binary predictions@next Perl environment

true binary predictions = predictions that can be clearly proved right or proved wrong, never ambiguous or "outcome unknown". Here are a few almost-binary predictions on the Perl systems in the next company. Let's verify them 3 months into the job.

BP: Adaptability -- to frequent change is one fo the biggest pains, if not the #1. Current Adaptability level isn't state of the art.

BP: Speed -- to market is likely to be the #1 metric. This depends on Adaptability.

BP: modularity, decoupling -- between modules is an absolute must for Adaptability and Speed. As a large dev team, they need modularity.

P: perl module dev -- Perl module is the standard solution to modular development in large teams. I'm expected to understand and use perl modules.

P: OO -- Expertise with OO perl modules, designs, best-practices ... is perhaps not insignificant to my role, my job performance, entire-team performance.
- > I believe OO can help Adaptability-to-change, Speed-to-market,

BP: creating Perl classes -- within first month, I am not expected to do so for production systems.

P: parsing -- biz rules are likely to change often. As far as parsing is concerned, Flexibility could be the #1 Speed factor, leading to fast and reliable implementations.

BP: data volume -- is a non-trivial challenge for the perl scripts. Perl Modules, best-practices, designs to solve this problem will receive their attention.

P: Untuned SQL -- but functional. Once found, they need remedy, and will not be ignored or accepted. Not a Binary Prediction, because some unimportant queries will definitely be accepted even if untuned.

P: test coverage -- many existing non-trivial perl scripts will not have reliable test coverage written for them, but not sure if reliable test coverage is feasible

P: readability -- is a non-trivial headache, even if long-tolerated, but not sure how much improvement is feasible.

BP: DB access -- in this environment is a standardized and optimized routine that i don't need to try and improve.

BP: basic XML API -- in this place is a standardized and optimized routine that I need not try and improve. You may be able to put XML to new usage, though. You may innovate on a higher level.
