What is scrum methodology? What it's used for and what is the best software tool for it?

It's a FrameWork for manging the process of Agile Methodology.

Scrum is an Agile framework for completing complex projects. Scrum originally was formalized for software development projects, but it works well for any complex, innovative scope of work. The possibilities are endless. The Scrum framework is deceptively simple.

• product owner creates a prioritized wish list called a product backlog.
• During sprint planning, the team pulls a small chunk from the top of that wish list, a sprint backlog, and decides how to implement those pieces.
• The team has a certain amount of time — a sprint (usually two to four weeks) — to complete its work, but it meets each day to assess its progress (daily Scrum).
• Along the way, the ScrumMaster keeps the team focused on its goal.
• At the end of the sprint, the work should be potentially shippable: ready to hand to a customer, put on a store shelf, or show to a stakeholder.
• The sprint ends with a sprint review and retrospective.
• As the next sprint begins, the team chooses another chunk of the product backlog and begins working again.

Scrum is an agile project management methodology or framework used primarily for software development projects with the goal of delivering new software capability every 2-4 weeks. It is one of the approaches that influenced the Agile Manifesto, which articulates a set of values and principles to guide decisions on how to develop higher-quality software faster. ActiveCollab is a great, affordable solution for small businesses. Because it’s so easy to use, project managers don’t need to stress about teaching their team how to use this celebrated software. Its powerful document management, email-based communication features, priority and task control, and budgeting features have made it particularly attractive for project managers trying to manage multiple projects. Pros: Intuitive, outstanding support, iOS apps, can bill the client straight through the app, and the ability to limit which user sees what. Cons: Timeline and column views for tasks instead of Gantt or Kanban boards. Cost: Self-hosted at $499; $49/month for up to 15 team members.

The Scrum approach to agile software development marks a dramatic departure from waterfall management. Scrum and other agile methods were inspired by its shortcomings. Scrum emphasizes collaboration, functioning software, team self management, and the flexibility to adapt to emerging business realities.

Scrum is a methodology used mainly in Software Development Management especially when the development unit works as one unit to reach one common goal. Have you ever worked in the software business and found that your customer is changing mind so often? Scrum will help you out managing these changes flowlessly.

We are using a free open source application for that called "OrangeScrum". It's powerful, very helpful and easy to use. Give it a try :)
