-00:00:00,120 --> 00:00:03,220
-After recapping the three major issues that characterize a software crisis
-
-2
-00:00:03,220 --> 00:00:05,626
-let's see what was the evidence that there was indeed a
-
-3
-00:00:05,626 --> 00:00:07,900
-crisis. So what I want to discuss now is the result
-
-4
-00:00:07,900 --> 00:00:11,060
-of a study performed by Davis in 1990s. So in even
-
-5
-00:00:11,060 --> 00:00:13,670
-more recent times than the 60s and the 70s. And the
-
-6
-00:00:13,670 --> 00:00:17,280
-study was performed on nine software projects that were totaling a
-
-7
-00:00:17,280 --> 00:00:20,990
-cost around $7 million and I'm going to show you how this
-
-8
-00:00:20,990 --> 00:00:25,190
-projects went using this representation, this pi representation, in which I'm
-
-9
-00:00:25,190 --> 00:00:27,520
-going to discuss what each of the segment of the
-
-10
-00:00:27,520 --> 00:00:30,010
-pi represent. So let's start looking at the first one.
-
-11
-00:00:30,010 --> 00:00:32,920
-This is a software that was usable as delivered. Other
-
-12
-00:00:32,920 --> 00:00:36,590
-software was delivered, and usable, either after some changes or
-
-13
-00:00:36,590 --> 00:00:41,080
-after some major modifications, so within additional costs involved.
-
-14
-00:00:41,080 --> 00:00:43,530
-But the striking piece of information here is that the
-
-15
-00:00:43,530 --> 00:00:46,890
-vast majority of the software, so these two slices, were
-
-16
-00:00:46,890 --> 00:00:50,250
-software that was either delivered but never successfully used or
-
-17
-00:00:50,250 --> 00:00:53,730
-software that was not even delivered. And this corresponded
-
-18
-00:00:53,730 --> 00:00:57,500
-to five over the seven total million dollars for
-
-19
-00:00:57,500 --> 00:01:00,050
-all the projects. So clearly, this shows a pretty
-
-20
-00:01:00,050 --> 00:01:03,910
-grim picture for software development and its success. In short,
-
-21
-00:01:03,910 --> 00:01:06,410
-there was clear evidence the software was becoming to
-
-22
-00:01:06,410 --> 00:01:08,990
-difficult too build and that the software industry was facing
-
-23
-00:01:08,990 --> 00:01:11,190
-a crisis. And this is what led to the
-
-24
-00:01:11,190 --> 00:01:15,130
-NATO Software Engineering Conference that was held in January 1969,
-
-25
-00:01:15,130 --> 00:01:19,100
-which is what we can consider the birth of software engineering. And what
-
-26
-00:01:19,100 --> 00:01:23,080
-I'm showing here is a drawing of the proceedings for that conference. And if
-
-27
-00:01:23,080 --> 00:01:26,020
-you look at the class notes you can see a link to the actual
-
-28
-00:01:26,020 --> 00:01:27,640
-proceedings, in case you are interested in
-
-29
-00:01:27,640 --> 00:01:29,180
-looking at the issues that were discussed.
