Higher productivity may come at the cost of increased numbers of software bugs

​If the productivity is only measured by the time it takes to write code, then it may influence people who write that code to be sloppy in order to meet the deadlines.

Not only deadlines need to be considered in such a case, but it is necessary to account for complexity of code.

If code is simple, then it is possible to provide estimates, but if the code is complex, then it is difficult to provide any estimates.

Long estimates may be questioned by the mangers, short duration estimates may put people who write that code to be in the uncomfortable position.

They either going to be working long hours in order to meet the timeline that was given, or they going to write sloppy code, this will result in more software bugs and stress to that person that is writing that code.

If the task is difficult to estimate, and it very complex, then consider splitting this task into several smaller tasks.

By doing so, it will be easier to estimate duration of the main task, and it will reduce the stress of the employees.

Even so errors maybe helpful to development team or to QA team, errors need to be suppressed in production environment for viewing by everyone. Errors are good way to troubleshoot an issue therefore only trusted people can have access to this information. If not a trusted person get an access to this information, this information maybe used against the company and for a personal benefit. What to do in a case when there are more servers than one? Even so it is possible to inspect the log files in a single server, however it is impossible to do so when there is more than one server is available and web traffic is redirected to a different server each time. Log aggregation is needed in this case. All of the logs will be send to a central location. Logs may contain sensitive information. Please consult your company lawyer of how long logs can be stored, because logs can be use...
