In pathology and anatomy the penumbra is the area surrounding an ischemic event such as thrombotic or embolic stroke. Immediately following the event, blood flow and therefore oxygen transport is reduced locally, leading to hypoxia of the cells near the location of the original insult. This can lead to hypoxic cell death and amplify the original damage from the ischemia; however, the penumbra area may remain viable for several hours after an ischemic event due to the collateral arteries that supply the penumbral zone.
As time elapses after the onset of stroke, the extent of the penumbra tends to decrease; therefore, in the emergency department a major concern is to protect the penumbra by increasing oxygen transport and delivery to cells in the danger zone, thereby limiting cell death. The existence of a penumbra implies that salvage of the cells is possible. There is a high correlation between the extent of spontaneous neurological recovery and the volume of penumbra that escapes infarction; therefore, saving the penumbra should improve the clinical outcome.
NPS is a customer loyalty metric that measures customers’ willingness to not only return for another purchase or service but also make a recommendation to their family, friends or colleagues.
It is a powerful and effective technique, which can greatly increase a company's revenue if used properly.
The main advantages of NPS are close correlation with a company's growth and easy collection, interpretation and communication of the data.
Net Promoter Score is a number from -100 from 100.
Scores higher than 0 are typically considered to be good and scores above 50 are considered to be excellent.
The industry average for Health Care / Medical / Dental Instruments is 0.
The final Net Promoter Score of a company strongly depends on a context in which the satisfaction is measured.
Consider an example: If Penumbra, Inc. sends out NPS surveys immediately after purchase, they are tracking their customers' initial excitement and the checkout experience.
On the other hand, if they survey their customers a few weeks after the purchase they are also tracking how satisfied their customers are with their products and services over time.
Therefore, comparing the NPS score of Penumbra, Inc. with your own without any further context is not that useful.
What is extremely useful though, is using the NPS methodology to track the satisfaction of your customers over time. That's where Customer.guru comes in.
