For decades now, data has been sprinting its way up towards the leading edge of businesses. With the availability of sophisticated storage systems, it is now possible to store huge amounts of data generated by sales, customer interactions, and digital experiences. Mechanisms for easy integration of disparate systems, have ensured that enormous volumes of data are continually flooding the business world.
Data technologies have managed to tame this data into actionable insights. However, data is going to continue to spawn in the future. If exploited efficiently, massive repositories of data can provide a huge opportunity for businesses. This is where decision science comes in.
Decision science requires the ability to embrace data and utilize it in a manner that can help stakeholders arrive at critical business decisions. Utilizing data effectively to make informed business decisions translates to making intelligent inferences from data, creating effective stories, identifying relevant challenges, and then applying this knowledge correctly to the right set of problems in the business world.
A career in decision science involves creating solutions based on sound fundamentals of probability, forecasting, experimentation, and computational expertise.
Skills Required by Decision Scientists
Decision scientists require a combination of certain indispensable skills, which they use in collaboration to extract value from data and solve problems. These skills include the ability to use advanced knowledge of mathematics to understand patterns and trends. Then, statistical science helps to perform technical analysis of data based on patterns and trends.
Machine learning helps to assess possibilities galore and make predictions without human intervention. Further, decision scientists require business acumen, so they can perform an astute analysis of critical challenges and make important decisions to tackle them.
They play a very important role in using the data extracted from small pockets that exist in silos and assembling the chunks together, using the knowledge of business dynamics coupled with intuition and far-sightedness to create the big picture. In short, decision scientists are artists who combine the various sciences of maths, technology, and business for doing their job.

Role of Decision Scientist in Various Industries
The expertise of decision scientists is useful in many industries. These include driving sales in the retail industry, providing value to the banking industry, transforming the aviation industry, contributing to the healthcare industry, transportation, communication, education, and so many more. The kind of work that one can expect to do is described using the examples of retail and banking sectors.
As a decision scientist in the retail industry, you will see yourself using data for developing pricing strategies, discount techniques, and sales tactics. You will determine the right price points that would be favourable to a retail store and will contribute to the increase in revenue.
Similar contributions can be made in the areas of vendor management, inventory management, and store planning to arrive at important decisions such as the kinds of products that should be displayed together depending on the behaviour of consumers and their triggers for impulse purchases. Not only this, but you will also see yourself using trends in social media to analyze the interests of your customers and conducting marketing campaigns to drive sales.
In the banking industry, decision scientists use information about customer data and customer trends to categorize their clients. Based on customer lifetime value and other relevant factors, you will use predictive analysis to personalize services and products for diverse groups of your clients. This will also involve strategizing personalized marketing initiatives and relevant interactions to acquire as well as retain customers. Nevertheless, it will involve contribution towards designing products that can help achieve business growth.
Similarly, decision scientists play a major role in the areas of fraud prevention, and risk mitigation resulting in banks saving a huge amount of money. Huge customer data can be leveraged to understand, for example, the probability of fraud even before it is committed or chances of default on payments right at the stage of handing loans out.
Based on how customers in a specific group use technology, decision scientists ensure investments to optimize the development and use of appropriate technological systems to derive value. Demographics play an important role in this area. For example, in a specific region where there is a large population of young people who use their mobile phones for payments, a sound business strategy may require spending on the development and maintenance of a mobile application for the bank.
However, for a different group of customers, who do not have expertise in technology, are probably retired and have time may prefer personal interaction. Serving this group may mean the deployment of relationship management personnel to create satisfied customers and win brand loyalty. This may further extend to creating specialized products for a group that is highly likely to invest in specific financial products, thus promoting cross-selling.
