Defining Priorities

 ITIL says that Priority should be a product of the Impact/Urgency matrix. ISO/IEC20000 agrees with that in 8.1 Incident and service request management.

It is customary that Priority of issues has four to five levels. It is most commonly marked with the numbers 1-4 or 1-5, where "1" is the highest and "4/5" is the lowest priority. 

PRIORITY = IMPACT X URGENCY .  

Below is how the ITIL priority matrix looks like:


·         Impact - Is defined by the criticality of downtime is for the business. Usually measured by the number of users affected. For e.g.: If one or more application/ services are down.
·         Urgency - it is usually defined in SLA for the specific IT service. If more than one service is impacted, parameters for the higher urgency service will be taken into account.

  1. Gone are the days when a business laid down an annual sum to have its information listed in the Yellow Pages. These days it’s crucial for all businesses to instead prominently list themselves in online directories.AIR pros is a directory of service companies in your area with a geolocation system, automatic translation of the content.The site is optimized to facilitate the referencing of referenced companies.You can search for companies by department or city and look at their profile before contacting them.
