1
00:00:04,440 --> 00:00:12,600
In this lesson, we are going to talk about how Lang Smith solves the challenges in the prototyping

2
00:00:12,600 --> 00:00:13,560
phase.

3
00:00:15,510 --> 00:00:18,000
So first we are going to.

4
00:00:19,110 --> 00:00:28,290
Talk it briefly in these slides, and then we will go into a deeper mode in the next more practical

5
00:00:28,290 --> 00:00:29,070
video.

6
00:00:30,140 --> 00:00:42,860
So remember now we are focusing on how Lang Smith help the LM app development teams to solve these four

7
00:00:42,860 --> 00:00:46,610
main challenges in the prototyping phase.

8
00:00:47,780 --> 00:00:49,280
Remember the challenges.

9
00:00:49,280 --> 00:00:58,670
How to identify what is failing, how to iterate and experiment, how to compare the performance of

10
00:00:58,670 --> 00:01:03,650
different versions, and how to test the performance of a prototype.

11
00:01:05,330 --> 00:01:07,370
Regarding the first challenge.

12
00:01:07,370 --> 00:01:16,370
We are going to see this in detail in the next video, but how long chain helps us in this particular

13
00:01:16,370 --> 00:01:17,360
challenge?

14
00:01:17,930 --> 00:01:28,220
So you just need to have long Smith tracing enabled since the day one of the development of a new LM

15
00:01:28,220 --> 00:01:29,150
application.

16
00:01:29,870 --> 00:01:37,730
And if you do that, you will have a way to identify what is failing at any moment.

17
00:01:38,300 --> 00:01:41,900
So we will talk about this in more detail in the next video.

18
00:01:42,170 --> 00:01:48,320
Second challenge iterate and experiment how we do.

19
00:01:48,320 --> 00:01:50,030
We solve this challenge.

20
00:01:50,540 --> 00:01:53,330
We will talk about this in detail.

21
00:01:53,330 --> 00:01:56,060
Now I just want to highlight it.

22
00:01:56,060 --> 00:02:01,820
We will use Lang Smith Playground to iterate and experiment.

23
00:02:01,820 --> 00:02:07,310
We will see what is the Lang Smith Playground and how we use it later.

24
00:02:08,180 --> 00:02:15,170
Next challenge how to compare performance between different prototyping versions.

25
00:02:15,260 --> 00:02:18,800
How we solve this challenge.

26
00:02:18,800 --> 00:02:26,870
We will use Lang Smith comparison view to compare the performance of alternative approaches.

27
00:02:28,140 --> 00:02:34,620
And fourth, how do we evaluate the performance of our prototype?

28
00:02:35,160 --> 00:02:43,860
We will use Lang Lang Smith to create a test data set, data set, which is going to help us in our

29
00:02:43,860 --> 00:02:44,880
own evaluation.

30
00:02:44,880 --> 00:02:45,570
Okay.

31
00:02:45,570 --> 00:02:56,850
So in the next practical video, we are going to see in detail how Lang Smith help us solve the challenges

32
00:02:56,850 --> 00:02:59,880
in the different stages.

33
00:03:01,440 --> 00:03:02,250
And.

34
00:03:03,260 --> 00:03:09,710
Well, in fact, we are going to talk about the how Lang Smith solves the challenges in the prototyping

35
00:03:09,710 --> 00:03:10,430
phase.

36
00:03:11,150 --> 00:03:18,890
And once we finish that in the practical video, we will go to the next lesson, which is how Lang Smith

37
00:03:18,890 --> 00:03:22,580
solves the challenges in the beta testing phase.

38
00:03:22,580 --> 00:03:26,420
But first let's go to the practical video.
