When an IT System is designed, at the stage of
                requirements engineering, during requirements
                prioritizing, one of the prioritization criteria is importance. For instance, Single-Criterion
                Classification -
                one of the techniques for Requirements Prioritization is based on the requirements classification
                according to the
                importance of the realization of the requirement for the success of the designed and developed system.
                The most
                important are the ones that are assigned to the Mandatory class. It’s a set of requirements that must be
                implemented. They are really important.
With reference to other area, photography area, when it
                comes to
                composition, in any photo, an interesting and good composition starts with a good subject that inspires
                the
                photographer. Once it has been chosen, we can and we probably should eliminate all distractions that
                disturb the
                viewer from focusing on the center of interest. What is more, as a task or an aim of the photographer we
                can adopt
                finding order amid chaos and deciding what is important for him.
It tends to mean that this
                feature, this
                attribute, this criteria - importance needs to be founded and identified. And in contrast to the fact
                that it
                sounds natural and obvious, it’s sometimes becoming increasingly clear that there is a necessity to
                ’take the bull
                by the horns’. In the name of facing an importance. And that’s sometimes a challenge, a hard thing to
                do.
