1
00:00:03,350 --> 00:00:09,110
So a friend of mine does refurbishing of buildings and we were talking the other day and he was saying

2
00:00:09,110 --> 00:00:14,750
that he always has troubles with trouble with the electricians so they always say oh yeah we can do

3
00:00:14,750 --> 00:00:15,910
that in four weeks.

4
00:00:16,010 --> 00:00:20,320
And then when he comes back after the first week they've done nothing because they got four weeks you

5
00:00:20,310 --> 00:00:20,490
know.

6
00:00:20,750 --> 00:00:24,880
And then after two weeks they've done a little bit and he goes Are you going to finish this guy.

7
00:00:24,920 --> 00:00:26,750
It's gonna be if it's all going to come together at the end.

8
00:00:26,750 --> 00:00:29,300
They say these classic waterfalls you can say.

9
00:00:29,480 --> 00:00:32,810
And then when he comes back after four weeks they go oh sorry.

10
00:00:32,810 --> 00:00:33,060
Yeah.

11
00:00:33,080 --> 00:00:33,920
We had terrible trouble.

12
00:00:33,930 --> 00:00:35,390
It's gonna take six in total.

13
00:00:35,600 --> 00:00:37,580
And he said this happens every time.

14
00:00:37,780 --> 00:00:44,330
And I said to him that's just granularity because if you if you don't allow the electricians to say

15
00:00:44,330 --> 00:00:49,550
it's a four week job if you say I want to see one week if you like sprints just divide those tasks down

16
00:00:49,550 --> 00:00:55,250
into one week tasks then Firstly they've got to show you a plan that adds up to four weeks and when

17
00:00:55,250 --> 00:00:59,570
they're making that plan they might go actually we can't do it in four weeks I've now realized because

18
00:00:59,570 --> 00:01:05,150
they've had to really focus on the detail and if it is doable they can't just waste the first week because

19
00:01:05,150 --> 00:01:09,230
they got ages because they've got a deliverable into that week which is kind of what you're describing.

20
00:01:09,230 --> 00:01:15,440
So I'm thinking you can have tight control with waterfall if you granulated down to whatever size you

21
00:01:15,440 --> 00:01:15,860
choose.

22
00:01:15,860 --> 00:01:19,350
I mean you could even have every day I'm going to come and see how much you've painted.

23
00:01:19,400 --> 00:01:20,380
You know you could do that.

24
00:01:20,560 --> 00:01:20,810
Yeah.

25
00:01:21,080 --> 00:01:24,430
And so I think that's not exclusive to agile.

26
00:01:24,440 --> 00:01:29,420
I think that idea of having tight control you could have that just the same in Waterfall couldn't you.

27
00:01:29,600 --> 00:01:34,220
Well it's slightly different because you talk you know project management deals with the you know better

28
00:01:34,220 --> 00:01:36,320
than I do but with milestones and things like that.

29
00:01:37,300 --> 00:01:37,990
And so.

30
00:01:38,090 --> 00:01:43,150
But remember when you're delivering your electrician they're essentially delivering in phases.

31
00:01:43,150 --> 00:01:45,440
Yeah they're just like this is the first phase second phase.

32
00:01:45,440 --> 00:01:46,260
There's a fourth.

33
00:01:46,760 --> 00:01:50,150
And so in agile you don't deliver in phases.

34
00:01:50,300 --> 00:01:50,910
It's scrum.

35
00:01:50,960 --> 00:01:54,090
Typically you deliver iteratively and incrementally.

36
00:01:54,200 --> 00:02:00,230
And so if you were going to have your electrician work in sprints and true sprints not just like phases

37
00:02:00,230 --> 00:02:06,920
called sprints which is a very common thing that people do then the very first sprint they would have

38
00:02:07,040 --> 00:02:11,070
one room completely wired everything.

39
00:02:11,240 --> 00:02:14,860
And it would be the most valuable route you know the kitchen or something like that.

40
00:02:14,990 --> 00:02:17,030
And then they could walk in and they say OK.

41
00:02:17,030 --> 00:02:24,140
And that way if the electrician gets sick you know goes to Madrid whatever got your best room you've

42
00:02:24,140 --> 00:02:25,730
got three of your four best rooms.

43
00:02:25,730 --> 00:02:26,680
Yeah.

44
00:02:26,840 --> 00:02:27,580
So yeah.

45
00:02:27,620 --> 00:02:29,530
So that's fascinating.

46
00:02:30,200 --> 00:02:35,690
But again you'd be mad to actually use agile if you were wiring up a building because I mean I know

47
00:02:35,690 --> 00:02:39,800
the electrician could get sick or whatever but but but it could be a very inefficient way to do the

48
00:02:39,800 --> 00:02:40,410
job.

49
00:02:40,520 --> 00:02:46,010
And the thing to keep in mind which is one of the big advantages of Scrum and Agile is that if you use

50
00:02:46,010 --> 00:02:52,880
the traditional phased approach then you'd have no rooms with electricity or or you'd have like you

51
00:02:52,880 --> 00:02:54,970
know it all comes together at the end.

52
00:02:55,070 --> 00:02:59,040
So you'd have like a two weeks before you're supposed to move into your house.

53
00:02:59,240 --> 00:03:00,730
None of the electricity would work.

54
00:03:00,740 --> 00:03:03,500
And then they flip a switch in all the electricity works.

55
00:03:03,620 --> 00:03:09,200
But with agile you can actually move into your house after the first or second sprint provided that

56
00:03:09,200 --> 00:03:12,740
you're ok living in your kitchen or you can be making money if it's something that you're making that

57
00:03:12,740 --> 00:03:13,610
you can sell.
