I'd say it depends on the "rut" which is vague.

Are you doing agile software development?

Give everyone on the team a chance to provide input and make suggestions. Everyone has input. It may be good, bad or just a moot point but giving people the chance to give input is a great start.

Is it all work and no play? Team building events outside work are always good for the team. Shows appreciation and gets everyone out of the work work work mentality...

Is the pay and benefits worth it for what people are doing?
