Business Intelligence Business intelligence(*) (BI)refers to skills, knowledge, technologies, applications, quality, risks, security issues and practices used to help a business to acquire a better understanding of market behavior and commercial context. For this purpose it undertakes the collection, integration, analysis, interpretation and presentation of business information. BI applications provide historical, current, and predictive views of business operations, most often using data already gathered into a Data Warehouse or a Data Mart. BI applications tackle sales, production, financial, and many other sources of business data to support better business decision-making. Thus one can also characterize a BI system as a Decision Support System (DSS). (*) http://en.wikipedia.org/wiki/Business_Intelligence

Ricerche Quantitative L’obiettivo è fornire un’accurata misurazione del fenomeno oggetto di ricerca, mediante la raccolta e l’analisi di dati quantitativi e/o dati qualitativi strutturati.

L’intervista presenta delle peculiarità: • Ha forma strutturata • Limitato numero di domande aperte/ molte domande a risposta chiusa • Modalità di contatto usate: - telefonica - personali - postali - web- based
Le ricerche di mercatofieldwork Questionario E’ il format con cui vengono raccolti dati qualitativi strutturati e/o dati quantitativi La costruzione del questionario avviene attraverso: • Disegno del suo schema concettuale • Redazione • Verifica Modalità omogenee di rilevazione dei dati: le domande devono essere uguali per tutti gli intervistati e non devono lasciare spazio ad interpretazione soggettiva
