Best scrum tool in the market
Whiteboards and stickies. Start with the basics and get the teams involved before you invest in tools. At this point, tools are detrimental. Learn the game before investing. Some things you should think about: 1. Who's your audience? 2. What value are you capturing? 3. What type of measurements do you want visible? 4. Who will actually be using the tool? Keep retrospecting with the team over a few months while working the stickies and the whiteboards and the team will define the requirements. Compare this will the foreseen business value from your stakeholders and you should be able to drive a decision. Lastly, don't buy something that has too many gadgets; that defeats the simplicity of agile.
