Adaptive software development and scrum both come under the overall heading of agile software development, but are two different beasts with differences between them. These are two different approaches with the same aim i.e., agile development. Below, we will write more on what differentiates the two.
It is necessary to know the differences between these two approaches since Scrum, as a part of agile software development is already a very famous methodology, whereas the adaptive software development is relatively new, but also a strong upcoming methodology ready to take the software development market by storm. Agile methods are always preferred over traditional development approaches to incorporate major factors such as increased levels of customer participation and satisfaction, project delivery flexibility, and acceptance of ongoing requirements or design changes at any level in the development process. This is the usual development scenario and that is why agile development methods are used mostly. Most commonly used agile methods include:
- Adaptive software development
- Scrum
- Feature driven development
- Extreme programming
Even though all these strategies aim at the same set of objectives (well almost), they do take somewhat different paths (having some items common, and yet others are different). It is important to know the differences between them. Otherwise how you are going to maintain agility in your development structure? Comparison between different agile methodologies, their common points and differences lets the managers choose the most appropriate agile method for their software characteristics.
There are many traditional techniques for drawing comparisons between 2 software development techniques. In this post, Scrum and ADS have been compared on basis of 2 areas, namely software construction and software requirements.
First difference between adaptive software development and the scrum approach is that in the former, there is no predefined technique to be followed. In scrum there are certain predefined techniques to be followed. On the other hand the focus of adaptive software development is on the end result rather on the steps. Adaptive software development methodology implements a particular technique only if it is required.
Since the last two years agile principles have encompassed methods such as extreme programming, feature driven development, adaptive software development and so on. So far companies using scrum or adaptive software development have been able to deliver successful products. Scrum is described as a process for management and control used for cutting down the complexity. This is used by the organizations who want to deliver products faster. This approach to software development has been used on advanced development methods including software; it usually works well in the object – oriented development environment.
On the other hand adaptive software development is described as methodology for developing reliable and re – adaptive software. It is used by the organizations who want their products to function in a wide range of changing conditions. Software built with this approach are capable of reconfiguring themselves to better suit to the environment. It can be used under any kind of environment. Any technique can be applied here to make software as much flexible as possible. The owners are responsible for estimating backlog items in scrum. In adaptive software development it is mainly the task of the developers.
Scrum follows time-boxing method for speedy delivery. At the start of each timebox, a sprint planning meeting is held. A backlog that can be achieved is picked up by the team members and they decide how it can be achieved.
Scrum may have 1 to 4 teams with 5 – 9 members and adaptive software development may have even more number of teams dedicated to each phase of development process. Agile developers play a number of roles – analysing, estimating, designing, coding and testing. Even though the typing burden is less, there is a lot of stress because of the short frames. But you get to see your progress through user reviews and daily meetings.
