CHAPTER 1
An Introduction to Big Data Governance
We are drowning in data today. This data comes from social media, telephone GPS signals, utility smart meters, RFID tags, digital pictures, and online videos, among other sources. IDC estimates that the amount of information in the digital universe exceeded 1.8 zettabytes (1.8 trillion gigabytes) in 2011 and is doubling every two years. Much of this data can be characterized as big data. Big data is generally referred to in the context of the "three Vs" — volume, velocity, and variety. We add another "V" for value. Let's consider each of these terms:
Volume (data at rest) — Big data is generally large. Enterprises are awash with data, easily amassing terabytes and petabytes of information, and even zettabytes in the future.
Velocity (data in motion) — Often time-sensitive, streaming data must be analyzed with millisecond response times to bolster real-time decisions.
Variety (data in many formats) — Big data includes structured, semi-structured, and unstructured data such as email, audio, video, clickstreams, log files, and biometrics.
Value (cost effectiveness) — Organizations are looking to gain insights from big data in a cost-effective manner. This is where open-source technologies such as Apache Hadoop have become extremely popular. Hadoop is software that processes large data sets across clusters of hundreds or thousands of computers in a cost-effective way.
Organizations must govern all this big data, which brings us to the subject of this book. We define big data governance as follows:
Big data governance is part of a broader information governance program that formulates policy relating to the optimization, privacy, and monetization of big data by aligning the objectives of multiple functions.
Let's decompose this definition into its main parts:
Big data is part of a broader information governance program. Information governance organizations should incorporate big data into their existing information governance frameworks by doing the following:
* Extend the scope of the information governance charter to include big data governance.
* Broaden the membership of the information governance council to include power users of big data such as data scientists.
* Appoint stewards for specific categories of big data such as social media.
* Align big data with information governance disciplines such as metadata, privacy, data quality, and master data.
Big data governance is about policy formulation.
Policy includes the written or unwritten declarations of how people should behave in a given situation. For example, a big data governance policy might state that an organization will not integrate a customer's Facebook profile into his or her master data record without that customer's informed consent.
Big data must be optimized.
Consider how organizations might apply the principles of the physical world to their big data. Companies have well-defined enterprise asset management programs to care for their machinery, aircraft, vehicles, and other assets. Similar to cataloging physical assets, organizations need to optimize their big data as follows:
* Metadata — Build information about inventories of big data.
* Data quality management — Cleanse big data just as companies conduct preventive maintenance on physical assets.
* Information lifecycle management — Archive and retire big data when it no longer makes sense to retain these massive volumes.
Privacy of big data is important.
Organizations also need to establish the appropriate policies to prevent the misuse of big data. Organizations need to consider the reputational, regulatory, and legal risks involved when handling social media, geolocation, biometric, and other forms of personally identifiable information.
Big data must be monetized.
Monetization is the process of converting an asset such as data into money by selling it to third parties or by using it to develop new services. Traditional accounting rules do not allow companies to treat information as a financial asset on their balance sheets unless purchased from external sources. Despite this conservative accounting treatment, organizations now recognize that they should treat big data as an enterprise asset with financial value. For example, operations departments can use sensor data to increase equipment uptime based on preventive maintenance programs. Call centers can analyze agents' notes to reduce call volumes by understanding why customers call. In addition, retailers can use master data to power Facebook apps that drive customer loyalty.
Big data exposes natural tensions across functions.
Big data governance needs to harmonize competing objectives across multiple functions. For example, the wireless marketing department at a telecommunications carrier might be interested in using geolocation data to drive new revenue streams, such as when a subscriber receives coupons from retailers that are in close proximity. However, the wireline business might be concerned about the reputational hazard associated with reusing subscribers' geolocation data without their consent. Meanwhile, the network management team might want to use this information to address any issues with network performance, such as a large number of dropped calls at a specific wireless tower. Finally, the chief privacy officer might have concerns about the potential for regulatory backlash. In this situation, big data governance needs to bring all the parties together to determine whether the potential revenue upside from the new services outweighs the associated reputational and regulatory risks. The usage of geolocation data for internal network analytics is probably okay, but the other business uses might not be.
Case Study 1.1 reviews the unfortunate events surrounding the Mars Climate Orbiter. We would not consider this volume of data to be "big" by today's standards. However, NASA likely produced the navigation commands by crunching some very big numbers with complex mathematics. If commercial organizations do similar crunching of big data to score a risk, fraud, or propensity to buy, they might incorrectly reject credit card applications or miss customer churn events because scores are misunderstood or applied incorrectly.
In a typical information governance project, the team identifies a business problem, develops a business case, obtains an executive sponsor, defines a technical architecture, and proceeds with the rest of the initiative. However, big data projects are different because of the following characteristics:
Projects are driven by early adopters.
The business problem needs to be discovered.
IT is often at the forefront with technologies such as Hadoop.
The business case has not been developed.
The characteristics of the data are unclear.
As of the publication of this book, governance has taken a backseat to the analytics and technologies associated with big data. However, as big data projects become mainstream, we anticipate that privacy, stewardship, data quality, metadata, and information lifecycle management will coalesce into an emerging imperative for big data governance.
CHAPTER 2The Big Data Governance Framework
This chapter provides a framework for big data governance. As shown in Figure 2.1, this framework consists of three dimensions:
Big data types — Big data governance needs a heightened focus on the data itself. We have classified big data into five distinct types: web and social media, machine-to-machine, big transaction data, biometrics, and human generated.
Information governance disciplines — The traditional disciplines of information governance also apply to big data. These disciplines are organization, metadata, privacy, data quality, business process integration, master data integration, and information lifecycle management.
Industries and functions — Big data analytics are driven by use cases that are specific to a given industry or function. Given space limitations, we have only included a handful in Figure 2.1. Big data analytics can be leveraged by many other industries and functions, including marketing, risk management, customer service, information security, information technology, and human resources.
We will discuss each dimension in this chapter.
2.1 Big Data Types
As shown in Figure 2.2, big data can be broadly classified into five types.
Let's consider each type in more detail:
1. Web and social media — This includes clickstream and social media data such as Facebook, Twitter, LinkedIn, and blogs. Big data governance programs will increasingly be required to integrate this data with master data and with core business processes such as customer loyalty programs. The big data governance program needs to establish policies regarding the acceptable use of social media data, especially since regulations and precedents are continually evolving. The program also needs to establish guidelines regarding the acceptable use of cookies, especially third-party cookies, to track users and to personalize their web interactions. Metadata is also critical to web and social media. For example, two sites might measure the term "unique visitors" differently for clickstream analytics. One site might measure unique visitors within a month, while the other might measure unique visitors within a week.
2. Machine-to-machine data — Machine-to-machine, or M2M, refers to technologies that allow both wireless and wired systems to communicate with other devices. M2M uses a device such as a sensor or meter to capture an event such as speed, temperature, pressure, flow, or salinity. This event is relayed through a wireless, wired, or hybrid network to an application that translates the captured event into meaningful information. M2M communications create the so-called "internet of things." The big data governance program needs to establish a number of policies around M2M data. For example, the program needs to draw up guidelines around the acceptable use of geolocation and RFID data that can be used to build a profile of individuals and potentially violate their privacy. The program needs to establish retention policies around the massive volumes of M2M data, which can easily overwhelm IT budgets if not properly controlled. The big data governance program needs to address any data quality concerns, such as RFID read rates in environments with high moisture content and lots of congestion. Finally, the big data governance program needs to secure the Supervisory Control and Data Acquisition (SCADA) infrastructure from vulnerability to cyber attacks.
3. Big transaction data — This includes healthcare claims, telecommunications call detail records (CDRs), and utility billing records. Big transaction data is increasingly available in semi-structured and unstructured formats. Information governance challenges such as metadata, data quality, privacy, and information lifecycle management also apply to this data.
4. Biometrics — Biometric recognition, or biometrics, refers to the automatic identification of a person based on his or her anatomical or behavioral characteristics or traits. Anatomical data is created from the physical characteristics of a person, including a fingerprint, an iris, a retina, a face, an outline of a hand, an ear shape, a voice pattern, DNA — even body odor. Behavioral data includes handwriting and keystroke analysis. Advances in technology have vastly increased the available biometric data. Law enforcement, the legal system, and intelligence agencies have been using this information for a long time. However, biometric data is increasingly available in the commercial arena, where it can be combined with other types of data such as social media. This opens up new business opportunities as well as several governance issues relating to privacy and data retention.
5. Human-generated data — Human beings generate vast quantities of data such as call center agents' notes, voice recordings, email, paper documents, surveys, and electronic medical records. This data might contain sensitive information that needs to be masked. It might also contain insights that can improve the quality of structured data sets and integrate with MDM. In addition to dealing with these issues, organizations need to establish policies regarding the retention period for this data to adhere to regulations and manage storage costs.
2.2 Information Governance Disciplines
The seven core disciplines of information governance also apply to big data:
1. Organization — The information governance organization needs to consider adding big data to its overall framework, including the charter, organization structure, and roles and responsibilities. The information governance council might seek new members who can provide a unique perspective on big data, such as data scientists. It might also decide to appoint stewards for social media, RFID, and other types of big data. Finally, the information governance program might add additional responsibilities to the job descriptions of existing stewards. For example, the customer data steward might be accountable for the Twitter handles and Facebook accounts within the master data repository.
2. Metadata — The big data governance program needs to integrate big data with the enterprise metadata repository. This involves the following activities:
* Include big data terms within the business glossary. For example, add the term "unique visitor" to support clickstream analytics.
* Import technical metadata from Hadoop into the metadata repository.
* Ensure that the data lineage administrator is able to import flows from Hadoop into the technical metadata repository.
* Manage data lineage and impact analysis within the big data environment.
3. Privacy — As far back as 1890, Louis Brandeis (later a justice of the United States Supreme Court) and Samuel Warren published an article called "The Right to Privacy" in the Harvard Law Review. This article defined privacy as the "right to be left alone." Subsequent regulations and legislation around the world have formalized and expanded this theory of privacy. Big data governance needs to identify sensitive data and establish policies regarding its acceptable use. These policies need to consider regulations that vary by big data type, industry, and country. Given the many headlines on the subject, the big data governance program needs to establish guidelines regarding the acceptable use of social media and geolocation data, if applicable.
4. Data quality — Data quality management is a discipline that includes the methods to measure, improve, and certify the quality and integrity of an organization's data. Because of its extreme volume, velocity, and variety, big data quality needs to be handled differently than traditional data types. For example, big data quality might need to be handled in real-time and address issues relating to semi-structured and unstructured data. Big data needs to be "good enough" because poor data quality does not necessarily impede the analytics that are required to derive business insights.
5. Business process integration — The program needs to identify key business processes that require big data. The program then needs to define key policies to support the governance of big data. For example, drilling and production are key processes within oil and gas. The big data governance program must establish policies around the retention period for sensor data such as temperature, flow, pressure, and salinity on an oil rig. Not only is this data costly to store, but it might also be required by regulators to justify an operator's actions in case of an oil spill. In another example, a retailer might establish a policy that it will access a customer's Facebook profile, including his or her list of friends, only if it has obtained informed consent via a Facebook app. The retailer will obtain the informed consent from the customer in exchange for discounts on certain products as part of an overall loyalty program.
