If you are going to deploy a CMDB, it is not enough to sit down and start to map the<strong>services<\/strong> spontaneously: first, you have to stop and think about it a little bit. <\/p>\n\n<p class=\"wp-block-paragraph\">If you have an opportunity, I recommend that you take a look at a <strong>study by Gartner,<\/strong> <a href=\"https:\/\/www.gartner.com\/doc\/3841872\/-steps-improve-it-service\" target=\"_blank\" rel=\"noopener\">4 Steps to Improve IT Service View CMDB Data Quality<\/a> (G00341988) Without reinventing the wheel, this study reminds us of some obvious ideas that I would like to mention. <\/p>\n\n<h2 class=\"wp-block-heading\">Gartner study: Choose the attributes of the CMDB wisely<\/h2>\n\n<p class=\"wp-block-paragraph\"> El estudio comienza fuerte, tal que as\u00ed: \u00abInaccurate configuration item data in an IT service view CMDB can delay incident resolution and degrade change quality\u00ab. Or in other words: <a title=\"CMDB ITIL: Definition and automation of IT processes\" href=\"https:\/\/blog.proactivanet.com\/gestion-de-servicios-de-ti\/definicion-del-proceso-automatizacion-camino-hacia-la-cmdb\/\"><strong>modeling of the services in the CMDB<\/strong><\/a>, if done with bad data, would result in a degradation of the service quality or a slower <a title=\"Incident, software and Event Management in ITIL\" href=\"https:\/\/blog.proactivanet.com\/gestion-de-incidencias\/gestion-de-eventos\/\"><strong>resolution of incidents<\/strong><\/a>. And so, you couldn\u2019t get off to a worse start.<\/p>\n\n<p class=\"wp-block-paragraph\"> <strong>Gartner\u2019s analysts<\/strong> focused their study largely on the importance of a clear <strong>definition of the attributes<\/strong> to be managed for the CIs included within the scope of the <strong>CMDB<\/strong>. It is important to have a clear idea of the CIs, to have a clear idea of the services and of the interrelationships, but it is just as essential to consider:<\/p>\n\n<ul class=\"wp-block-list\"><li>What attributes will we need?<\/li><li>Why and for what purpose will we need these attributes?<\/li><li>Who will be in charge of maintaining them and what methods will be used?<\/li><li>Do we have the capacity to deal with this quantity of information?<\/li><\/ul>\n\n<p class=\"wp-block-paragraph\"> Obviously, an incorrect decision regarding attributes has negative effects: \u201cWhen inaccurate CI data is used, it increases the risk of self-inflicted outages to critical IT services when changes are made. It also slows down IT teams\". You can say it louder, but not clearer: bad data = more <strong>risks<\/strong>; bad data = <strong> slower equipment.<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\"> Luckily, Gartner\u2019s advice is very easy to understand: \u201cReduce the scope of configuration item data models by removing all attributes that do not either uniquely identify the configuration item or have a clearly defined use case\u201d, or, paraphrasing, any <strong>information attribute<\/strong> that does not have a clearly defined use must be eliminated. <\/p>\n\n<p class=\"wp-block-paragraph\">And I agree with it 100%!! <\/p>\n\n<p class=\"wp-block-paragraph\">I hope that you enjoy it, and farewell<\/p>\n\n<p class=\"wp-block-paragraph\"> Jandro Castro. <\/p>\n\n<p class=\"wp-block-paragraph\">PS: if you still have any doubts, don\u2019t hesitate to take a look at this other post from a few months ago <a title=\"Maintain the CMDB up to date\" href=\"https:\/\/blog.proactivanet.com\/itil\/la-cmdb-es-como-el-euribor\/\">the CMDB and the Euribor,<\/a>\", maybe talking about mortgages and the Euribor will help you overcome your doubts... <\/p>\n","protected":false},"excerpt":{"rendered":"<p>For me, this always has seemed to be a rather critical...  <\/p>\n<div class=\"read-more mt-4 text-blue text-xs\"><\/div>\n","protected":false},"author":7,"featured_media":15877,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1512,1475],"tags":[1480,1482],"class_list":["post-18351","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-itsm-software-en","category-itil-en","tag-cmdb-en","tag-itam-en"],"acf":{"is_icon":[]},"post_mailing_queue_ids":[],"_links":{"self":[{"href":"https:\/\/www.proactivanet.com\/en\/wp-json\/wp\/v2\/posts\/18351","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.proactivanet.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.proactivanet.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.proactivanet.com\/en\/wp-json\/wp\/v2\/users\/7"}],"replies":[{"embeddable":true,"href":"https:\/\/www.proactivanet.com\/en\/wp-json\/wp\/v2\/comments?post=18351"}],"version-history":[{"count":0,"href":"https:\/\/www.proactivanet.com\/en\/wp-json\/wp\/v2\/posts\/18351\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.proactivanet.com\/en\/wp-json\/wp\/v2\/media\/15877"}],"wp:attachment":[{"href":"https:\/\/www.proactivanet.com\/en\/wp-json\/wp\/v2\/media?parent=18351"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.proactivanet.com\/en\/wp-json\/wp\/v2\/categories?post=18351"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.proactivanet.com\/en\/wp-json\/wp\/v2\/tags?post=18351"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
