How do you learn to give deadlines for a project?

Question

Project management

I've been working as a coder for about a year now. But I never learned to give deadlines for projects from scratch. I give an approximate time, but I don’t even know how to evaluate. Of course, I take into account the same taba carousels, and similar elements.
Well, if you take it objectively, how to determine how much I can allow to typeset certain blocks.
Thanks for your help, any information would be appreciated.

Answer 1

In general, this skill comes with experience, figure out the deadlines, work, see how you met or did not meet, analyze what went wrong, how to change further estimates. Do not forget to include all kinds of risks, technical and not only, in the assessment.

Answer 2

You're guessing.
And you multiply by 2. This will be the real time.

Answer 3

This garbage also infuriates me, I could not evaluate projects in any way. Then I decided to do so, took the project, talked for a while, and then, stupidly, timed how much time I spent working, dividing it into parts. I divided the work into pages: catalog, shopping cart, product details, news, reviews, about the company, contacts, etc. - I'm talking about pages. Then I took 1 more project, then 1 more. I analyzed where and how and for how much I did. I made an estimate with time for myself, where I took into account all the possible sections of the sites and the pages that they usually draw and want on most sites, be it shops or business cards. Further, I take the time that I am ready to spend in a day, let's say 3-4 hours, divide by the total time, let's say it turned out to be a week. At the end, I boldly say to the client, a week and a half)))) I do this now

Answer 4

Divide the task into parts until you can say exactly how long it will take you to complete each of the small parts. First up to the absurd: write a paragraph of text - 2 minutes, make a general page layout - 1 hour, add a carousel - 15 minutes, etc. Then adapt and be able to adequately evaluate labor costs.
The most important thing is not to give the numbers to the customer right away. Well, like - "oh, the task is garbage, I'll do it in a couple of hours." Better tell me - I need a couple of hours to estimate the labor costs, I will contact you.

Answer 5

The terms depend purely on the person, on his skills, his experience, his self-organization.
Everyone must learn to determine how fast he works.
Many beginners do not have enough experience or self-organization, so write down your work and the time spent, analyze.

Answer 6

1. When planning, we imagine a straight line from point A to point B. In fact, it will be an arc. Therefore, we need to multiply the term we propose by Pi, since the circumference is calculated using the formula Pi x diameter.
2. Plan not only work, but also testing.
3. If the term is in days, add a day, in weeks - a week, in months - a month. Usually this time is always not enough to polish the result.
4. Ask the customer if your predecessor met the deadline?
Yes - he is a genius, refer to him.
No - I will name the real terms in which I will meet, but they may seem exaggerated to you.
5. Turn in work before the deadline you set and ask to mention it in the review.

Answer 7

The universal rule is to calculate how much you need and multiply by Pi.
In your case, you need to multiply by 2. It will be more or less close to the truth.
