**Update 10/12: I’m now acknowledged as a CDMP Associate after passing the Fundamentals Exam. Questions for me? Drop them within the feedback or be part of the examine group.**

**Update 8/15: it’s not too long ago come to my consideration that the certification exams are open e-book, which is extraordinarily thrilling as a result of it means much less time memorizing and extra time working with information in an actual world setting. Also, I’m beginning a examine group on Facebook — be part of for assist together with your examination prep.**

Eight years in the past, information science was proclaimed “the sexiest job of the 21st century.” Yet plodding by hours of information munging nonetheless feels decidedly unsexy. If something, the storied rise of the data science profession has illustrated simply how poorly most organizations are doing in terms of managing their information.

Enter the Certified Data Management Professional (CDMP) from Data Management Association International (DAMA). The CDMP is the most effective information technique certification you’ve by no means heard of. (And truthfully, when you think about the truth that you’re in all probability working a job that didn’t exist ten years in the past, it’s not shocking that this certification isn’t widespread simply but.)

Data technique is an important self-discipline that spans end-to-end administration of the info lifecycle in addition to related points of information governance and key issues of information ethics.

This article outlines the hows and whys of getting the CDMP, which lays the groundwork for efficient thought management on information technique. It additionally features a survey — you may provide your ideas on crucial points of information administration for data science and take a look at the consensus of the neighborhood.

I’m together with an affiliate hyperlink to the DMBOK on Amazon, the reference information that’s required for the examination, on condition that it’s an open e-book check.

About the CDMP Exam

 
Training for the CDMP confers experience throughout 14 areas associated to information technique (which I’ll cowl in additional element in a later part). The check is open e-book, however the 100 questions on the examination should be accomplished inside 90 minutes — not numerous time to be trying issues up.

The format of the examination is a number of selection — select the only appropriate possibility out of 5. You can mark questions and are available again to them. At the conclusion of check taking, you get instant suggestions in your rating.

Anything over 60% is taken into account passing. This is simply wonderful in the event you’re involved in getting your CDMP Associate certification and shifting alongside. If you’re within the superior tiers of CDMP certification, you’ll should move with a 70% (CDMP Practitioner) or 80% (CDMP Master). To get licensed on the highest stage, CDMP Fellow, you’ll want to achieve the Master Certification and in addition display business expertise and contribution to the sector. Each of those superior certifications additionally require passing two Specialist exams.

This brings me to my remaining level, which is about why — purely from a profession development standpoint — you must selected to place your self by the finding out and examination taking course of for CDMP: certification from DAMA is related to high-end positions in management, administration, and information structure. (Think of CDMP as getting credentialed right into a semi-secret society of information ninjas.) Increasingly, enterprise roles and federal contracts associated to information administration are requesting CDMP certification. Read extra.

  • Four tiers for various ranges of information administration professionals
  • 60% rating requirement to move lowest stage of certification
  • Associated with elite roles
  • Provides three yr membership to DAMA International
  • $311 examination charge is cheaper than different data-related certifications from Microsoft and The Open Group

Cons:

  • DAMA will not be backed by a serious tech firm (e.g. Amazon, Google, Microsoft) that’s actively pushing advertising and marketing efforts and driving model recognition for CDMP certification — which means CDMP is more likely to be acknowledged as useful primarily amongst people who’re already conversant in information administration
  • $311 examination charge is comparatively costly in comparison with AWS Cloud Practitioner cert ($100) or GPC certs ($200)

Alternatives:

Why data scientists ought to get CDMP licensed

 
Still not satisfied why information technique is vital? Let’s have a look from the attitude of a data scientist aiming to extend their data and incomes potential.

It’s been mentioned {that a} data scientist sits on the nexus of statistics, laptop science, and area data. Why would you need to add yet another factor to your plate?

Successwise, you’re higher off being good at two complementary abilities than being wonderful at one

Scott Adams, creator and creator of the Dilbert comics, presents the thought that “every skill you acquire doubles your odds of success.” He acknowledges this can be considerably of an oversimplification — “obviously some skills are more valuable than others, and the twelfth skill you acquire might have less value than each of the first eleven” — however the level is that generally it’s higher to go extensive than to go deep.

Setting apart the relative magnitude of the profit (as a result of I critically doubt it’s 2x per ability… thanks, regulation of diminishing marginal returns), it appears unquestionable that broadening your skillset can result in extra vital good points relative to toiling away at studying one particular abilities. In a nutshell, because of this I feel it’s vital for a data scientist to study information technique.

Generally talking, having range in your skillset lets you:

  1. Problem resolve extra successfully by drawing on cross-disciplinary learnings
  2. Communicate higher together with your teammates from different specialties
  3. Get your foot within the door when it comes to having access to new tasks

Understanding information technique transforms you from being a knowledge shopper into an empowered information advocate at your group. It’s price placing up with all of the tongue tornado acronyms (DMBOK — actually? Couldn’t they’ve simply referred to as it The Data Management Book?) so as to deepen your appreciation for the end-to-end data producing course of.
