Root Cause Analysis, Pareto Chart, Cause Effect Diagram
We all want to support the accomplishment of safe and trouble-free products and processes. Failure Mode and Effects Analysis has the potential to be a powerful reliability tool to reduce product design and manufacturing risk in a cost effective manner. With shorter product development times, tighter budgets and intense global competition, Design for Reliability tools such as FMEA must be applied correctly. Yet in practice, FMEA does not always achieve the expected results. Why is it that some companies have outstanding success in their FMEA application and others do not? What is the difference between well done and poorly done FMEAs? What are the essential elements of an effective FMEA process? These questions and more are answered in these three new short courses on FMEA.

Maintenance Leading and Lagging Key Performance Indicators (KPIs)Ricky Smith CMRP
“It is not possible to manage what you cannot control and you cannot control what you cannot measure!” (Peter Drucker)
Performance measurement is a fundamental principle of management. The measurement of performance is important because it identifies current performance gaps between current and desired performance and provides indication of progress towards closing the gaps. Carefully selected key performance indicators identify precisely where to take action to improve performance.
This paper deals with the identification of key performance indicators for the maintenance function, by first looking at the ways that maintenance performance metrics relate to manufacturing metrics. Since performance measurements for maintenance must include both results metrics and metrics for the process that produces the results, this document presents a representation for the business process for maintenance. The document then identifies typical business process and results metrics that can be used as key performance indicators for the maintenance function.

Measuring Quality: Testing Metrics and Trends in PracticeTechWell
In today's fast-paced IT world, companies follow “best” testing trends and practices with the assumption that, by applying these methodologies, their product quality will improve. But that does not always happen. Why? Liana Gevorgyan questions and defines, in the language of metrics, exactly what is expected to be changed or improved, and how to implement these improvements. While your project is in progress, choosing the right metrics and looking at their trends help you understand what must change to improve your methodology. Metrics—customer satisfaction, critical/blocking issues ratio with trends for each iteration, gap analysis results and improvement metrics, automation scripts, and test case coverage—and their priority are defined by assigning weight for each based on current project size, process model, technology, time, and goal. With a long list of metrics and measurement techniques, learn to drill down to what really makes sense in your organization. Develop a model that meets your needs and evaluates changes more effectively.

Introduction to Reliability and Maintenance Management - PaperAccendo Reliability
Paper for the tutorial presented at the 2014 RAMS conference.
A basic introduction to reliability and maintenance management with a focus on basic tools, approaches and creating value.
We outline a basic structure to move your organization to a proactive program.
Accelerating Your Mastery of APM Through Skills Self-Analysis - AppSphere16AppDynamics
The problem that an organization wants to solve with application performance management (APM) is spread across many divisions. Developers are needed to investigate issues hidden deep in the code. QA has to uncover performance-related issues. And operations has to deal with the day-to-day triage of production issues.
To be successful with APM and deliver on its core capabilities—including rapid deployments, solution sizing, application audit, triage, and assessments—engineers and managers need to build critical skills. In this presentation, we will explore ways to grow from a cost center to a profit center by delivering value-added services like capacity planning, 100% uptime, and rapid deployments.
Key takeaways:
o Understand APM maturity model, skill matrix, and concepts of APM as collaboration application
o Changing the perception of APM as a cost center to a profit center by delivering value-added services
o Matching these critical skills to AppDynamics features

In the process of software development, traceability is a key success factor as it ensures maintaining control over the development of products. With more and more complex devices that have software solutions integrated in them, ensuring control over the development process requires transparency and consistency. Spanning through the whole SDLC from requirements definition all the way to releasing the product, traceability ensures transparency and consistency across all artifacts.
codeBeamer's traceability features let you track all artifacts across the entire software development lifecycle, link them to the source code, and visualize dependencies across interrelated artifacts. The Traceability Browser and Matrix help identify, filter and visualize these dependencies between items across projects. All changes of artifacts can also be tracked, and versioning and baselining is available through version control systems (Git, Mercurial, SVN). codeBeamer lets you manage these items and relations across entities, projects, documents and Wikis, since all the data is based in a single repository.

We work on projects to improve reliability. There may not be the field data immediately available. Let’s explore what you can do to improve the overall program while delivering on your project. Specifically, what’s with cost and procurement?
Detailed Information: As a reliability professional we often work with a team focused on improving the reliability of single product or system. We work with the resources and capabilities of the organization. For me a reliability project is one product or line, a program is the entire organization and lifecycle. We bring specific tools and knowledge, yet rely on the overall reliability culture of an organization to be successful
The overall reliability program may or may not have the field data, root cause analysis and other element of information that allow us to effectively solve problems for a specific project. In some cases we have to work to improve the overall program while striving to create a reliable product. Let’s explore what you should do when you are building a reliability model for a new project and would like to use previous reliability history.
If the data is not available what do you do? What are your options? Let’s discuss what happens when the procurement team consistently selects the least expensive and least reliable components. What are your options? You can and should change the way entire departments do business, for the good of the project and the organization. Let’s discuss the scope of your role as a reliability engineer.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

51. Organizational Tasks
Institutionalize Reliability Tasks
It is the responsibility of engineering to achieve
reliability objectives.
Reliability methods must be integrated into
ongoing engineering procedures and tasks,
including design reviews, supplier selection, work
instructions, design procedures, etc.
2014 RAMS – Tutorial 2A - Schenkelberg

53. Organizational Tasks
Advance up the Maturity Matrix
Maturity Matrix represents stages of “maturity” of
a company with respect to
Product Requirements
Engineering
Feedback Process
Management
There are 5 stages of maturity that represent
increasing levels of organizational and
engineering capability

56. Step 1: Develop Reliability Strategic
Vision
In the words of American educator Steven Covey,
“begin with the end in mind.”
The Reliability Strategic Vision outlines the
overall vision for Reliability for the organization
or program.
It should be developed with full management
support, understood by all employees, and
integrated into work activities.
2014 RAMS – Tutorial 2A - Schenkelberg
56
57. Step 2: Perform Reliability Gap Assessment
A Reliability “Gap” Assessment is:
A comprehensive analysis of the specific “gaps” between a
company’s vision for reliability and current reliability capability
It begins with developing or understanding the company’s
reliability vision, and then analyzes the specific shortcomings to
achieving that vision.
The “gaps” are those issues or shortcomings that if closed or
resolved would move the company in the direction of achieving
its reliability vision. It is input to the Reliability Program Plan.
“Gaps” include both organizational capability and application of
reliability methods.
2014 RAMS – Tutorial 2A - Schenkelberg
57
58. Step 3: Develop Reliability Program Plan
A Reliability Program Plan (RPP) is a document that
defines the entire set of tasks that need to be
accomplished on a project or program, including
responsibility for execution, timing and resources, in
order to achieve the program reliability objectives.
The objective is to design and manufacture a highly
reliable product, on time, and in a cost effective manner.
Includes Steps A thru K
2014 RAMS – Tutorial 2A - Schenkelberg
58
59. Step 4: Execute Reliability Program Plan
Reliability Program Plan execution requires
management buy-in and support
Reliability plan tasks should be integrated into
company project planning and execution mechanisms
Provide a Work Break-Down Structure and schedule
for the RPP (who, what, when, where, etc.)
Empower reliability to raise the red flag when needed
2014 RAMS – Tutorial 2A - Schenkelberg
59
60. Step 5: Assess Program Lessons Learned
No reliability program is flawless
Maintain record of issues with development and
execution of reliability plan
Move the organization up the maturity matrix
2014 RAMS – Tutorial 2A - Schenkelberg

61. Conclusions
Developing and executing an effective Reliability
Program Plan is essential to achieving high reliability
for products and processes
By following the information in this
tutorial, companies can develop effective Reliability
Program Plans that achieve reliability
objectives, while staying within budget and timing
constraints.
