+00:00:00,090 --> 00:00:01,970

+The third category of mistakes that I want to

+

+2

+00:00:01,970 --> 00:00:04,970

+mention is product-related mistakes. A

+

+3

+00:00:04,970 --> 00:00:07,360

+typical example of product-related mistake

+

+4

+00:00:07,360 --> 00:00:11,010

+is gold plating of requirements. And what that means is

+

+5

+00:00:11,010 --> 00:00:13,710

+basically is that it's very common for projects to have

+

+6

+00:00:13,710 --> 00:00:17,230

+more requirements than they actually need. For example, marketing might

+

+7

+00:00:17,230 --> 00:00:19,090

+want to add more features than the ones that are

+

+8

+00:00:19,090 --> 00:00:21,460

+actually needed by the users. And of course having more

+

+9

+00:00:21,460 --> 00:00:25,720

+requirements lengthens the project's schedule in a totally unnecessary way.

+

+10

+00:00:25,720 --> 00:00:29,250

+Feature creep is another common mistake and consists in

+

+11

+00:00:29,250 --> 00:00:32,140

+adding more and more features to a product that were

+

+12

+00:00:32,140 --> 00:00:34,650

+not initially planned and are not really needed in most

+

+13

+00:00:34,650 --> 00:00:38,360

+cases. And here there is evidence that the average project

+

+14

+00:00:38,360 --> 00:00:41,180

+experiences about a 25% growth in the number of

+

+15

+00:00:41,180 --> 00:00:44,330

+features over its lifetime which can clearly highly effect The

+

+16

+00:00:44,330 --> 00:00:47,580

+project schedule. Finally, if you're working on a project that

+

+17

+00:00:47,580 --> 00:00:50,760

+strains the limits of computer science. For example, because you

+

+18

+00:00:50,760 --> 00:00:53,350

+need to develop new algorithms for the project, or you have

+

+19

+00:00:53,350 --> 00:00:56,670

+to use new techniques. Then that project might be more research than

+

+20

+00:00:56,670 --> 00:00:58,450

+actual development. And therefore, it

+

+21

+00:00:58,450 --> 00:01:00,600

+should be managed accordingly. For example,

+

+22

+00:01:00,600 --> 00:01:03,910

+by taking into account that you will have a highly unpredictable schedule.
