About the webinar
Insurance companies are looking at technology to solve complexity created by the presence of cumbersome processes and the presence of multiple entities like actuaries, support team and customers in the claim processing cycle.
Today, a lot of insurance companies are opting for Machine Learning to simplify and automate the processes to reduce fraudulent claims, predict underwriting risks, improve customer relationship management. This automated insurance claim process can remove excessive human intervention or manual errors and can report the claim, capture damage, update the system and communicate with the customers by itself. This leads to an effortless process enabling clients to file their claims without much hassle.
In this webinar, we will discuss how insurers are increasingly relying on machine learning to improve claim processing efficiency and increase ROI.
Fraud continues to proliferate across financial institutions, through multiple lines of business and banking channels. Increasingly sophisticated criminal tactics and the proliferation of organized crime rings make detecting fraud difficult and preventing it nearly impossible. Adding to the complexity is increased globalization and growth through mergers and acquisition, which make it harder to effectively monitor multiple portfolios and business lines. The presentation discussus best practices and ideas around the prevention, investigation, and detection of possible fraudulent activities across multiple industries.
Digital redefinition of banking banking transformationDraup
The increase in the number of digital use cases in the banking and financial services industry has led to the emergence of newer digital hotspots in the US. States such as Minnesota, North Carolina, Texas, and California have a high density of mature talent specializing in these digital cases. These digital use cases have also given rise to new hotspots in neighbouring states such as Iowa, Arizona, and Ohio. Bank of America, Wells Fargo, and JP Morgan Chase have capitalized on this rapid digitalization to create solutions in anti-money laundering, digital wealth management, information security, cloud technology.
Analysing the Digital Maturity of Top US Banks
The digital maturity of banks and financial institutions has been measured by their competency in innovation which includes their competitive intensity and growth potential and assessing their capabilities in terms of talent scalability and maturity of skills in new age technologies. By these parameters, firms such as Bank of America, Wells Fargo, Citi, and Capital One have identified as digital leaders while Union Bank, First Republic Bank, HSBC US have been relatively slower in the digital race.
Case-by-Case Analysis of Banking Transformation
Bank of America:
Bank of America has over 14 digital centres with over 76% of the digital talent based out of centres located in the US. The 4,000+ digital workforce is involved in functions such as app development, analytics, security, and cloud. Bank of America is one of the few leading banks looking to increase the digital capabilities of all its bank branches through interactive systems that need very little human intervention. Some branches are also fully automated equipped with an interactive teller machine and a video conferencing room.
Citi Group:
Citi is taking cues from its innovation labs that are involved in developing cutting-edge solutions such as beacons. The firm’s 3,500+ digital talent pool is predominantly based out of North America. The bank’s smart branches are equipped with interactive media walls that display local weather, stock information, and financial updates. Citi announced their partnership with Nasdaq which was formed to create payment systems that use DLT (Distributed Ledger Technology) to record payments.
Wells Fargo:
The firm’s large 7,500+ digital workforce is largely consolidated in the United States with sporadic distribution in India as well. The firm has 15 digital centres with only 2 of them located outside the US i.e. in Hyderabad, and Bengaluru. Over 28% of digital talent is involved in new-age solutions such as RPA, Blockchain, IoT and AI.

Straight Talk to Demystify Data LineageDATAVERSITY
Are you sure you trust the data you just used for that $10 million decision? To trust data authenticity we must first understand its lineage. However, the term "Data Lineage" itself is ambiguous since it is used in different contexts. "Business Lineage" links metadata constructs to specific terms in a business glossary. This approach is used by numerous Data Governance solutions. This approach alone comes up short, since it doesn't trace the real flow of information through an organization. "Technical Lineage" traces data's journey through different systems and data stores, providing an audit trail of the changes along the way. True "Data Lineage" combines both aspects, providing context to fully understand the data life cycle. Every step in data's journey is a potential source for introduction of error that could compromise Data Quality, and hence, business decisions. In this session, Ron Huizenga offers a comprehensive discussion of data lineage and associated Data Quality remediation approaches that are essential to build a foundation for Data Governance.

Business Process Analytics: From Insights to PredictionsMarlon Dumas
Keynote talk at the 13th Baltic Conference on Databases and Information Systems, Trakai, Lithuania, 2 July 2018.
Abstract
Business process analytics is a body of methods for analyzing data generated by the execution of business processes in order to extract insights about weaknesses and improvement opportunities, both at the tactical and operational levels. Tactical process analytics methods (also known as process mining) allow us to understand how a given business process is actually executed, if and how its execution deviates with respect to expected or normative pathways, and what factors contribute to poor process performance or undesirable outcomes. Meantime, operational process analytics methods allow us to monitor ongoing executions of a business process in order to predict future states and undesirable outcomes at runtime (predictive process monitoring). Existing methods in this space allow us to predict, for example, which task will be executed next in a case, when, and who will perform it? When will an ongoing case complete? What will its outcome be and how can negative outcomes be avoided? This keynote will present a framework for conceptualizing business process analytics methods and applications. The talk will provide an overview of state-of-art methods and tools in the field and will outline open challenges and research opportunities.

Case study on InnoVelocity's BPM implementation with JSR Micro, Inc. - a leading materials manufacturer. Delivered in conjunction with Nathaniel Palmer and featured on BPM.com
Continuous auditing and monitoring (“continuous reviews”) has been discussed for decades but implemented in moderation based on recent surveys. It comes down to how much are data analytics integrated into our audit processes initially to then become continuous. If a high degree of integration exists, then there is probably a good amount of continuous reviews happening in the organization already.
However, most companies fall into the other camp and have not integrated analytics well enough or considered how to take full advantage of continuous reviews.
This course will explain culturally what audit departments must do to embrace continuous reviews and how that can be integrated with ACL Desktop software techniques. Sample files and scripts will be provided to get you started down the road to continuous reviews.
As regulatory changes sweep the globe, auditors, risk management, and compliance professionals are using more sophisticated tools, and methods.

How GenAI will (not) change your business?Marlon Dumas
Not all new technology waves are the same. Some waves are vertical (3D printing, digital twins, blockchain) while others are horizontal (the PC in the 80s, the Web in the 90s). GenAI is a horizontal wave. The question is not if GenAI will impact my business, but what will be the scope of this impact. In this talk, we will go through a journey of collisions: GenAI colliding with customer service, clerical work, information search, content production, IT development, product design, and other knowledge work. A common thread to understand the impact of GenAI is to distinguish between descriptive use cases (search, summarize, expand, transcribe & translate) versus creative use.
Walking the Way from Process Mining to AI-Driven Process OptimizationMarlon Dumas
While generative AI grabs headlines, most organizations are yet to achieve continuous process improvement from predictive and prescriptive analytics.
Why? It’s largely about data, people, and a methodical approach to deploy AI to connect data and people. The good news is that if your organization has built a process mining capability, you are well placed to climb the ladder to achieve AI-driven process optimization. But to get there, you need a disciplined step-by-step approach along two tracks: a tactical management track and an operational management track.
First, it’s about predicting what will happen if you leave your process as-is, and what will happen if you implement a change in your process. At a tactical level, a predictive capability allows you to prioritize improvement opportunities. At an operational level, it allows you to predict issues, such as deadline violations. The challenges here are how to manage the inherent uncertainty of data-driven AI systems, and how to change your people and culture to manage processes proactively, rather than reactively. One thing is to deploy predictive dashboards, another entirely different thing is to get people to use them effectively to improve the processes.
Next, it’s about becoming preemptive: continuously optimizing your processes by leveraging streams of data-driven recommendations to trigger changes and actions. At the tactical level, this prescriptive capability allows you to implement the right changes to maximize competing KPIs. At the operational level, it means triggering interventions in your processes to “wow” customers and to meet SLAs in a cost-effective manner. The challenge here is how to help process owners, workers, and other stakeholders to understand the causes of performance issues and how the recommendations generated by the AI-driven optimization system will tackle those causes?
And finally, as an icing on the cake, generative AI allows you to produce improvement scenarios to adapt to external changes. Importantly, the transformative potential of generative AI in the context of process improvement does not come from its ability to provide question-and-answer interfaces to query data. It comes from its ability to support continuous process adaptation by generating and validating hypotheses based on a holistic view of your organization.
In this talk, we will discuss how organizations are driving sustainable business value by strategically layering predictive, prescriptive, and generative AI onto a process mining foundation, one brick at a time.

Discovery and Simulation of Business Processes with Probabilistic Resource Av...Marlon Dumas
In the field of business process simulation, the availability of resources is captured by assigning a calendar to each resource, e.g., Monday-Friday 9:00-18:00. Resources are assumed to be always available to perform activities during their calendar. This assumption often does not hold due to interruptions, breaks, or because resources time-share across multiple processes. A simulation model that captures availability via crisp time slots (a resource is either on or off during a slot) does not capture these behaviors, leading to inaccuracies in the simulation output. This paper presents a simulation approach wherein resource availability is modeled probabilistically. In this approach, each availability time slot is associated with a probability, allowing us to capture, for example, that a resource is available on Fridays between 14:00-15:00 with 90% probability and between 17:00-18:00 with 50% probability. The paper proposes an algorithm to discover probabilistic availability calendars from event logs. An empirical evaluation shows that simulation models with probabilistic calendars discovered from event logs, replicate the temporal distribution of activity instances and cycle times of a process more closely than simulation models with crisp calendars.

Can I Trust My Simulation Model? Measuring the Quality of Business Process Si...Marlon Dumas
Business Process Simulation (BPS) is an approach to analyze the performance of business processes under different scenarios. For example, BPS allows us to estimate what would be the cycle time of a process if one or more resources became unavailable. The starting point of BPS is a process model annotated with simulation parameters (a BPS model). BPS models may be manually designed, based on information collected from stakeholders and empirical observations, or automatically discovered from execution data. Regardless of its origin, a key question when using a BPS model is how to assess its quality. In this paper, we propose a collection of measures to evaluate the quality of a BPS model w.r.t. its ability to replicate the observed behavior of the process. We advocate an approach whereby different measures tackle different process perspectives. We evaluate the ability of the proposed measures to discern the impact of modifications to a BPS model, and their ability to uncover the relative strengths and weaknesses of two approaches for automated discovery of BPS models. The evaluation shows that the measures not only capture how close a BPS model is to the observed behavior, but they also help us to identify sources of discrepancies.

Business Process Optimization: Status and PerspectivesMarlon Dumas
For decades, business process optimization has been largely about art and craft (and sometimes wizardry). Apart from narrowly scoped approaches to optimize resource allocation (often assuming that workers behave like robots), a lot of business process optimization relies on high-level guidelines, with A/B testing for idea validation, which is hard to scale to complex processes. As a result, managers end up settling for a "good enough" process. Can we do more? In this talk, we review recent work on the use of high-fidelity simulation models discovered from execution data. The talk also explores the possibilities (and perils) that LLMs bring to the field of business process optimization.
This talk was delivered at the Workshop on Data-Driven Business Process Optimization at the BPM'2023 conference.
Learning When to Treat Business Processes: Prescriptive Process Monitoring wi...Marlon Dumas
Paper presentation at the 35th International Conference on Advanced Information Systems Engineering (CAiSE'2023).
Abstract.
Increasing the success rate of a process, i.e. the percentage of cases that end in a positive outcome, is a recurrent process improvement goal. At runtime, there are often certain actions (a.k.a. treatments) that workers may execute to lift the probability that a case ends in a positive outcome. For example, in a loan origination process, a possible treatment is to issue multiple loan offers to increase the probability that the customer takes a loan. Each treatment has a cost. Thus, when defining policies for prescribing treatments to cases, managers need to consider the net gain of the treatments. Also, the effect of a treatment varies over time: treating a case earlier may be more effective than later in a case. This paper presents a prescriptive monitoring method that automates this decision-making task. The method combines causal inference and reinforcement learning to learn treatment policies that maximize the net gain. The method leverages a conformal prediction technique to speed up the convergence of the reinforcement learning mechanism by separating cases that are likely to end up in a positive or negative outcome, from uncertain cases. An evaluation on two real-life datasets shows that the proposed method outperforms a state-of-the-art baseline.
Why am I Waiting Data-Driven Analysis of Waiting Times in Business ProcessesMarlon Dumas
Presentation of a research paper at the 35th International Conference on Advanced Information Systems Engineering (CAiSE) in Zaragoza Spain. The paper presents a classification of causes of waiting times in business processes and a method to automatically detect and quantify the presence of each of these causes in a business process recorded in an event log.
This talk introduces the concept of Augmented Business Process Management System: An ABPMS is a process-aware information system that relies on trustworthy AI technology to
reason and act upon data, within a set of restrictions, with the aim to continuously adapt and
improve a set of business processes with respect to one or more key performance indicators.
The talk describes the transition from existing process mining technology to AI-Augmented BPM as a pyramid, where predictive, prescriptive, conversational and reasoning capabilities are stacked up incrementally to reach the level of Augmented BPM.

Business Process Simulation with Differentiated Resources: Does it Make a Dif...Marlon Dumas
Existing methods for discovering business process simulation models from execution data (event logs) assume that all resources in a pool have the same performance and share the same availability calendars. This paper proposes a method for discovering simulation models, wherein each resource is treated as an individual entity, with its own performance and availability calendar. An evaluation shows that simulation models with differentiated resources more closely replicate the distributions of cycle times and the work rhythm in a process than models with undifferentiated resources.

Slides of a lecture delivered at the First Process Mining Summer School in Aachen, Germany, July 2022.
This lecture introduces techniques in the area of "task mining" with an emphasis on Robotic Process Mining. Robotic Process Mining (RPM) is a family of techniques to discover repetitive routines that can be automated using Robotic Process Automation (RPA) technology, by analyzing interactions between
one or more workers and one or more software applications, during the performance of one or more tasks in a business process. In general, RPM techniques take as input logs of User Interactions (UI logs). These UI logs are recorded while workers interact with one or more applications, typically desktop applications. Based on these logs, RPM techniques produce specifications of one or more routines that can be automated using RPA or related tools.
Accurate and Reliable What-If Analysis of Business Processes: Is it Achievable?Marlon Dumas
In this talk, I discuss the problem of how to discover simulation models that can be used to, accurately and reliably, predict the impact of a change on a business process, e.g. what-if we automate an activity? what-if 10% of our workers become unavailable? I focus on recent approaches that exploit the availability of data in enterprise systems to address this question.

Process Mining and AI for Continuous Process ImprovementMarlon Dumas
Talk delivered at BPM Day Rio Grande do Sul on 11 November 2021.
Abstract.
Process mining is a technology that marries methods from business process management and from data science, to support operational excellence and digital transformation. Process mining tools can transform data extracted from enterprise systems, into visualizations and reports that allow managers to improve organizational performance along different dimensions, such as efficiency, quality, and compliance. In this talk, we will give an overview of the capabilities of process mining tools, and we will illustrate the benefits of process mining via several case studies in the fields of insurance, manufacturing, and IT service management.

Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.
