How to Position Your Team for Success in Estimation

Estimates are critical if you want to be successful with projects. If you begin with a bad estimating approach, the project will almost certainly fail. To produce a much more promising estimate, direct each estimation-process issue toward a repeatable standard process. A smart approach reduces the degree of uncertainty. When dealing with presales phases, having the most precise estimation findings can assist you to deal with the project plan. This also helps the process to function more successfully, especially when faced with tight schedules and the danger of deviation.

Why Agile Teams Have to Understand How to Analyze and Make adjustments

How do we acquire knowledge? This is one of the seemingly basic but critical questions you and your team members must ask and consider. We are experts; therefore, we understand why we study and what we should learn. However, many of us do not give enough thought to how we learn.

A Complete Guide To CSS Houdini

As a developer, checking the cross browser compatibility of your CSS properties is of utmost importance when building your website. I have often found myself excited to use a CSS feature only to discover that it’s still not supported on all browsers. Even if it is supported, the feature might be experimental and not work consistently across all browsers. Ask any front-end developer about using a CSS feature whose support is still in the experimental phase in most prominent web browsers. ????
