This impact is said to be the severity of a bug: the impact a bug causes when encountered by users. Thus, severity, as a software metric does have a very precise meaning. Unfortunately, severity levels are not standardized in industry and are decided by each software producer, if they are even used.n 2002, a study commissioned by the US Department of Commerce ' National Institute of Standards and Technology concluded that software bugs, or errors, are so prevalent and so detrimental that they cost the US economy an estimated $59 billion annually, or about 0.6 percent of the gross domestic product.
1 Caterers often charge a setup cost of $30 to $200 per bartender working the event. 2  Sometimes this amount is included in the per-guest fee. 3  Many caterers require you to pay an hourly fee for the bartender, around $25.
The cost of a bartender will depend on how many people are going to be attending the party, the date of the event, geographical location and individual/company you choose. Most personal bartenders will want to serve 50-75 guests at a maximum, so for every 75 guests, you will want to factor an additional bartender. On average, expect to pay anywhere from $15 to $50+ per hour. Most will require you book in four-hour increments. These rates can be 30 to 50 percent more if planned on a holiday.
