Deep working

My boss constantly remind his team that we should do more of deep work rather than shallow working in our day job. Being responsible for opertions, I find it quite challenging to focus more on deep work as every time I try to get on with doing more of strategic work, invariably I'm dragged into deal with fixing day to day stuff and fire fighting. Not to say some of the issues coming along my way isn't important as they are directly have an impact to customer service and satisfaction; but the more I get those leave me with little time to get on with more important strategic stuff.
I've lately been feeling kind of frustrated about this. So last week I thought I must try and spend less time myself in any shallow work come in my way and delegate them to limited number in my team as much as possible. This new self discipline helped me to spend more time in planning for a couple of strategic initiatives, that would bring change in the operations and even cost benefits. I also managed to successfully organise and facilitate a couple of meetings among stakeholders from other business areas whom I need agreement and support to initiate those initiatives.
I have to say looking back at the last week in the day job, I'm very happy and satisfied of the productivity I achieved
