Empathize Not Sympathize

Many enterprise software vendors sympathize. "We know it's a bad experience" or "We will fix the usability." One of the reasons the software is not usable is because the makers never had any empathy for the end users who would use it. In many cases the makers didn't even know who their end users were; they only knew who would buy the software. As far as enterprise software is concerned people who write checks don't use the software and people who use software don't write checks and have a little or no influence in what gets bought. Though the dynamics are now changing. Usability is the last step; it's about making software usable for the tasks that it is designed for. It's not useful at all when the software is designed to solve a wrong problem. Perfectly usable software could be completely useless. It's the job of a product manager, designer, and a developer to assess the end user needs—have empathy for them—and then design software that...

Over a period of time, the RDBMS grew in functions and features such as binary storage, faster access, clusters, sophisticated access control etc. and the applications reaped these benefits. The traditional RDBMS became a non-fit for cloud-scale applications that fundamentally required scale at whole different level. Traditional RDBMS could not support this scale and even if they could it became prohibitively expensive for the developers to use it. Traditional RDBMS also became too restrictive due to their strict upfront schema requirements that are not suitable for modern large scale consumer web and mobile applications. Due to these two primary reasons and a lot more other rea...
