2. Requirements Definition

[@robertrahardja]

Lecture recordings shall be clear to understand the words of the speaker, including any questions and answers. Thank you MIT. Love this stuff.

[@JayJay-ki4mi]

Thank you MIT for providing this. It's helping me immensely with software design requirements and specifications. I know beggars can't be choosers, but I really wish the audio was clear. It feels like my ears are violated.

Great lecture by Olivier de Weck

[@mengxiangzhang9785]

please upload course 1. Systems Engineering Overview and Stakeholder Analysis, thanks.

[@shenyang2007]

ocw.mit.edu/courses/aeronautics-and-astronautics/16-842-fundamentals-of-systems-engineering-fall-2015/lecture-notes/ there are lecture notes for the 1st part of the course, I think that's useful.

thank you

Thank you for uploading this to youtube. Very helpful. The audio could be better though...

[@KonstantinKavruk]

On the difference between requirements and specifications: unfortunately, English is a fuzzy language, as you can "specify requirements", therefore i've personally seen a "Requirements Specification" document in the automotive field

[@jadamuzg1]

In the example of the microwave, the weight was listed as a spec, but what if there's a requirement that states: "The microwave shall weigh a maximum of 45lbs." What category is that now?

[@general9064]

Requirements. Specs are only known when the product is out.

[@muhammadsiddiqui2244]

Constraint

[@rickynave]

Is there a mathematical way to model requirements and specification? Because as is, the current distinction given seems ambiguous. E.g. If I included "The microwave should be made of stainless steel" then I would have a requirement instead of part of a specification as in the example around minute 24. Is there a precise model? Thanks! :)

[@tomlangfeldt8684]

It is unambiguous so it is a specification, being precise enough in the given context is another story

[@BlackmesaofIND]

Look up Axiomatic Design

[@tommyp3611]

In many Project Technical Specifications I have seen are essentially just requirements. This is spinning me out.

[@davehaaww8881]

This is also an academic exercise. Professor is making distinctions. In business (which are controlled by contracts) these terms can be defined at the beginning of the contract.

[@mutiur7396]

They make new things so for them these are different for businesses where customer are different but products mainly same both are same

[@attilaviniczai7215]

Shall -> Must avoids misunderstanding.

[@shenyang2007]

I want to watch part 1 of the course...

[@mitocw]

Sorry, session 1 and 12 were not recorded! To see what we do have, visit the course on MIT OpenCourseWare at ocw.mit.edu/16-842F15.

[@shenyang2007]

quite good information，thanks.

YES!!!!!

audio almost makes this unwatchable.

IllICITGRYNE my thoughts as well. There’s a difference in volume between mics and it’s huge

Great lecture!

[@arunibasu5738]

The camera should focus on the student who is speaking.

[@mitocw]

Two main reasons students aren't recorded: Intellectual Property (IP) and recording setup. 1) IP: Students aren't normally recorded. To record students, their permission must be secured for publication. 2) Most cameras for recording are setup to capture the instructor and the chalk.white boards. Recording students requires extra production work.

Are you serious when you say that people are not well medically and professionally trained in Africa

[@jeanpotter2163]

That was not what he said … he said “may” not be … just as training could be not as extensive in rural areas of any major industrial country.

Hey MIT u need quality control .The voice is not clear for EPF1 Room. This has made this video unwatchable.

MIT: So incompetent they can't record clean audio.
