Modern software development approaches have evolved as fast as they’ve produced products. Dozens of practices and processes currently exist, not to mention each individual team’s unique components.
Still, two of the most common and all-encompassing methodologies are the agile and waterfall approaches to development. While they contain many of the same components, the two approaches are vastly different.
Project management software tools are a key component to keeping teams on track. These tools often vary in their featuresets, some favoring long-term, waterfall planning, while others are geared towards the fast-paced agile approach.
Agile project management is based on rapid iteration and user testing. While traditional methodologies focus on long-term goals and outlining requirements up front, agile teams take a choose-your-own-adventure’ approach. After constantly testing, pitching ideas and hearing from users, agile software development aim to mold final products around users’ needs by learning what the products are as they go along. Popular products: JIRA, Targetprocess, Telerik TeamPulse and Pivotal Tracker.
- Embraces ideas — Ideas are being tossed around at all points in the development process. Some may be rejected, but nearly all will be tested.
- Users are heard — Developers can get a clearer idea of the customers’ needs through multiple sessions of user testing and feedback.
- Tough to track — With components of the project constantly changing, teams may have difficulties tracking changes, phases and schedules.
- Tougher to plan — Teams may come into the process with a general idea for a completion date, but they often alter schedules multiple times as goals are added or abandoned.
Here is the traditional, safe approach to software development. Team members and managers outline all requirements up front. From there, strict schedules are closely monitored. Before teams move to a new phase of the sequential development schedule, requirements must be met and tasks must be completed. Instead of testing changes throughout the process, teams develop a near-complete product and push it to user testing at a specified date. Popular products: LiquidPlanner, Microsoft Project, Smartsheet and Basecamp.
- Simple and organized — One by one, tasks are checked off and team members know what to do next. New features are rarely be added, allowing developers to manage their schedules without interference.
- Clear timeline and goals — This often benefits larger teams rather than smaller ones, but managers know the date a project will begin, tasks will be advanced and the product will be completed.
- Rigid structure — As problems arise during the development process, it is difficult to accommodate new tasks while maintaining strict schedules, possibly resulting in decreased functionality.
- Longer process — It can be difficult and time consuming to compile all requirements prior to initial development. Also, if the project planner is assigning realistic deadlines, the process will likely be drawn out.
