3.Top 10 Technology trends in 2020

4.Trend No. 1: Augmented analytics Augmented analytics automates finding and surfacing the most important insights or changes in the business to optimize decision making. It does this in a fraction of the time compared to manual approaches. Augmented analytics makes insights available to all business roles. While it reduces reliance on analytics, data science and machine learning experts, it will require increased data literacy across the organization. By 2020, augmented analytics will be a dominant driver of new purchases of analytics and business intelligence as well as data science and machine learning platforms.

5.Data to Analytics Challenge • Data preparation is huge effort • Data silos on different data platforms • Too many ad-hoc reports without single version of truth • Data Scientist is human, exhausted on repetitive work • A typical data analyst only analyzes a small portion (probably 10%)

6.Gartner Predicts: 2021 2022 75% of prebuilt reports Every personalized 30% of customer will be replaced with our interaction between interactions will be augmented by automated users and applications influenced by real-time insights delivered on a or devices will be location analysis, up “most needed” basis adaptive from 4% in 2017
