- 3. METRICS
- 4. WHY?
- 5. ixchelruiz “Code, Performance, PM metrics is a set of measures that provide developers better insight into the code, software and the process of developing it. They have become an integral part of the software development process, and there are several tools out there that provide an extended set of numeric values, but what, how and why is being measured?”
- 13. ixchelruiz - Failures - Quality - Complexity - Assessment - Change - Cohesion - Testing - Maintainability - Refactoring - Thresholds - Performance - Reliability - Coupling - Reusability - Inheritance - Methodologies - Security - Usability - Attractiveness - Rejuvenation Object Oriented Categories
- 16. METRICS
- 21. ixchelruiz -Kirk Pepperdine “Measure! Don’t guess”
- 22. ixchelruiz -Jim Barksdale “If we have data, let’s look at data. If all we have are opinions, let’s go with mine.”
- 23. ixchelruiz “What is not defined, cannot be measured. What is not measured, cannot be improved. What cannot be improved, cannot continue to provide value.”
- 24. ixchelruiz Lord Kelvin “When you measure what you are speaking about and express it in numbers, you know something about it, but when you cannot express it in numbers your knowledge about it is of a meagre and unsatisfactory kind."
- 28. ixchelruiz –Marilyn Strathern “When a measure becomes a target, it ceases to be a good measure.”
- 30. ixchelruiz MYSTERY LETTER DELIVERED BUT NEVER RECEIVED
- 34. ixchelruiz - Reporting Bias - Selection Bias - Overgeneralization - Implicit association - Halo effect - Sampling error - Insensitivity to sample size - Correspondance bias - Blind spot bias BIAS
- 35. ixchelruiz - Reporting Bias - Selection Bias - Overgeneralization - Implicit association - Halo effect - Sampling error - Insensitivity to sample size - Correspondance bias - Blind spot bias Human Biases (data) Human Biases (collection & annotation)
- 36. ixchelruiz Reporting bias "selective revealing or suppression of information"
- 37. ixchelruiz Selection Bias “sample obtained is not representative of the population intended to be analyzed”
- 38. ixchelruiz Overgeneralization “fallacy of examining just one or very few examples or studying a single case, and generalizing that to be representative of the whole class of objects or phenomena.”
- 39. ixchelruiz Implicit association “refers to the attitudes or stereotypes that affect our understanding, actions, and decisions in an unconscious manner.”
- 40. ixchelruiz Halo effect “tendency for positive impressions of a person, company, brand or product in one area to positively influence one's opinion or feelings in other areas”
- 41. ixchelruiz Sampling bias “sample is collected in such a way that some members of the intended population have a lower sampling probability than others. It results in a biased sample, a non-random sample”
- 42. ixchelruiz Insensitivity to sample size “cognitive bias that occurs when people judge the probability of obtaining a sample statistic without respect to the sample size”
- 43. ixchelruiz Correspondance bias “tendency for people to under-emphasize situational explanations for an individual's observed behavior while over-emphasizing dispositional and personality-based explanations for their behavior”
- 44. ixchelruiz Blind spot bias “cognitive bias of recognizing the impact of biases on the judgment of others, while failing to see the impact of biases on one's own judgment”
- 48. ixchelruiz
- 54. ixchelruiz Critical Success Factors “define key areas of performance that are essential for the organization to accomplish its mission”
- 55. ixchelruiz Key Performance Indicators “critical (key) indicators of progress toward an intended result”
- 56. ixchelruiz “To focus on value, the first challenge is ensuring goals are clear and how each function contributes to those goals”
- 57. ixchelruiz Vision Mission Goal Objectives Critical Success Factor Metrics Guidance Feedback Strategic Tactical Key Performance Indicators Operational Measurements Hoshin Kanri
- 59. ixchelruiz “Measure with a clear purpose!”
