Those who utilise the built in Native mode Reporting Services Report Manager will find it looks quite bland. The good news is with a little Cake Decorating 101, the Report Manager can be given a new lease on life, and easier on the corporate eyes.
Before getting the hands dirty, you will need to workshop the requirements for look and feel. This will include, colours (at least a primary corporate colour, but an optional secondary), fonts, corporate logo (sized to 48 x 48 pixels) and site title (something more personal instead of the default title “SQL Server Reporting Services”).
