Why IT needs lean

1. Why IT needs lean
by

2. Improvement

3. Why would we need that?

4. Well…

5. What exists today ?

8. CMMi

9. Do our customers have fewer
incidents for that reason?

10. No !

11. Why ?

12. Let’s have a look…

13. … a closer look

14. First

15. There is a customer

16. And the customer has some…

17. Requirements

18. That we transform into…

19. Specifications

20. Specifications are checked
with the customer

21. The customer
specifies his
requirements

22. Back to writing
specifications

23. Then, we have…

24. Development

25. Second check with the
customer

26. The customer changes
opinion

27. (Time has passed since
the initial requirements)

28. Back to development

29. (Or was it a specification
problem?)

30. With some luck, we should
be able to start…

31. … The tests

32. But then…

33. We find bugs

34. Back to development

35. More tests

36. One day we will get to…

37. Pre-production

38. It’s now time for…

39. … a third check with the
customer

40. Bugs are found with the real
data

41. Back to development

42. Functional bugs are also
found

43. Back to specs

44. Back to development

45. And more tests

46. Then back to pre-production

47. In the end, we should
be …

48. In production!

49. Yes!

50. But then, we get…

51. Incidents!

52. That we know how to fix…
(Choose the best one)

53. Restart a job

54. Restart a job
Add disk

55. Restart a job
Add disk
Add CPU

56. Restart a job
Add disk
Add CPU
Add _________

57. Then…

58. (the production is redelivered)

59. New incident!

60. Now it’s time for a…

61. Problem analysis!

62. That will allow us to find…

63. The good solution !

64. (back to development)

65. (tests)

66. (pre-production)

67. (in production)

69. The customer is still waiting…

70. Finally you realise that!

71. Now it’s time for …

72. The task force!

73. Problem analysis again!

74. (back to development)

75. (tests)

76. (pre-production)

77. (in production)

78. …

80. Déjà vu?

81. Not strange that…

82. Specification teams

83. Developers

84. Test teams

85. Pre-production teams

86. Production teams

87. Incident management teams

88. Problem management teams
