One of the most important tasks of a software developer is not just writing code fast; it is the ability to find what causes errors and bugs whenever you encounter one and the ability to solve them quickly.
In 2007, Steve Jobs launched the first iPhone, which revolutionized the world. But because of that, many businesses dealt with the problem of changing the layout of websites from desktop to mobile by delivering completely different mobile-compatible websites under the subdomain of ‘m’ (e.g., https://m.facebook.com). And we were all trying to figure out how to work in this new world of contending with mobile and desktop screen sizes.
One of the most important skills for leaders to have is the ability to prioritize. To understand how we can organize all of the tasks that must be completed in order to complete a project, we must first understand the business we are in, particularly the project goals. There might be several project drivers that stimulate project execution and motivate a company to allocate the appropriate funding.
The best agile teams are built from people who work together as one unit, where each team member has both the technical and the personal skills to allow the team to become self-organized, cross-functional, and self-motivated. These are all big words that I hear in almost every agile project. Still, the criteria to make a fantastic agile team are practically impossible to achieve without one major factor: motivation towards a common goal.
Collecting and examining data from multiple sources can be a tedious process. The digital world is constantly evolving. To stay competitive in this fast-paced environment, businesses must frequently test their products and services. While it’s easy to collect raw data from multiple sources, it’s far more complex to interpret it properly.
