But, where does an organization start?Motivation

Fortune 100 Contract Manufacturer Problem Domain 1: lots of data and data structures, a bunch

of stats, sql, and dashboard tools Problem Domain 2: just a few Ph.D.s (Lab & Praxis scientists

in mathematics, statistics, and data) w/ limited domain knowledge

Solution Domain: “Citizen” Data Scientists Gap1: Method to Conduct a full Data Science Project – How

do we attack a DS problem when we aren’t really sure what we will find or what an innovative solution will look like?

Gap2: Means to Evaluate ROI – How do we value what we create in DS? Is it only a fully implemented system like a typical IS/IT project?

The Essence of Data Science… Interdisciplinary, about processes and systems to extract knowledge or insights

from “interesting” data in various forms

structured & unstructured, private & public, samples & populations, “big” and “small” data

which is a continuation of some of the data analysis fields

such as statistics, data mining, and predictive analytics

and, can use processes like Knowledge Discovery in Databases (KDD) and CRISP-DM.

Data science employs techniques and theories drawn from many fields:

mathematics, statistics, information science, and computer science,

And includes signal processing, probability models, machine learning, statistical learning, data mining, database, data engineering, pattern recognition and learning, visualization, predictive analytics, uncertainty modeling, data warehousing, data compression, computer programming, artificial intelligence, and high performance computing.

And incorporates machine translation, speech recognition, robotics, search engines.

Data science is essential to the digital economy, and also the biological sciences, medical informatics, health care, social sciences and the humanities.

An integral part of competitive intelligence, a newly emerging field that encompasses a number of activities, such as data mining and data analysis.

The rise of Data Science in Organizations Massive “Interesting” Data

Firms are seeking to gain greater understanding of and insights into more and more massive quantities of data collected and stored in disparate public and private databases.

Data Science Tools & Technique Maturity

Data science tools and techniques have evolved rapidly over the last five years to analyze this structured and unstructured data from exploratory and confirmatory perspectives.

Desktop Accessible – Computational Power & User Friendly Interfaces

The data science tools themselves now run on readily available CPUs with much more user friendly interfaces that increase the use and usefulness of the tools to data scientists and domain expert alike.

Domain Knowledge Integral to DS Insights

As firms seek to maximize the utility of emerging data science technologies to organize and investigate more and more complex, massive data they are looking for innovative approaches to diffuse knowledge of the tools and techniques of data science to a “richer” set of users within domains.

Requires a Methodical Approach

To effectively and efficiently deploy project resources to the data science search activity and consequent build and evaluation of innovative artifacts, certain firms are finding that a Design Science approach can provide the iterative, evaluative method for the diagnosing, design, implementation, and evolution of data science artifact creation.

Critical to Competitive Intelligence

Several case examples exist to illustrate the Design Science method for investigating challenging data science problems that result in innovative solutions through the creation of a business process for the use of data science digital technologies.

No lack of Interesting Data Structured Private Data in Relational Databases within the Organization

Generally clean but not always connected databases

Almost always domain specific…

HR, Finance, Manufacturing, Supply Chain, Marketing or by Business Unit

Often access is controlled by an expert (in IT or in the Domain)

Standard reporting and sql processes are common

More and more often resides in private cloud platforms (ERP, CRM, etc.)

Unstructured Private Data in Non-SQL Databases within the Organization Including text, images, clickstream, posts, …

Limited standard reporting, difficult to search using traditional techniques

Often needs to be transformed to be productively explored

Often resides in cloud based data structures (ex: Hadoop)

Structured and Unstructured Data in Public data repositories Unstructured Social network unstructured data streams

Semi-structured Clickstream and IP/MAC addressable data streams

Structured data provided through various agencies and NGOs (CDC, DOT, etc)

Often dependent upon APIs and/or paid access

Usually only interesting when paid in “clever” ways with Private Data

A (Design Science) method to the (Data Science) madness… An Evidence Based Approach

Data Science has evolved to the point where its collective technologies can be relatively easily understood and deployed by any domain expert due to the “usual” evolution of a methodological approach, simplified interfaces, computing capacity, and access to data needed to move from the domain of the expert scientist to the praxis scientist.

Our analysis of the prior examples of the process of moving from research and science to problem solving and practice identified a logical evolution of technologies from the lab to the workbench. (ie: six sigma Motorola & GE)

From the Theoretical to the Practical

When this occurs, an innovative technology formed through research can be said to transition from the theoretical and into practical use by a wider set of engaged researchers and actual practitioners.

In so doing, the technology moves from the lab and into the practical application designed to solve real, sticky, wicked problems where those problems exist.

Creating competitive intelligence from inferences and hidden insights in massive data doesn’t happen by accident, it happens by Design!

A (Design Science) method to the (Data Science) madness…

Our work in situ with a Fortune 100 global advance manufacturing company used an action design research approach to co-develop a methodological approach to the conduct of big data science.

We identified, implemented and evaluated a data science method that can now be combined with the state-of-the-art GUI interfaces of various data science tools and existing computing capability to investigate massive data present in most organizations to allow organizations to truly develop scientifically sound inferences from the data.

We find that this transition to the scholarly practice of the data scientist can be accelerated through the application of the design science research method in an action research approach with practitioners.

And, that a combination of the engaged researcher and the scholarly practitioner generate knowledge that informs research and practice.

Example 1: Blog post engagement on the company site (10,000 unique blogs)

DIAGNOSIS DESIGN

Problem DomainStep 1•Thousands of blogs but no idea how to respond to each new blog and use to improve sales.

•Key insight: Blogs must be coming in from vendors, customers, potential customers, employees, potential employees, analysts, etc

•Marketing believes that “nurtured” leads with targeted content increase demand for that service by 20%

DataStep 2•External information: unique blogger identifying information•Internal: text content of blog, type of blog, page views, emails sent, number of visits

•Collect, clean, merge data, build data dictionary•Attributes include email address, country, lifecycle stage, emails opened, page views, social media clicks, and the text of the blog itself – entered in SQL & Hadoop

Text MiningStep 3•Rapid Miner – unsupervised associative rule cluster analysis•Multiple iterations to valid clustering model performance•Multiple iterations to supervise the grouping of clusters into “subscribers

Note: multiple iterations in each step often with different tools occurred.

Design Communication Strategies for each SegmentStep 1

•Five segments – Five strategies•Test each message with sample of blog subscribers•Complete A/B testing/experimentation

Design Automated Method to Classify Next Blog into a SegmentStep 2

Design Learning Algorithm to Measure Subscriber ReactionStep 3

Conclusion It’s Time for the Citizen Data Scientist:

The Data Science Tools have moved from the Lab to the Practice.

Citizen (Domain) Data (Variation in Interesting Data) Scientist (Methodical).

The User Interfaces make the Tools “Fungible” to Domain Experts

The Data Exists in exciting ways like never before (unstructured, populations, APIs, public)

Computing is (relatively) cheap and accessible to All.

The Method to Conduct Data Science Exists and can be taught and learned to improve project quality

Elaborated ADR Method – iterative, guided emergence, reflection, learning, to build and evaluate artifacts that make contributions to knowledge…

Citizen Data Science is a natural, complimentary – but different - progression from Deming Principles, TQM (Zero Defect), JIT (Eliminate Waste), Six Sigma (Eliminate Variation). Empower domain experts to explore, confirm, model, and instantiate systems that generate competitive

intelligence.

Learn to “Revel in the Variation”.

Use intelligent tools to see what is invisible to the human eye.

Digital Innovation results from the integration of DSR and DS. Provides the Method to conduct scientific investigation

Evidence of success through real projects with citizen data scientists.

Build a culture willing to explore and reward artifact generation to find hidden insights in “interesting” data.
