H3PO4(s) H2O(l) H3O (aq) H2PO4(aq) Ka1= 7.11×103

When we understand what management and performance evaluation is, some benefits of this process come to mind, such as improved results and satisfaction. Although, by themselves, these advantages are already quite expressive, the application of performance evaluation can also bring other developments. Understand 5 benefits of performance appraisal:

1. Provide knowledge
One of the main benefits of performance appraisal is the knowledge it provides for employees themselves. People need feedback on their activities, to know what to maintain and what needs to be changed.

This systematic measurement offers these data in an objective way and contributes to self-knowledge and work improvement. Similarly, the organization also knows its employees, potentials and limits better. Talents can be discovered and recognized.

If you are launching a service on the Internet, there is always the temptation to offer a free plan to entice the public.

You think people will like it - and want to upgrade to a normal plan with full features. This is a big mistake. If a person is completely satisfied with the free tariff, then he will stay on it forever !

And it will demand from you reliable service, new functions and make claims. The less the user pays, the more noise he makes on social networks and the more support he requires. Negative reviews come from free users, not from paid ones (this is quite logical if you think about it).

PM - Project manager (project manager).

You say that only 5 kettle will boil. PM insists that the client is asking very much and this is extremely important to us, you bend under the onslaught and decide to think about something. You throw a bag into the kettle, fill it with water and wait for the water to turn brown. You clearly understand that you will have to remember to wash the kettle, because this will leave tea rings and possibly mold. You pour the resulting colored water for the client, the PM says with a happy face: well, you see, you can. And you think that you would not want to do that to you ... But circumstances demand. And as soon as you relax, the PM flies in and says: have you even tried this?

You realize that there is no taste for the campaign ... You try to justify yourself, but then the PM interrupts you and says: what does the taste have to do with it, it's not boiling water and you quickly start thinking what to do. You think about boiling for a long time and find a ready-made solution - an old boiler in the closet. You throw it into a mug, plug it into an outlet, it heats up, and the PM looks at you and says: hmm ... We can't leave such dependence on the cable ... And you understand that a good solution just needs to be finished, naively believing that you are went in the right direction. You find the battery, connect it, and everything works, even though even the PM realizes that something is wrong here. And then the intrigue arrives ... PM-but there is no hour, two ... You start to think that they are either discussing your dismissal, or PM-and lost somewhere, maybe he has already decided to finish. But then the PM flies in and without a drop of explanation says: the client is very satisfied, it is necessary to make pasta just as quickly. You are at a loss - they say, okay, it worked, you go and look at the kettle and think, what else can be done in it. But since it's Friday night, you think that you've had enough of such adventures and agree with the PM for Monday.

For about a week, an Arctic storm raged in the United States. Atypically cold temperatures and snowstorms have covered half the country, but the worst is in Texas. The southern state's power grid failed to cope with the load, leaving millions of people without water, electricity and heat. Why did it happen?

First, the conditions are truly extreme. There has not been such a winter for almost 10 years, and in some places absolute records of negative temperatures have been set. Usually in Texas in winter there is a plus or a weak minus, and here in some places frosts are up to -20. Accordingly, the infrastructure and people are not ready for this. On the icy roads, dozens of dead, about 12 million people are experiencing problems with a shortage of water (pipes freeze), up to 3 million households were left without electricity and heat, people were forced to evacuate from their homes or warm up and spend the night in cars.

And this is not just news, but a reflection of reality, which is even worse than it might seem. According to experts, problems in the semiconductor market will persist until the end of this year.

About ten days ago, when I started updating apps in the App Store on my Mac, I ran into a curious error.


The internet is filled with stories of people whose Google accounts were blocked for unexplained reasons, which caused them to lose all their data, including years of e-mails, so I was quite worried. But I had never heard of such cases with Apple services and would not have expected such behavior from a company as loyal to consumers as Apple, so I decided it was a glitch and decided to try it later.
