The document describes a troubleshooting skills manual. It discusses the main goal of troubleshooting as identifying the cause of a problem. The key tasks involved are systematically testing suspect components through deduction, isolation, and elimination until the fault is identified. Effective troubleshooting relies on skills like applying technical knowledge to deduce likely causes, isolating components logically to test functionality, and using a structured process to rule out potential issues.

Root Cause Analysis (RCA) is a process to understand the underlying causes of problems in order to prevent future issues. It involves asking "Why?" repeatedly to determine the root cause, typically requiring around 5 iterations. RCA principles include making it continuous, focusing on prevention over blame, and always searching for the root cause rather than stopping at surface explanations. Common leakage reasons for defects include requirements ambiguity, insufficient testing, and outdated test coverage. RCA stats can be used to measure quality and determine where to focus process improvements.
Operating Excellence is built on Corrective & Preventive Actions
This document provides an overview of Corrective Action Preventive Action (CAPA) and how to implement an effective CAPA process. It defines CAPA and explains the difference between corrective and preventative actions. It outlines the benefits of a mature CAPA system, including increased quality, reduced costs from problems, and improved customer satisfaction. The document then discusses various tools that can be used in the CAPA process, including root cause analysis techniques like 5 Whys, fishbone diagrams, and Pareto charts to identify causes and prioritize actions. Examples are provided for how to apply these tools to analyze specific business processes.
The document discusses moving from a defect reporting approach in software testing to a defect prevention approach using lean principles. It notes that preventing defects from the beginning is far more effective than finding faults later. It asks questions about the current state of testing and defect handling to determine opportunities to focus more on prevention activities like exploratory testing earlier and removing the root causes of defects.
Risk-based testing is a commonly-performed technique for prioritizing tests that must be performed in a short time frame. However, this technique isn't perfect and has some risks in itself. This presentation lists 13 ways a tester can be "fooled by risk."

The 8D problem solving process is an approach to systematically solve problems. It involves 8 steps: 1) establishing a team, 2) describing the problem, 3) implementing containment actions, 4) identifying the root cause, 5) verifying countermeasures, 6) implementing permanent corrective actions, 7) preventing recurrence, and 8) congratulating the team. The process provides a structured way for a team to understand the problem, contain it, determine and address its root cause, and ensure it does not happen again.
ABOUT THE TRAINING PROGRAM :-
Root cause analysis (RCA) is a class of problem solving methods aimed at identifying the root causes of problems or events. The practice of RCA is predicated on the belief that problems are best solved by attempting to address, correct or eliminate root causes, as opposed to merely addressing the immediately obvious symptoms. By directing corrective measures at root causes, it is more probable that problem recurrence will be prevented.
DESIGNED FOR :-
Managers, Engineers, Supervisor and officers engaged in maintenance operation and engineering activities.
OBJECTIVE :-
At the end of the training program, participants will be able
- To gain a basic understanding of the problem solving and decision-making process and the applicable quality tools that support this process.
- To develop specific competencies to use the structured approach to problem solving and decision making and the supporting quality tools.
TRAINING PROGRAM COVERAGE :-
- Basic knowledge about RCA program.
- What are the RCA tools ?
- More about Why- Why analysis ?
- Videos and case studies on RCA
'Houston We Have A Problem' by Rien van Vugt & Maurice Siteur
Prevent the surprise, become a pro-active test manager. Too often projects suddenly seem to spin out of control. Challenges and risks keep stacking up and the defect count grows exponentially. At the same time, management can put pressure on you, asking when testing will be completed.
A surprise? Not really, defects only paint half the picture. The test effort, after all, is primarily determined by the number of tests that need to be completed. For an on the spot status of testing and accurate view on the quality and risks of the entire project we need to organize the test process to provide flexible, up-to-date metrics and trends on a daily basis. E.g. we need a view on baseline vs. actuals and ETC’s on test cases. Advanced metrics will provide answers on what needs to be done tomorrow to stay on track, the location and root cause of issues and who is required to take action. Also the test effort remaining for an acceptable product (or a specific risk level) can be estimated fairly accurately.
In addition early involvement and preparation in the development life cycle, performing test intakes rather than reviews, will help you bridge the gap between different development teams and allows you to verify consistency between business requirements, the integration model, functional specifications and technical specifications. It facilitates knowledge transfer and provides you with the “story” behind the specifications. This will help prevent structural issues in an early stage and avoid blocking issues during test execution.
This presentation combines daily test metrics and trends with test process dynamics and shows you how to become a “pro-active” test manager. Even better you can apply it tomorrow and take your test process to a distinct higher maturity level.
Michael Roar Borlund & Christian Carlsen - Real Exploratory Testing, Now With...
Exploratory testing approaches like "hotspot" and "coffee break" were presented as ways to optimize time spent testing and find more defects when performing exploratory testing in a service-oriented architecture (SOA). The "hotspot" approach resulted in finding more defects on average but took more time per defect. The "coffee break" approach found fewer defects but in less time. Both approaches provided broader test coverage and additional knowledge of the system compared to traditional testing. The presentation concluded that using a customized mix of both exploratory testing methods can minimize wasted time and add value to a project.

Two traditional definitions:
Conforms to requirements.
Fit to use.
Verification: checking software conforms to
its requirements (did the software evolve
from the requirements properly; does the software “work”?)
Is the system correct?
Validation: checking software meets user requirements (fit to use)
Are we building the correct system?
What Is “Quality”?
4
Testing: executing program in a controlled environment and “verifying/validating” output.
Inspections and reviews.
Formal methods (proving software correct).
Static analysis detects “error-prone conditions.”
Some “Error-Detection” Techniques (finding errors)
5
Error: a mistake made by a programmer or software engineer that caused the fault, which in turn may cause a failure
Fault (defect, bug): condition that may cause a failure in the system
Failure (problem): inability of system to perform a function according to its spec due to some fault
Fault or failure/problem severity (based on consequences)
Fault or failure/problem priority (based on importance of developing a fix, which is in turn based
on severity)
Faults and Failures

Activity performed for:
Evaluating product quality
Improving products by identifying defects and having them fixed prior to software release
Dynamic (running-program) verification of program’s behavior on a finite set of test cases selected from execution domain.
Testing can NOT prove product works 100%—even though we use testing to demonstrate that parts of the software works.

This document provides an overview of Root Cause Analysis (RCA) training. RCA is an objective methodology used to determine the underlying causes of problems within an organization. The goals of RCA are to analyze problems to identify what happened, how it happened, and why it happened, in order to develop actions to prevent reoccurrence. RCA training teaches techniques to identify causes of problems, solve issues, and prevent future issues, saving organizations time, money, and resources. RCA is applied to analyze a variety of events like accidents, errors, and failures to develop preventative actions.
RCA and TEA are processes used to analyze defects and improve quality. RCA seeks to determine the root cause of defects to prevent future occurrences, while TEA aims to help testing teams detect defects earlier. Both utilize defect data, with some common fields like reason introduced and development phase. RCA data is collected for all defects to drive process improvements, while TEA examines samples to spot trends and focus test improvements. Collecting and analyzing this data can help reduce costs by finding and fixing defects earlier.
The RCCA PPT is an excellent training tool to implement into your functional group or business.
It basically forces you to peel the onion on a failure as far back until you’ve reached the root cause whereas in some cases it could be several.
It incorporates the 5 whys and the problem solving technique.

Three common RCA tools are described: 5 Why's analysis involves repeatedly asking why to drill down to the root cause; affinity diagrams group related causes to identify major causes; and fishbone diagrams illustrate the relationship between causes and effects. The document encourages using the appropriate tool based on the problem complexity and provides examples of applying each tool.
This document discusses developing a business case and architecture. It recommends starting with requirements to define the logical and physical architecture and detailed designs. User stories should capture requirements, such as vision, customer experience, solutions, and components. A roadmap charts the integration of products over quarters. A project plan lays out interviewing owners, gathering scenarios, documenting stories, and mapping them to scenarios. A contact checklist is provided to validate figures. The conclusion emphasizes informing stakeholders throughout the process.
Composer has triggered a renaissance in the PHP community, it has changed the way we deal with other people’s code and it has changed the way we share our code. We are all slowly moving to using Composer, from Wordpress to Joomla and Drupal and frameworks in between. But many of us mistreat composer, follow outdated practices or simply lack a few tricks. In this session i’ll get you the low down on how to use composer the right way.

Chapter 10:
Testing and Quality
Assurance
1
Understand quality & basic techniques for software verification and validation.
Analyze basics of software testing and testing techniques.
Discuss the concept of “inspection” process.
Objectives
2
Quality assurance (QA): activities designed
to measure and improve quality in a product— and process.
Quality control (QC): activities designed to validate and verify the quality of the product through detecting faults and “fixing” the defects.
Need good techniques, process, tools,
and team.
Testing Introduction
similar
3
Two traditional definitions:
Conforms to requirements.
Fit to use.
Verification: checking software conforms to
its requirements (did the software evolve
from the requirements properly; does the software “work”?)
Is the system correct?
Validation: checking software meets user requirements (fit to use)
Are we building the correct system?
What Is “Quality”?
4
Testing: executing program in a controlled environment and “verifying/validating” output.
Inspections and reviews.
Formal methods (proving software correct).
Static analysis detects “error-prone conditions.”
Some “Error-Detection” Techniques (finding errors)
5
Error: a mistake made by a programmer or software engineer that caused the fault, which in turn may cause a failure
Fault (defect, bug): condition that may cause a failure in the system
Failure (problem): inability of system to perform a function according to its spec due to some fault
Fault or failure/problem severity (based on consequences)
Fault or failure/problem priority (based on importance of developing a fix, which is in turn based
on severity)
Faults and Failures
6
Activity performed for:
Evaluating product quality
Improving products by identifying defects and having them fixed prior to software release
Dynamic (running-program) verification of program’s behavior on a finite set of test cases selected from execution domain.
Testing can NOT prove product works 100%—even though we use testing to demonstrate that parts of the software works.

Fluttercon 2024: Showing that you care about security - OpenSSF Scorecards fo...Chris Swan
Have you noticed the OpenSSF Scorecard badges on the official Dart and Flutter repos? It's Google's way of showing that they care about security. Practices such as pinning dependencies, branch protection, required reviews, continuous integration tests etc. are measured to provide a score and accompanying badge.
You can do the same for your projects, and this presentation will show you how, with an emphasis on the unique challenges that come up when working with Dart and Flutter.
The session will provide a walkthrough of the steps involved in securing a first repository, and then what it takes to repeat that process across an organization with multiple repos. It will also look at the ongoing maintenance involved once scorecards have been implemented, and how aspects of that maintenance can be better automated to minimize toil.

Quality Patents: Patents That Stand the Test of TimeAurora Consulting
Is your patent a vanity piece of paper for your office wall? Or is it a reliable, defendable, assertable, property right? The difference is often quality.
Is your patent simply a transactional cost and a large pile of legal bills for your startup? Or is it a leverageable asset worthy of attracting precious investment dollars, worth its cost in multiples of valuation? The difference is often quality.
Is your patent application only good enough to get through the examination process? Or has it been crafted to stand the tests of time and varied audiences if you later need to assert that document against an infringer, find yourself litigating with it in an Article 3 Court at the hands of a judge and jury, God forbid, end up having to defend its validity at the PTAB, or even needing to use it to block pirated imports at the International Trade Commission? The difference is often quality.
Quality will be our focus for a good chunk of the remainder of this season. What goes into a quality patent, and where possible, how do you get it without breaking the bank?
** Episode Overview **
In this first episode of our quality series, Kristen Hansen and the panel discuss:
⦿ What do we mean when we say patent quality?
⦿ Why is patent quality important?
⦿ How to balance quality and budget
⦿ The importance of searching, continuations, and draftsperson domain expertise
⦿ Very practical tips, tricks, examples, and Kristen’s Musts for drafting quality applications

43. 4 methods in logically isolating
(hardware and software) faults:
simplify
shorten
compare
error for error[ ]
44. [simplify]
Process of excluding complex component and substituting
it with a basic component. “Is there a substitute or
alternative core component ?”
Example: wireless router to LAN cable; production server
to test server; setting application setting to plain vanilla
mode
45. [shorten]
Process of minimizing the process or excluding unnecessary
components without altering the intended goal. “Can this
component be taken out without altering the overall process?”
Example: remote application to local application; network
printing to local printing
46. [compare]
Process of taking suspected component and comparing it
with a known working component or environment. “Is
there a working model to compare this with?”
Example: side by side comparison; a tested component
inserted in place of a suspected fault
47. [error for error ]
Process of injecting known error into the target fault. The
sequence of the expected error compared to the original error
will help determine the location or identity of the fault. “Is there
documented and reversible error that can be applied to this
fault?”
Example: intentionally entering an incorrect password, which
came first “wrong password “ or original error ?

Efficient
Effective and Methodical approach in testing suspected components using technical deduction and logical isolation to identify problem cause.
Fault IsolationComponents with no physical boundaries needs to be logically isolated in order to test the components functionalityGoal – to identify problem causeIsolation Methods - simplify – Process of excluding complex component and substituting it with a basic component. “Is there a substitute or alternative core component ?” Example: wireless router to lan cable; OS XP to XP simple mode-shorten Process of excluding unnecessary components without altering the intended goal. “Can this component be taken out without altering the overall process?” Example: network printer to local printer; remote server to local server-Compare: Process of taking suspected component and comparing it with a known working component or environment. “Is there a working model to compare this with?” Example: - E4E : Process of injecting known error into the target fault. The sequence of the expected error compared to the original error will help determine the location or identity of the fault. “Is there documented and reversible error that can be applied to this fault?” Example:Exercise: List 5 hardware components, try to test / isolate each components using anyone of isolation methods. Then do 5 software components.Using the same State 3 components

Task or technical command
Troubleshooting efficiency depends on how fast one can logically isolate any given component. The faster you isolate and test each potential component the faster one can identify the problem cause.

Make a mental list of potential faults“if the 1st component tested is not the fault, what’s the next potential fault?”SKILL ExerciseStart with 2 faults then incrementExercise 1: Pick an error or symptom from a knowledge base, state the #1 suspected fault. Then state #2 suspected fault then increment Exercise 2: Pick an error or symptom from a knowledge base and make a mental list of all potential faults; compare your list with other AnalystAs a team suspected faults has to be the same with everybody
