We take mental shortcuts every day in order to save our energy while achieving satisfactory results. These shortcuts, or heuristics, are in fact so mentally economical, that we are mostly not even aware of them! Yet, we use them all the time. In this episode, we talk with Rebecca Wirfs-Brock about heuristics we use in software design and why is it important to be aware of them. Rebecca is an object oriented design pioneer and an inventor of responsibility driven object design. She currently serves as a director of the Agile Alliance Experience Report Initiative and as a president of the Wirfs-Brock Associates consulting firm.
