book by DAMA, the Data Management Association. The DMBOK compiles data management principles and best practices.

       Synopsis - In this chapter, I will give an overview of why data is one of the key assets of an organization. To achieve this, I will first define the notions of data and asset. Then I will show what it means for data to be an asset. I will do this by stressing the relationship between processes (the “engine” of the organization), and data (the “fuel”) which are both needed to create value. I will illustrate the value of data through two short examples.

      So far, I have been using the word “data” colloquially without really defining it. Experience shows that people use the word differently so I will explore this concept first. On any such venture, the first step is to check a dictionary. The lemma for data from the Merriam-Webster Dictionary has three definitions:

      1. Factual information (such as measurements or statistics) used as a basis for reasoning, discussion, or calculation.

      2. Information in digital form that can be transmitted or processed.

      3. Information output by a sensing device or organ that includes both useful and irrelevant or redundant information and must be processed to be meaningful.

      These definitions are very similar to the way of thinking in the Design & Engineering Methodology for Organizations (DEMO) approach where a distinction is made between three levels of abstraction: forma - being all about documenting/ expressing facts and data; informa - being all about thought and reasoning; and finally performa - being all about using facts and data in the real-world, for example to decide on a course of action [RD99, Die06].

      Citing earlier work from the mid 1980s by Appleton, Peter Aiken - one of the eminent writers about DM - positions the term data in relation to other concepts such as facts and information [App86, AG13]. Figure 2.1 summarizes this way of thinking. One of the things that can be learned from this diagram is that data is said to consist of facts which have a meaning. Another important aspect is that data can be used, which shows intelligence. Comparing this approach to the previously cited definition, the question arises whether it is possible, or even useful, to clearly and unambiguously distinguish between the concepts of data and information: the Merriam-Webster Dictionary definition for data heavily relies on the notion of information and vice versa.

      For purposes of this book, I will not make a hard distinction between the two concepts. I will use the term data as an umbrella term, meaning all three definitions from the Merriam-Webster Dictionary. Even more, I intend to use it both as the “raw ingredient” (data codified in systems) and how it is used in business processes (sometimes called “information” by other authors). I will expand on this discussion further in chapter 6. Example 2 clarifies this way of thinking further.

       Example 2. Data management benefits

      Suppose you are an avid runner, like me. Your coach has explained that your heart rate provides a good indicator of how your body is doing and that it should be used to guide your bi-weekly training sessions. After purchasing a heart rate monitor, you go out for your first run.

      During your run, you can check your new gadget. It will measure how you are doing and individual data points are shown as you go along. Presumably, the gadget will also store this data, so that it can later be transferred to some online application for further processing. Together with your coach, you can use this data to analyze your fitness and training schedule for weeks to come.

      As stated in the opening paragraph of chapter 1: it is often said that “data is an asset”. For example, the DMBOK states [Hen17]:

       Data and information are not just assets in the sense that organizations invest in them in order to derive future value. Data and information are also vital to the day-to-day operations of most organizations. They have been called the “currency”, the “life blood” and even the “new oil” of the information economy. Whether or not an organization gets value from its analytics, it cannot even transact business without data.

      The question that needs to be answered is: what is an asset? Relying once more on the dictionary, an asset can be defined as “an item of value that is owned or possessed”. Let’s explore that further through the cases listed in example 3.

       Example 3. Examples of assets

      Assume the asset is a car. It has different types of value to me: it gets me from A to B, but it also has monetary value. Now assume that the asset is money. Its value is in the security that I have some buying power to take care of myself. Finally assume that the asset is customer data. Its value is that I know who my customers are, where they live and what they have purchased in the past so that I can help them well in the future.

      The examples show that assets can be tangible or intangible. They also show that assets have value. The latter point deserves further exploration. In previous research, I have shown that value is both personal (one person may see it differently than another person) and situational (in one situation it may be worth more than another) [Gil06]. Again, two small examples illustrate the point:

       Example 4. Value of assets

      The second example pertains to the value of water when compared to money. In most cases, I would value $10 over a small bottle of water. When standing in the middle of the desert, though, I may think differently. This shows the situational nature of valuation of assets.

      The implications for data as an asset are clear: when we say that we consider data to be an important asset then we mean that we believe that the data in our systems has much value, either intrinsic (we have data that is worth money, for example if we sell it) or indirectly
