As a manager of IT services, it can be a huge pain to actually take all of the process-driven knowledge you've learned in to practical use. One of the guides we here at SSI Logic find to be invaluable, is the Measuring ITIL handbook, available at Amazon.
One of the greatest things about this guide is that it cuts through the clutter of theory and concepts, and offers the KPIs, CSFs, and other measurements you need to do your job. Use those ITIL calculations to create dashboards, reports, and tracking mechanisms. Its funny that this book is know 10+ years old, but still relevant as ever.
You also might want to check out our own ITIL book on Amazon which as a greater focus on ITIL exam prep- but valuable all the same ;)
