understanding the consequence of that anomaly in the real world.

SPEAKER_00

Okay, that makes sense.

SPEAKER_01

AI is a pattern matching engine. It might see a sudden spike in database timeouts and flag it as an error, but it takes a human being with domain expertise to look at that flag and understand the actual context.

SPEAKER_00

Aaron Powell Like what kind of context?

SPEAKER_01

Well, the human knows that it's the 15th of the month. A major local industry just processed his payroll, and the system is actually operating exactly as expected under a localized heavy load.

SPEAKER_00

Ah, so it's a false alarm that only a human would recognize.

SPEAKER_01

Exactly. AI lacks the live reality to understand how a technical glitch actually impacts a mother trying to pay for groceries or a small business waiting on a crucial loan approval.

SPEAKER_00

Aaron Powell So you're basically clarifying the core difference between raw data and context. AI might be able to spot an anomaly in a millisecond, but it still takes a human to understand if that anomaly actually impacts the banking customer's experience.

SPEAKER_01

Aaron Powell This raises an important question about the balance of tools versus expertise.

SPEAKER_00

Aaron Powell Right, because Yeti operates at a massive scale, don't they? Trevor Burrus, Jr.

SPEAKER_01

Huge scale. They work with 140 banks across 35 countries, and they have expertise covering over 300 distinct banking applications.

SPEAKER_00

Wow. You can't just manage the cultural and regulatory nuances of 35 different countries with just an algorithm.

SPEAKER_01

Not a chance. AI can write a test script to see if a password box functions, sure. But it doesn't know what an intuitive mortgage application feels like to a first-time home buyer.

SPEAKER_00

Which really highlights the necessary balance here. AI is an incredibly powerful mechanism to help humans process data at scale and hold software vendors accountable.

SPEAKER_01

Yes, accountability is key.

SPEAKER_00

But it is the human understanding of the banking domains, the regulatory environment, and the ultimate business goals that makes the tool actually effective.

SPEAKER_01

Exactly. The AI does the heavy lifting on the data processing, but the humans provide the compass to interpret what that data means for the end user.

SPEAKER_00

Well, we have covered a significant amount of ground today.

SPEAKER_01

We really have.

SPEAKER_00

We have traced the evolution of financial trust from a physical reality, you know, standing in a marble lobby looking at a thick steel vault and reviewing paper statements once a month into a purely digital reality.

SPEAKER_01

It's a completely different world now.

SPEAKER_00

It is. We're now operating in an environment where a mere seven-second delay on a mobile app is enough to severely damage an institution's reputation.

SPEAKER_01

And cause them customers.

SPEAKER_00

Exactly. Digital transformation has completely removed the time buffers banks used to rely on, and it demands absolute real-time perfection. And we've seen how blindly trusting software vendors to test their own products is just a recipe for flooded physical branches and angry customers.

SPEAKER_01

Banks must rely on independent quality assurance to prove everything works.

SPEAKER_00

Right, everything.

SPEAKER_01

They need full stack observability to untangle the massive complexity of their systems and a hybrid approach where AI tools empower human banking experts.

SPEAKER_00

Absolutely. So the next time you open your banking app and it flawlessly loads your balances in a snappy two seconds, take a moment to consider what is actually happening behind the scenes.

SPEAKER_01

There's a lot going on.

SPEAKER_00

There is. Appreciate the intense, independent quality assurance, the real-time observability, tracing your data through a maze of legacy mainframes and modern microservices.

SPEAKER_01

All of it working together.

SPEAKER_00

And appreciate the hybrid AI human testing operating quietly behind that single pane of glass, just to keep you from feeling that sudden spike of panic.

SPEAKER_01

You know, as we wrap up, I want to leave you with a final forward-looking thought built on the source material.

SPEAKER_00

I'd love to hear it.

SPEAKER_01

Right now, modern banks are judged almost entirely by the visual aesthetic and the two-second load times of their mobile apps.

SPEAKER_00

Right. The screen is everything.

SPEAKER_01

But technology is continually evolving. What happens when banking becomes completely invisible?

SPEAKER_00

Invisible.

SPEAKER_01

Yes. We are moving rapidly toward a future where smart devices or autonomous AI assistants manage our transactions entirely in the background without us ever looking at a screen at all.

SPEAKER_00

Oh wow.

SPEAKER_01

So in a world where the interface disappears, will millisecond speed still be the ultimate metric of loyalty? Or will we need to invent an entirely new, unseen way to measure financial trust?

SPEAKER_00

That is wild to think about. I mean, if your digital assistant is doing the waiting for you, you might never even notice the seven second delay.

SPEAKER_01

Exactly. The metrics of trust will have to change again.

SPEAKER_00

It is a fascinating question to consider the next time you find yourself staring at that little spinning wheel. Thanks for joining us on this deep dive.
