Some of the challenges that necessitate master data management are: Inconsistent data : With different versions of data available across organizational functions, locations, and systems, it can be difficult to maintain a single source of truth. Therefore, MDM is an ideal solution for all your data problems, and below are a few reasons why: Key business users can manage master data without having to wait for help from the IT department. Data stewards have the authority to approve or reject data from a central inbox.
As a result, data quality control relies completely on data stewards. A proper change request management can be put in place wherein any change in master data is made only after approval from the right authorities.
MDM enables centralized and de-centralized management of data. This means you can centrally manage data with a single owner of the master data, or de-centrally where master data is owned by multiple entities. Jerry Caous,. Back to overview. Also interesting.

Language English Spanish French. However, as mentioned in my initial statement, master data is actually the powerhouse that drives your dynamic data. At many companies, maintaining master data still reflect a highly manual task. Moreover, Excel spreadsheets are a prominent tool when it comes to master data maintenance.
Why is this a benefit? First of all, manual processes are always a source of failures and a driver of inefficiency. Secondly, and although Excel sheets are easy-to-use, they show massive disadvantages when it comes to exchanging data with other systems.
A centralized and system-based Master Data Management eliminates both of the issues. On the contrary, data governance processes should even restrict that approach. On top of that, master data system —usually— offers a broad range of integration possibilities. What are the reasons you consider important? I would be happy to receive your feedback and thoughts.
Just hit me up on Twitter or get in touch on LinkedIn. Benjamin is a content-maniac, music-lover, aviation-enthusiast, and CEO of Information Design in this order.
His daily business revolves around pioneering solutions to change the way airlines, airports, and aviators use information.
Lets say that that you have clear bounded contexts where dedicate teams are working within Said contextS, coupling it together with master data management will make the teams very slow. I would rather see that the team owned the data for each context so they can iterate faster. Your email address will not be published.
Because master data is used by multiple applications, an error in the data in one place can cause errors in all the applications that use it. An incorrect address in the customer master might mean orders, bills and marketing literature are all sent to the wrong address. Similarly, an incorrect price on an item master can be a marketing disaster and an incorrect account number in an account master can lead to huge fines or even jail time for the CEO—a career-limiting move for the person who made the mistake.
A credit card customer moves from North 9th St. The customer changed his billing address immediately but did not receive a bill for several months. One day, the customer received a threatening phone call from the credit card billing department asking why the bill has not been paid.
The customer verifies that they have the new address and the billing department verifies that the address on file is 11th St. The customer asks for a copy of the bill to settle the account. After two more weeks without a bill, the customer calls back and finds the account has been turned over to a collection agency.
This time, the customer finds out that even though the address in the file was 11th St. North, the billing address is listed as 11 th St. After several phone calls and letters between lawyers, the bill finally gets resolved and the credit card company has lost a customer for life.
In this case, the master copy of the data was accurate, but another copy of it was flawed. Master data must be both correct and consistent. Even if the master data has no errors, few organizations have just one set of master data.
Many companies grow through mergers and acquisitions, and each company that the parent organization acquires comes with its own customer master, item master and so forth. In most cases, customer numbers and part numbers are assigned by the software that creates the master records, so the chances of the same customer or the same product having the same identifier in both databases is pretty remote.
Item masters can be even harder to reconcile if equivalent parts are purchased from different vendors with different vendor numbers. Merging master lists together can be very difficult since the same customer may have different names, customer numbers, addresses and phone numbers in different databases. Smith and William Smithe. Normal database joins and searches will not be able to resolve these differences. A very sophisticated tool that understands nicknames, alternate spellings and typing errors will be required.
The tool will probably also have to recognize that different name variations can be resolved if they all live at the same address or have the same phone number. While creating a clean master list can be a daunting challenge, there are many positive benefits to the bottom line that come from having a common master list, including:. If you create a single customer service that communicates through well-defined XML messages, you may think you have defined a single view of your customers.
But if the same customer is stored in five databases with three different addresses and four different phone numbers, what will your customer service return? Similarly, if you decide to subscribe to a CRM service provided through SaaS, the service provider will need a list of customers for its database.
Which list will you send? For all of these reasons, maintaining a high quality, consistent set of master data for your organization is rapidly becoming a necessity. The systems and processes required to maintain this data are known as Master Data Management.
Master Data Management MDM is the technology, tools and processes that ensure master data is coordinated across the enterprise. MDM provides a unified master data service that provides accurate, consistent and complete master data across the enterprise and to business partners. Depending on the technology used, MDM may cover a single domain customers, products, locations or other or multiple domains. The benefits of multi-domain MDM include a consistent data stewardship experience, a minimized technology footprint, the ability to share reference data across domains, a lower total cost of ownership and a higher return on investment.
Before you get started with a master data management program, your MDM strategy should be built around these 6 disciplines:. While MDM is most effective when applied to all the master data in an organization, in many cases the risk and expense of an enterprise-wide effort are difficult to justify. PRO TIP: It is often easier to start with a few key sources of master data and expand the effort once success has been demonstrated and lessons have been learned. If you do start small, you should include an analysis of all the master data that you might eventually want to include in your program so that you do not make design decisions or tool choices that will force you to start over when you try to incorporate a new data source.
Your MDM project plan will be influenced by requirements, priorities, resource availability, time frame and the size of the problem. Most MDM projects include at least these phases:.
This step is usually a very revealing exercise. Some companies find they have dozens of databases containing customer data that the IT department did not know existed. This step involves pinpointing which applications produce the master data identified in the first step, and—generally more difficult to determine—which applications use the master data.
Depending on the approach you use for maintaining the master data, this step might not be necessary. For example, if all changes are detected and handled at the database level, it probably does not matter where the changes come from. For all the sources identified in step one, what are the entities and attributes of the data and what do they mean?
This should include:. If you have a repository loaded with all your metadata, this step is an easy one. If you have to start from database tables and source code, this could be a significant effort.
These should be the people with the knowledge of the current source data and the ability to determine how to transform the source data into the master data format. In general, stewards should be appointed by the owners of each master data source, the architects responsible for the MDM softwares and representatives from the business users of the master data.
This group must have the knowledge and authority to make decisions on how the master data is maintained, what it contains, how long it is kept and how changes are authorized and audited.
Hundreds of decisions must be made in the course of a master data project, and if there is not a well-defined decision-making body and process, the project can fail because politics prevent effective decision-making.
Decide what the master records look like, including what attributes are included, what size and data type they are, what values are allowed and so forth. This step should also include the mapping between the master data model and the current data sources.
This is normally both the most important and most difficult step in the process. If you try to make everybody happy by including all the source attributes in the master entity, you often end up with master data that is too complex and cumbersome to be useful. For example: If you cannot decide whether weight should be in pounds or kilograms, one approach would be to include both WeightLb and WeightKg.
While this is a pretty trivial example, a bigger issue would be maintaining multiple part numbers for the same part. As in any committee effort, there will be fights and deals resulting in suboptimal decisions. You will need to buy or build tools to create the master lists by cleaning, transforming and merging the source data.
You will also need an infrastructure to use and maintain the master list. These functions are covered in detail later in this article. You can use a single toolset from a single vendor for all of these functions or you might want to take a best-of-breed approach. In general, the techniques to clean and merge data are different for different types of data, so there are not a lot of tools that span the whole range of master data.
Some tools will do both, but generally tools are better at one or the other. The toolset should also have support for finding and fixing data quality issues and maintaining versions and hierarchies. Versioning is a critical feature because understanding the history of a master data record is vital to maintaining its quality and accuracy over time. Looking at the big picture, functional capabilities for which to look include data modeling, integration, data matching, data quality, data stewardship, hierarchy management, workflow and data governance.
From a non-functional perspective, you should also consider scalability, availability and performance. Once you have clean, consistent master data, you will need to expose it to your applications and provide processes to manage and maintain it. When this infrastructure is implemented, you will have a number of applications that will depend on it being available, so reliability and scalability are important considerations to include in your design.
In most cases, you will have to implement significant parts of the infrastructure yourself because it will be designed to fit into your current infrastructure, platforms and applications. This step is where you use the tools you have developed or purchased to merge your source data into your master data list. This is often an iterative process that requires tinkering with rules and settings to get the matching right.
This process also requires a lot of manual inspection to ensure that the results are correct and meet the requirements established for the project. No tool will get the matching done correctly percent of the time, so you will have to weigh the consequences of false matches versus missed matches to determine how to configure the matching tools. False matches can lead to customer dissatisfaction if bills are inaccurate or the wrong person is arrested.
