Comme le montre une nouvelle \u00e9tude de Xerox, une grande majorit\u00e9 s'attend \u00e0 ce que les connaissances tir\u00e9es des Big Data aient un impact positif sur leur retour sur investissement (ROI) dans les douze mois suivant leur mise en \u0153uvre.<\/p>\n
Plus de la moiti\u00e9 des entreprises participantes (56 %) ont d\u00e9j\u00e0 enregistr\u00e9 des avantages commerciaux gr\u00e2ce au Big Data. Au nom de Xerox, Forrester Consulting a men\u00e9 une enqu\u00eate aupr\u00e8s de 330 dirigeants d'entreprise de haut niveau dans cinq pays d'Europe occidentale.<\/p>\n
Cette \u00e9tude a r\u00e9v\u00e9l\u00e9 que la mauvaise qualit\u00e9 des donn\u00e9es et le manque de comp\u00e9tences en mati\u00e8re de traitement des donn\u00e9es sont les principaux obstacles \u00e0 une \u00e9ventuelle transformation de l'entreprise \u00e0 l'aide de donn\u00e9es volumineuses.<\/p>\n
\"Les dirigeants d'entreprise comprennent que l'enracinement des connaissances bas\u00e9es sur les donn\u00e9es repr\u00e9sente un potentiel \u00e9norme pour l'entreprise, mais le terrain est encore assez difficile\".<\/em><\/p>\n d\u00e9clare Craig Saunders, directeur du centre de ressources analytiques de Xerox Consulting and Analytics Services.<\/p>\n Le big data est la cl\u00e9 de nombreuses d\u00e9cisions en 2015 : trois cinqui\u00e8mes (61%) des entreprises interrog\u00e9es affirment que les d\u00e9cisions qui seront prises au cours de l'ann\u00e9e \u00e0 venir seront davantage bas\u00e9es sur des connaissances aliment\u00e9es par des donn\u00e9es que sur des facteurs tels que l'instinct, l'opinion et l'exp\u00e9rience.<\/p>\n Des donn\u00e9es impr\u00e9cises peuvent co\u00fbter cher : 70 % des organisations sont encore confront\u00e9es \u00e0 des ensembles de donn\u00e9es impr\u00e9cis dans leurs syst\u00e8mes. 46 % estiment que ces ensembles de donn\u00e9es, parfois inutilisables, ont un impact n\u00e9gatif sur leur activit\u00e9 et qu'ils doivent \u00eatre r\u00e9vis\u00e9s de toute urgence.<\/p>\n S\u00e9curit\u00e9 et protection des donn\u00e9es : 37% des personnes interrog\u00e9es ont indiqu\u00e9 que la s\u00e9curit\u00e9 et la protection des donn\u00e9es faisaient partie des principaux d\u00e9fis lors de la mise en \u0153uvre de strat\u00e9gies de Big Data.<\/p>","protected":false},"excerpt":{"rendered":" Le Big Data peut repr\u00e9senter un avantage \u00e9conomique pour 74 % des entreprises
