How Flexible Is Your Approach To Software Dev?
From fault-testing to flexibility, there are plenty of different ways to plan a software development project. Which will you choose?
A successful software development project needs to introduce structure and planning from the outset to ensure that all runs smoothly. Coming up with the right methodology to support your software project is dependent on the size of your team, your end goals and how much flexibility you’re looking for. Here are some of the most popular software development models for you to consider using.
Waterfall Model
One of the most traditional custom software development models is the Waterfall which follows a linear sequence. The stages of your project will fall from top to bottom and are fairly rigid with little scope to change direction as required. Substantial planning is carried out before beginning a waterfall project and the usual path to follow is: decide the scope of the project, analyse the requirements, then design, implement, test, deploy and maintain as necessary.
The Waterfall model is criticised for its lack of flexibility, but it is useful in determining the progress of your project.
Agile Methodology
The Agile model relies on collaboration to produce software quickly. By liaising with different departments and making use of customer feedback to support the success of the project, this allows teams using the Agile model to respond to change as needed and make fixes on the go without holding the project back.
Scrum
This is based on the Agile model, in that team members take centre stage over processes and tools. However, with the Scrum method, the software project is broken down into short ‘sprints’ that last from one to four weeks. During a sprint, the end goals of the project are broken down into much smaller goals, which are worked on tirelessly and showcased during demos at frequent meetings. This model is incremental by nature, but the constant collaboration that occurs during meetings allows developers to identify the need for small changes and make them as needed before the next sprint.
Extreme Programming
This model is also based on the popularity of the Agile framework with the aim being to produce exceptional software in a short space of time, whilst creating a high quality of life for team members. This is achieved by committing to the following values: Simplicity, Communication, Feedback, Respect and Courage.
Similar to the Scrum, this model makes use of short development sprints. Testing is carried out frequently and changes can be made quickly as required to ensure that the finished software is bug-free.
Kanban
This software project model does not rely on firm guidelines to produce the finished product. Instead, the tasks within the project are broken down into small tasks which are each assigned to an experienced member of the team and expected to be completed within a few days. These tasks are then put into three piles of ‘To Be Completed’, ‘In Progress’ or ‘Completed’ so that there is a clear overview of how the overall project is advancing.
When deciding which software model to work with, start by looking at the size, experience and values of your team members. You may find that one model allows you to get the best out of your team whilst another restricts their talents somewhat, so be flexible until you find an approach that works for you!
