Suggestion for Business Improvement?

Its always better that you take suggestions from everyone and do what you feel is right.
This not only opens door for new solutions but also enhance unity!

One interesting idea I've seen implemented somewhere was these "Break rank meetings" where a senior manager would regularly (maybe monthly) meet up with junior or mid-level employees from different departments for breakfast/coffee etc. and just discuss freely various topics. It was informal, some social conversation so everyone can feel comfortable, round the table introductions and then open discussions about what can be done better - all with a positive, constructive attitude.
I found them to work really well, but they do require commitment from senior management for that to happen regularly, as they're the ones driving it. But the feedback can be really good and it has also the benefit of acting like a team building exercise, breaking down barriers between departments, and so on.

Of course you call a meeting. Or you keep a suggestion box (and take it seriously). Or you ask group or department heads to feedback from their team and then report it to the head. But definitely has to be amongst a group of people. What should and shouldn't be implemented must properly be decide by the management then, keeping everyone's views in mind.
