To a medium size bowl, add flour, baking soda, cinnamon and salt. Lightly whisk together and set aside.
In a large mixing bowl, add softened butter, brown sugar and granulated sugar. Beat with a mixer until creamy.
To the bowl with the butter and sugar mixture, add eggs and vanilla. Beat until light and fluffy.
To the butter and sugar mixture, add the flour mixture a little at a time and beat the ingredients on low (so that the flour doesn't fly out of the bowl).
To the bowl, add oats and dried cranberries. With a large sturdy spoon or spatula, mix in the oats and dried cranberries.
Using a tablespoon, drop the dough on to an ungreased cookie sheet.
Bake in a preheated oven for 8 minutes or until the cookies are light golden brown. For a softer cookie, remove from the oven when the middle of the cookie still looks slightly soft (about 7 minutes but the amount of time may vary depending on the oven).
Transfer the cookies to a wire rack and let cool before serving.

Notes
TIP:
Instead of adding the eggs directly in the mixing bowl, it's a good idea to add them to a small bowl first just in case one of them is bad or has a spot of red in the yolk area.
