Gartner four V’s model –volume, velocity, veracity, variety
According to Gartner, Big Data can be described using the ‘3Vs’:
Volume – this refers to the significant amount of data that the organisation needs to store and process. Match.com (an online dating company) estimates that it has 70 terabytes of data about its customers. (Hajmi)
Variety – big data can come from numerous sources. For example, Match.com (with user permission) also gathers data on users’ browser and search histories, viewing habits and purchase histories to build an accurate view of the sort of person the customer might like to date. (xilma xilligi)
Velocity – data is likely to change on a regular basis and needs to be continually updated. For Match.com, new customers will join the service, or existing customers will find their needs and wants from a partner may change. Match.com needs to continually gather data to ensure that they are able to deal with this. (tezligi)
Another V which is sometimes added by organisations to the above list is:
Veracity (truthfulness) – it is vital that the organisation gathers data that is accurate. Failure to do so will make analysis meaningless. Match.com has found that when gathering customer data, customers may lie to present themselves in the most positive light possible to prospective partners. This will lead to inaccurate matches. Using non-biased sources of information (such as purchasing or web browser histories) rather than relying on customer feedback is therefore important. (ishonchligi)
Element mentoring process
Mentoring is the process where one person offers help, guidance, advice and support to facilitate the learning and development of another. A mentor is usually (although not always) a skilled, senior member of staff who:
offers practical advice and support
can give technical, ethical and general guidance
can help with the development of interpersonal and work skills
is an impartial sounding board
is a role model who can help the mentee (the individual being mentored) to improve their career goals.
