WHT/082311 § IT
does knows data and infrastructure (only) § Business knows the intelligence to be applied to the data to derive value § Business knows how to discover data pa;erns (manual and automated) – Data ScienRsts § Business understands their seman+cs beVer § Business can perform data interroga+on in an experiment and associate rules of engagement early on for data usefulness § IT can create reusable reports of these experimental results. § Business can siX the data to curate the context § Big Data needs to be curated to be useful The bDWH concept brings Business and IT together to create added value IN WHAT DOES THE bDWH CONCEPT DIFFER © 2013 Harro M. Wiersma – 23 September 2013 – Swiss Big Data Usergroup Zürich
19.
WHT/082311 THE bDWH
PARADIGM CHANGE © 2013 Harro M. Wiersma – 23 September 2013 – Swiss Big Data Usergroup Zürich
20.
WHT/082311 THE COMPLETE
bDWH VALUE CHAIN 20 Collec+on – Structured, unstructured and semi-‐structured data from mulRple sources Inges+on – loading vast amounts of data onto a single data hub Discovery & Cleansing – understanding format and content; clean up and forma[ng Integra+on – linking, enRty extracRon, enRty resoluRon, indexing and data fusion Analysis – Intelligence, staRsRcs, predicRve and text analyRcs, machine learning Delivery – querying, visualizaRon, real Rme delivery on enterprise-‐class availability Collec+on Inges+on Discovery & Cleansing Integra+on Analysis Delivery © 2013 Harro M. Wiersma – 23 September 2013 – Swiss Big Data Usergroup Zürich
21.
WHT/082311 KEY SUCCES
FACTORS § Business needs to drive and execute the bDWH program § Data colloca+on and discovery is the most cri+cal step § Metadata is needed to process the data prior and post bDWH integraRon § Data quality can be processed by integraRng taxonomies § Data visualiza+on is needed to discover data § Metrics and metadata will be the bridge to integrate to the bDWH § Centralized infrastructure is needed to create a data-‐hub © 2013 Harro M.

22.
WHT/082311 § Bring
together exis+ng internal knowhow, combine it with external knowhow. don‘t silo your teams. § It‘s not about hardware, it‘s about the concept and way of thinking. § Reusable data, but which data is the ‚sole truth‘? § Who owns your data? do they really want to have transparency? § Are we allowed to use our data as we would like to? § Think of new and future business-‐concepts to be supported. FIRST STEPS © 2013 Harro M. Wiersma – 23 September 2013 – Swiss Big Data Usergroup Zürich
23.
WHT/082311 The challenge
facing the business today is the ability to influence the buyer decisions in a window of opportunity that does not last long. The analyRcs available at a personalizaRon level drives the buyer whether it is choosing a Doctor or buying a new laptop. To compete in this new era, businesses need to be driven by data and analyRcs, which are largely different from tradiRonal transacRons and campaigns! Both the “GeneraRon Z” and “Millennial GeneraRon” of buyers will not be swayed by tradiRonal engagement models of selling products and services! FROM TRANSACTIONAL TO BEHAVIOURAL © 2013 Harro M. Wiersma – 23 September 2013 – Swiss Big Data Usergroup Zürich
24.
WHT/082311 PREDICTIVE BUSINESS
INTELLIGENCE – DATA ANALYSIS § you know what you know – perfect, use it! § you know what you don‘t know – learn § you don‘t know what you know – invesRgate § you don‘t know what you don‘t know – find someone who does! © 2013 Harro M. Wiersma – 23 September 2013 – Swiss Big Data Usergroup Zürich
25.
WHT/082311 § Do
not try to implement without integraRon in your current landscape § Find a easy target, for example your data-‐archive § Collabora+on is key! Learn from other industries § Create cross-‐func+onal teams: IT – Analysts – Business § Champion business value: a ROI is there! § OrganizaRons that don’t leverage the big data that they have, risk losing ground to their compeRtors § Get on it, now! TAKE AWAYS © 2013 Harro M. Wiersma – 23 September 2013 – Swiss Big Data Usergroup Zürich
