Add Less An Article by Cassidy Williams css-tricks.com A few people have asked me what I did to make this [website] so fast. The answer is: nothing. I just didn't add anything to make it slow. I kept it simple. The pages are pre-rendered. The CSS is inlined. I didn't add unnecessary javascript. The work was done before you got there. Your websites start fast until you add too much to make them slow. Do you need any framework at all? Could you do what you want natively in the browser? Would doing it without a framework at all make your site lighter, or actually heavier in the long run as you create or optimize what others have already done? performanceminimalism
Feature parity An Article martinfowler.com Whilst Feature Parity often sounds like a reasonable proposition, we have learnt the hard way that people greatly underestimate the effort required, and thus misjudge the choice between this and the other alternatives. For example even just defining the 'as is' scope can be a huge effort, especially for legacy systems that have become core to the business. Most legacy systems have 'bloated' over time, with many features unused by users (50% according to a 2014 Standish Group report) as new features have been added without the old ones being removed. Workarounds for past bugs and limitations have become 'must have' requirements for current business processes, with the way users work defined as much by the limitations of legacy as anything else. Rebuilding these features is not only waste it also represents a missed opportunity to build what is actually needed today. These systems were often defined 10 or 20 years ago within the constraints of previous generations of technology, it very rarely makes sense to replicate them 'as is'. softwarefeaturesrepair
