Hi this is Renan Joran

and I keep going with this series about the new product

introduction process here I'm covering the time spent in planning before starting prototyping work

so have a lot of clients come to us

and they say here's our product design idea maybe a sketch

may be very crude prototype please build a prototype ASAP well

what we found is this is really a recipe for a lot of trial

and error and sometimes going back and wasting a lot of time

so first product testing what will be required for compliance

and for reliability also of the product in the field we

need to know this from the very beginning we've had some cases where the client had not

thought of that and it was not clarified at the beginning

and then a lot of time was spent on doing design work on making prototypes

and then realizing that it would not be compliant

it means going back to square one that's a massive waste of time

so this is really something

that needs to be clarified from the very beginning um a lot of things need to be started from the beginning

okay here's an overall idea of the the process really of all this this planning

so first what is the design intent what does the designer

want to achieve with the product how is it supposed to be used in what circumstances with what objectives

and so on okay then if some design was already done by the inventor,

let's say, does a review, we can often find some potential issues.

Then really, what is possible in China?

Sometimes a design does not call for China manufacturing.

Is this really something that is a good fit for China?

Or maybe it's better done somewhere else?

Cost and compliance needs to be thought of from the beginning

if it looks like the cost of the widget is going to be ten dollars

but it's supposed to be sold on the market for eight

dollars there's a big problem okay think of the options propose

some options once things are a little bit clearer go into

the details of the design then work on the entire design and start work on the first prototype.

This is not a process that is applicable everywhere all the time

but this gives you an idea of a good process that's applicable to a lot of electronic and all mechanical products. So

if we think of a checklist for this initial planning before

prototyping what would it be first as i say design intent

has to be very clear everybody needs to grasp what it is okay

if a product supposed to be used outdoor

but this is not documented anywhere maybe the project manager knows about it

but then the purchaser doesn't know about it

and then the supplier is not going to know about it

and they're going to use materials

that are the raw materials it's just an example okay requirements need to be very specific okay

If you say the finishing has to be as good as an Apple product, this means something.

But if you say very high-end level of finishing, it doesn't mean very much.

Sometimes the inventor, the designer thinks of something that's really over-engineered.

But this doesn't make sense usually for a first version,

especially if you are doing the development of a shoestring budget and if the timelines call for a very fast go-to-market.

I already expanded on this,

but we need to be realistic what kind of product design will allow you to be done within your budget

and within your timelines.

China manufacturing yes no sometimes again it doesn't call for China manufacturing is not a good fit

so this needs to be thought about also verification

and validation two very important keywords here for quality management

and I'm mentioning this here because it needs to be planned from the beginning

so verification okay objective tests that will have to be passed by the prototype.

If a prototype is made but does not pass these objective tests, it does not pass the verification, it doesn't count.

The prototype cannot be verified and confirmed.

Similarly, when the end users play with the prototype,

give their feedback, often very subjective,

it feels right, it operates right it's got a good feeling in the hand these kind of things

if it passes then it's fine it's good

if it doesn't pass it doesn't count okay

but this needs to be communicated from the beginning because again

if the engineers don't know about this how can he make a prototype

that passes these requirements and the last concept I want to touch on is the feasibility study

if it's a new product there will be some challenging aspects

okay maybe it's a very new application of a new technology maybe the engineering team is not familiar with

that kind of applications.

Okay, do a feasibility study, sometimes it will pass, it will go through a proof of concept prototype,

sometimes maybe on CAD software, you know, ProEngineer and the others,

do some simulations to see if it falls down, is it a shock like this, or if there's a torsion force,

is it going to break easily, and so on.

And also, sometimes some further design work is needed just to see a little bit more clearly into the design

and really what will the product look like and how will it work.

It's not just technical risks.

If you are the company that wants to design and develop a new product,

always keep in mind the market risk is what kills most startups okay you might make something

that works very well but that people are not ready to buy

or maybe not buy for that kind of price

so it might make sense to make what they call an MVP in the lean startup approach by the way

if you haven't read this book

I would advise you you grab a copy it will help

you think of what what the first version of your product should be

and how to discover what your key users typical users really need

and want to buy okay so a lot of planning here and and poor planning will lead to a failed project.

So take this very seriously.

Okay, that's the end of this video.

I hope you like it.

Thank you.

Phương Pháp Shadowing Là Gì?

Shadowing là kỹ thuật học ngôn ngữ có cơ sở khoa học, ban đầu được phát triển cho chương trình đào tạo phiên dịch viên chuyên nghiệp và được phổ biến rộng rãi bởi nhà đa ngôn ngữ học Dr. Alexander Arguelles. Nguyên lý cốt lõi đơn giản nhưng cực kỳ hiệu quả: bạn nghe tiếng Anh của người bản xứ và lặp lại to ngay lập tức — như một "cái bóng" (shadow) đuổi theo người nói với độ trễ chỉ 1–2 giây. Khác với luyện ngữ pháp hay học từ vựng bị động, Shadowing buộc não bộ và cơ miệng phải đồng thời xử lý và tái tạo ngôn ngữ thực tế. Các nghiên cứu khoa học xác nhận phương pháp này cải thiện đáng kể phát âm, ngữ điệu, nhịp điệu, nối âm, kỹ năng nghe và độ lưu loát khi nói — đặc biệt hiệu quả cho người luyện IELTS Speaking và muốn giao tiếp tiếng Anh tự nhiên như người bản ngữ.
