Add These to Your Data Visualisation Repertoire

There are additional visualisation tools that you should be using to tell a better data story.  Each of these visualisation techniques serves specific purposes in data analysis, offering unique advantages for representing data insights.

Waterfall charts depict the impact of intermediate positive and negative values on an initial value, often resulting in a final value. They are commonly employed in financial analysis to illustrate the contribution of various factors to a total, making them ideal for visualising step-by-step financial contributions or tracking the cumulative effect of sequentially introduced factors.

Advantages:

• Sequential Analysis. Ideal for understanding the cumulative effect of sequentially introduced positive or negative values.
• Financial Reporting. Commonly used for financial statements to break down the contributions of various elements to a net result, such as revenues, costs, and profits over time.

Box and Whisker Plots summarise data distribution using a five-number summary: minimum, first quartile (Q1), median, third quartile (Q3), and maximum. They are valuable for showcasing data sample variations without relying on specific statistical assumptions. Box and Whisker Plots excel in comparing distributions across multiple groups or datasets, providing a concise overview of various statistics.

Advantages:

• Distribution Clarity. Provide a clear view of the data distribution, including its central tendency, variability, and skewness.
• Outlier Identification. Easily identify outliers, offering insights into the spread and symmetry of the data.

Bullet charts, a bar graph variant, serve as a replacement for dashboard gauges and meters. They showcase a primary measure alongside one or more other measures for context, such as a target or previous period’s performance, often incorporating qualitative ranges like poor, satisfactory, and good. Ideal for performance dashboards with limited space, bullet charts efficiently demonstrate progress towards goals.

Advantages:

• Compactness. Offer a compact and straightforward way to monitor performance against a target.
• Efficiency. More efficient than gauges and meters in dashboard design, as they take up less space and can display more information, making them ideal for comparing multiple measures.

Conclusion

Each data visualisation type has its unique strengths, making it better suited for certain types of data and analysis than others. The key to effective data visualisation lies in matching the visualisation type to your data’s specific needs, considering the story you want, to tell or the insights you aim to glean. Choosing the right data representation helps you to make informed decisions that enhance your data analysis and communication efforts.

Incorporating Waterfall Charts, Box and Whisker Plots, and Bullet Charts into the data visualisation toolkit allows for a broader range of insights to be derived from your data. From analysing financial data, comparing distributions, to tracking performance metrics, these additional types of visualisation can communicate complex data stories clearly and effectively. As with all data visualisation, the key is to choose the type that best matches the organisation’s data story, making it accessible and understandable to the audience.

#1 Build a Strategy around Voice & Omnichannel Orchestration

Customers seek flexibility to choose channels that suit their preferences, often switching between them. When channels are well-coordinated, customers enjoy consistent experiences, and CX teams and contact centre agents gain real-time insights into interactions, regardless of the chosen channel. This boosts key metrics like First Call Resolution (FCR) and reduces Average Handle Time (AHT).

This doesn’t diminish the significance of voice. Voice remains crucial, especially for understanding complex inquiries and providing an alternative when customers face persistent challenges on other channels. Regardless of the channel chosen, prioritising omnichannel orchestration is essential.

Ensure seamless orchestration from voice to back and front offices, including social channels, as customers switch between channels.

#2 Unify Customer Data through an Intelligent Data Hub

Accessing real-time, accurate data is essential for effective customer and agent engagement. However, organisations often face challenges with data silos and lack of interconnected data, hindering omnichannel experiences.

A Customer Data Platform (CDP) can eliminate data silos and provide actionable insights.

• Identify behavioural trends by understanding patterns to personalise interactions.
• Spot real-time customer issues across channels.
• Uncover compliance gaps and missed sales opportunities from unstructured data.
• Look at customer journeys to proactively address their needs and exceed expectations.

#3 Transform CX & EX with AI

GenAI and Large Language Models (LLMs) is revolutionising how brands address customer and employee challenges, boosting efficiency, and enhancing service quality.

Despite 62% of Singapore organisations investing in virtual assistants/conversational AI, many have yet to integrate emerging technologies to elevate their CX & EX capabilities. 

Agent Assist solutions provide real-time insights before customer interactions, optimising service delivery and saving time. With GenAI, they can automate mundane tasks like call summaries, freeing agents to focus on high-value tasks such as sales collaboration, proactive feedback management, personalised outbound calls, and upskilling.

Going beyond chatbots and Agent Assist solutions, predictive AI algorithms leverage customer data to forecast trends and optimise resource allocation. AI-driven identity validation swiftly confirms customer identities, mitigating fraud risks.

#4 Augment Existing Systems for Success

Despite the rise in digital interactions, many organisations struggle to fully modernise their legacy systems.

For those managing multiple disparate systems yet aiming to lead in CX transformation, a platform that integrates desired capabilities for holistic CX and EX experiences is vital.

A unified platform streamlines application management, ensuring cohesion, unified KPIs, enhanced security, simplified maintenance, and single sign-on for agents. This approach offers consistent experiences across channels and early issue detection, eliminating the need to navigate multiple applications or projects.

Capabilities that a platform should have:

• Programmable APIs to deliver messages across preferred social and messaging channels.  
• Modernisation of outdated IVRs with self-service automation.  
• Transformation of static mobile apps into engaging experience tools. 
• Fraud prevention across channels through immediate phone number verification APIs. 

#5 Focus on Proactive CX

In the new CX economy, organisations must meet customers on their terms, proactively engaging them before they initiate interactions. This will require organisations to re-evaluate all aspects of their CX delivery. 

• Redefine the Contact Centre. Transform it into an “Intelligent” Data Hub providing unified and connected experiences. Leverage intelligent APIs to proactively manage customer interactions seamlessly across journeys. 

• Reimagine the Agent’s Role. Empower agents to be AI-powered brand ambassadors, with access to prior and real-time interactions, instant decision-making abilities, and data-led knowledge bases.  

• Redesign the Channel and Brand Experience. Ensure consistent omnichannel experiences through data unification and coherency. Use programmable APIs to personalise conversations and identify customer preferences for real-time or asynchronous messaging. Incorporate innovative technologies such as video to enhance the channel experience. 

The White House has mandated federal agencies to conduct risk assessments on AI tools and appoint officers, including Chief Artificial Intelligence Officers (CAIOs), for oversight. This directive, led by the Office of Management and Budget (OMB), aims to modernise government AI adoption and promote responsible use. Agencies must integrate AI oversight into their core functions, ensuring safety, security, and ethical use. CAIOs will be tasked with assessing AI’s impact on civil rights and market competition. Agencies have until December 1, 2024, to address non-compliant AI uses, emphasising swift implementation.

How will this impact global AI adoption? Ecosystm analysts share their views.

The Larger Impact: Setting a Global Benchmark

This sets a potential global benchmark for AI governance, with the U.S. leading the way in responsible AI use, inspiring other nations to follow suit. The emphasis on transparency and accountability could boost public trust in AI applications worldwide.

The appointment of CAIOs across U.S. federal agencies marks a significant shift towards ethical AI development and application. Through mandated risk management practices, such as independent evaluations and real-world testing, the government recognises AI’s profound impact on rights, safety, and societal norms.

This isn’t merely a regulatory action; it’s a foundational shift towards embedding ethical and responsible AI at the heart of government operations. The balance struck between fostering innovation and ensuring public safety and rights protection is particularly noteworthy.

This initiative reflects a deep understanding of AI’s dual-edged nature – the potential to significantly benefit society, countered by its risks.

The Larger Impact: Blueprint for Risk Management

In what is likely a world first, AI brings together technology, legal, and policy leaders in a concerted effort to put guardrails around a new technology before a major disaster materialises. These efforts span from technology firms providing a form of legal assurance for use of their products (for example Microsoft’s Customer Copyright Commitment) to parliaments ratifying AI regulatory laws (such as the EU AI Act) to the current directive of installing AI accountability in US federal agencies just in the past few months.

It is universally accepted that AI needs risk management to be responsible and acceptable – installing an accountable C-suite role is another major step of AI risk mitigation.  

This is an interesting move for three reasons:

• The balance of innovation versus governance and risk management.
• Accountability mandates for each agency’s use of AI in a public and transparent manner.
• Transparency mandates regarding AI use cases and technologies, including those that may impact safety or rights.

Impact on the Private Sector: Greater Accountability

AI Governance is one of the rare occasions where government action moves faster than private sector. While the immediate pressure is now on US federal agencies (and there are 438 of them) to identify and appoint CAIOs, the announcement sends a clear signal to the private sector.

Following hot on the heels of recent AI legislation steps, it puts AI governance straight into the Boardroom. The air is getting very thin for enterprises still in denial that AI governance has advanced to strategic importance. And unlike the CFC ban in the Eighties (the Montreal protocol likely set the record for concerted global action) this time the technology providers are fully onboard.

There’s no excuse for delaying the acceleration of AI governance and establishing accountability for AI within organisations.

Impact on Tech Providers: More Engagement Opportunities

Technology vendors are poised to benefit from the medium to long-term acceleration of AI investment, especially those based in the U.S., given government agencies’ preferences for local sourcing.

In the short term, our advice to technology vendors and service partners is to actively engage with CAIOs in client agencies to identify existing AI usage in their tools and platforms, as well as algorithms implemented by consultants and service partners.

Once AI guardrails are established within agencies, tech providers and service partners can expedite investments by determining which of their platforms, tools, or capabilities comply with specific guardrails and which do not.

Impact on SE Asia: Promoting a Digital Innovation Hub

By 2030, Southeast Asia is poised to emerge as the world’s fourth-largest economy – much of that growth will be propelled by the adoption of AI and other emerging technologies.

The projected economic growth presents both challenges and opportunities, emphasizing the urgency for regional nations to enhance their AI governance frameworks and stay competitive with international standards. This initiative highlights the critical role of AI integration for private sector businesses in Southeast Asia, urging organizations to proactively address AI’s regulatory and ethical complexities. Furthermore, it has the potential to stimulate cross-border collaborations in AI governance and innovation, bridging the U.S., Southeast Asian nations, and the private sector.

It underscores the global interconnectedness of AI policy and its impact on regional economies and business practices.

By leading with a strategic approach to AI, the U.S. sets an example for Southeast Asia and the global business community to reevaluate their AI strategies, fostering a more unified and responsible global AI ecosystem.

The Risks

U.S. government agencies face the challenge of sourcing experts in  technology, legal frameworks, risk management, privacy regulations, civil rights, and security, while also identifying ongoing AI initiatives. Establishing a unified definition of AI and cataloguing processes involving ML, algorithms, or GenAI is essential, given AI’s integral role in organisational processes over the past two decades.

However, there’s a risk that focusing on AI governance may hinder adoption.

The role should prioritise establishing AI guardrails to expedite compliant initiatives while flagging those needing oversight. While these guardrails will facilitate “safe AI” investments, the documentation process could potentially delay progress.

The initiative also echoes a 20th-century mindset for a 21st-century dilemma. Hiring leaders and forming teams feel like a traditional approach. Today, organisations can increase productivity by considering AI and automation as initial solutions. Investing more time upfront to discover initiatives, set guardrails, and implement AI decision-making processes could significantly improve CAIO effectiveness from the outset.

Despite financial institutions’ unwavering efforts to safeguard their customers, scammers continually evolve to exploit advancements in technology. For example, the number of scams and cybercrimes reported to the police in Singapore increased by a staggering 49.6% to 50,376 at an estimated cost of USD 482M in 2023. GenAI represents the latest challenge to the industry, providing fraudsters with new avenues for deception.

Ecosystm research shows that BFSI organisations in Asia Pacific are spending more on technologies to authenticate customer identity and prevent fraud, than they are in their Know Your Customer (KYC) processes.

The Evolution of the Threat Landscape in BFSI

Synthetic Identity Fraud. This involves the creation of fictitious identities by combining real and fake information, distinct from traditional identity theft where personal data is stolen. These synthetic identities are then exploited to open fraudulent accounts, obtain credit, or engage in financial crimes, often evading detection due to their lack of association with real individuals. The Deloitte Centre for Financial Services predicts that synthetic identity fraud will result in USD 23B in losses by 2030. Synthetic fraud is posing significant challenges for financial institutions and law enforcement agencies, especially with the emergence of advanced technologies like GenAI being used to produce realistic documents blending genuine and false information, undermining Know Your Customer (KYC) protocols.

AI-Enhanced Phishing. Ecosystm research reveals that in Asia Pacific, 71% of customer interactions in BFSI occur across multiple digital channels, including mobile apps, emails, messaging, web chats, and conversational AI. In fact, 57% of organisations plan to further improve customer self-service capabilities to meet the demand for flexible and convenient service delivery. The proliferation of digital channels brings with it an increased risk of phishing attacks.

While these organisations continue to educate their customers on how to secure their accounts in a digital world, GenAI poses an escalating threat here as well. Phishing schemes will employ widely available LLMs to generate convincing text and even images. For many potential victims, misspellings and strangely worded appeals are the only hint that an email from their bank is not what it seems. The maturing of deepfake technology will also make it possible for malicious agents to create personalised voice and video attacks.

Identity Fraud Detection and Prevention

Although fraudsters are exploiting every new vulnerability, financial organisations also have new tools to protect their customers. Organisations should build a layered defence to prevent increasingly sophisticated attempts at fraud.

• Behavioural analytics. Using machine learning, financial organisations can differentiate between standard activities and suspicious behaviour at the account level. Data that can be analysed includes purchase patterns, unusual transaction values, VPN use, browser choice, log-in times, and impossible travel. Anomalies can be flagged, and additional security measures initiated to stem the attack.
• Passive authentication. Accounts can be protected even before password or biometric authentication by analysing additional data, such as phone number and IP address. This approach can be enhanced by comparing databases populated with the details of suspicious actors.
• SIM swap detection. SMS-based MFA is vulnerable to SIM swap attacks where a customer’s phone number is transferred to the fraudster’s own device. This can be prevented by using an authenticator app rather than SMS. Alternatively, SIM swap history can be detected before sending one-time passwords (OTPs).
• Breached password detection. Although customers are strongly discouraged to reuse passwords across sites, some inevitably will. By employing a service that maintains a database of credentials leaked during third-party breaches, it is possible to compare with active customer passwords and initiate a reset.
• Stronger biometrics. Phone-based fingerprint recognition has helped financial organisations safeguard against fraud and simplify the authentication experience. Advances in biometrics continue with recognition for faces, retina, iris, palm print, and voice making multimodal biometric protection possible. Liveness detection will grow in importance to combat against AI-generated content.
• Step-up validation. Authentication requirements can be differentiated according to risk level. Lower risk activities, such as balance check or internal transfer, may only require minimal authentication while higher risk ones, like international or cryptocurrency transactions may require a step up in validation. When anomalous behaviour is detected, even greater levels of security can be initiated.

Recommendations

1. Reduce friction. While it may be tempting to implement heavy handed approaches to prevent fraud, it is also important to minimise friction in the authentication system. Frustrated users may abandon services or find risky ways to circumvent security. An effective layered defence should act in the background to prevent attackers getting close.
2. AI Phishing Awareness. Even the savviest of customers could fall prey to advanced phishing attacks that are using GenAI. Social engineering at scale becomes increasingly more possible with each advance in AI. Monitor emerging global phishing activities and remind customers to be ever vigilant of more polished and personalised phishing attempts.
3. Deploy an authenticator app. Consider shifting away from OTP SMS as an MFA method and implement either an authenticator app or one embedded in the financial app instead.
4. Integrate authentication with fraud analytics. Select an authentication provider that can integrate its offering with analytics to identify fraud or unusual behaviour during account creation, log in, and transactions. The two systems should work in tandem.
5. Take a zero-trust approach. Protecting both customers and employees is critical, particularly in the hybrid work era. Implement zero trust tools to prevent employees from falling victim to malicious attacks and minimising damage if they do.

In my last Ecosystm Insights, I outlined various database options available to you. The challenge lies in selecting the right one. Selecting the right database is crucial for the success of any application or project. It involves understanding your data, the operations you’ll perform, scalability requirements, and more. Here is a guide that will walk you through key considerations and steps to choose the most suitable database from the list I shared last week.

Understand Your Data Model

Relational (RDBMS) vs. NoSQL. Choose RDBMS if your data is structured and relational, requiring complex queries and transactions with ACID (Atomicity, Consistency, Isolation, Durability) properties. Opt for NoSQL if you have unstructured or semi-structured data, need to scale horizontally, or require flexibility in your schema design.

Consider the Data Type and Usage

Document Databases are ideal for storing, retrieving, and managing document-oriented information. They’re great for content management systems, ecommerce applications, and handling semi-structured data like JSON, XML.

Key-Value Stores shine in scenarios where quick access to data is needed through a key. They’re perfect for caching and storing user sessions, configurations, or any scenario where the lookup is based on a unique key.

Wide-Column Stores offer flexibility and scalability for storing and querying large volumes of data across many servers, suitable for big data applications, real-time analytics, and high-speed transactions.

Graph Databases are designed for data intensely connected through relationships, ideal for social networks, recommendation engines, and fraud detection systems where relationships between data points are key.

Time-Series Databases are optimised for storing and querying sequential data points indexed in time order. Use them for monitoring systems, IoT applications, and financial trading systems where time-stamped data is critical.

Spatial Databases support spatial data types and queries, making them suitable for geographic information systems (GIS), location-based services, and applications requiring spatial indexing and querying capabilities.

Assess Performance and Scalability Needs

In-Memory Databases like Redis offer high throughput and low latency for scenarios requiring rapid access to data, such as caching, session storage, and real-time analytics.

Distributed Databases like Cassandra or CouchDB are designed to run across multiple machines, offering high availability, fault tolerance, and scalability for applications with global reach and massive scale.

Evaluate Consistency, Availability, and Partition Tolerance (CAP Theorem)

Understand the trade-offs between consistency, availability, and partition tolerance. For example, if your application requires strong consistency, consider databases that prioritise consistency and partition tolerance (CP) like MongoDB or relational databases. If availability is paramount, look towards databases that offer availability and partition tolerance (AP) like Cassandra or CouchDB.

Other Considerations

Check for Vendor Support and Community. Evaluate the support and stability offered by vendors or open-source communities. Established products like Oracle Database, Microsoft SQL Server, and open-source options like PostgreSQL and MongoDB have robust support and active communities.

Cost. Consider both initial and long-term costs, including licenses, hardware, maintenance, and scalability. Open-source databases can reduce upfront costs, but ensure you account for support and operational expenses.

Compliance and Security. Ensure the database complies with relevant regulations (GDPR, HIPAA, etc.) and offers robust security features to protect sensitive data.

Try Before You Decide. Prototype your application with shortlisted databases to evaluate their performance, ease of use, and compatibility with your application’s requirements.

Conclusion

Selecting the right database is a strategic decision that impacts your application’s functionality, performance, and scalability. By carefully considering your data model, type of data, performance needs, and other factors like cost, support, and security, you can identify the database that best fits your project’s needs. Always stay informed about the latest developments in database technologies to make educated decisions as your requirements evolve.
