The document discusses the Test Process Improvement (TPI) NEXT model. It describes how the model divides testing into 16 key areas and 4 maturity levels, and provides 157 checkpoints and improvement suggestions. The results of an assessment using the model are presented visually in a testing maturity matrix. The document emphasizes that properly defining and implementing improvements are critical steps, and discusses challenges organizations may face in the improvement process and how to address them.
Increasing business success with TPI NEXT and PointZERORik Marselis
Rik Marselis presented how TPI NEXT and PointZERO can contribute to increasing the business success of an organization by improving the testing process as well as the IT process as a whole.
Prior to this presentation Rik, together with Geoff Thompson, presented about "Why would you want to improve your test process" (also uploaded on slideshare).
This presentation was given at a conference for the test experts of the Siemens group.
Why would you want to improve your test process using TPI or TMMi?Rik Marselis
Rik Marselis and Geoff Thompson presented about why people in an IT organization would want to use methods for improving their test process.
Rik was the project leader for the creation of TPI NEXT.
Geoff was one of the founders of TMMi.
Both have contributed to ISTQB.
Both models can be used for test process improvement. This presentation gives an overview of the reasons why one would want to improve. After that Geoff and Rik both elaborated on the details of the methods and then did a comparison.

Most of the people think that quality in software development is limited to manual testing on the latest stage before releasing a product. That might be true 20 years ago in the industrial era. But current world is much more dynamic than before. Time to market became the most crucial metric nowadays. Releasing code to production need to be done faster and faster. How to maintain quality on a sufficient level in this fast paced environment? How to find a time to work on quality improvements? Those are two main questions I want to answer during this talk. Do not expect a silver bullet or even receipt to success. But definitely expect a lot of information about continuous delivery/deployment/improvements with a case studies and lessons we learned at Spotify.

Agile Testing: The Role Of The Agile TesterDeclan Whelan
This presentation provides an overview of the role of testers on agile teams.
In essence, the differences between testers and developers should blur so that focus is the whole team completing stories and delivering value.
Testers can add more value on agile teams by contributing earlier and moving from defect detection to defect prevention.
Finding Success with Test Process ImprovementJosiah Renaudin
When you go on a road trip and want to plan your journey, you need to know where you are, where you want to go, and why you want to go there. You need the same things when you want to improve your test process. It doesn’t matter whether you are agile, waterfall, or part of a Test Center of Excellence, you need to assess the current state of the process, your goal, and how to implement the improvements. Gitte Ottosen takes you through some of test process improvement frameworks—TMMI, TPI, and a low level lean approach—so you can compare the different frameworks and choose your own way. The assessment is only the foundation. It gives you an indication of your current position and can be input for a roadmap for reaching higher maturity. The most important key to success when implementing test process improvement is the people who are going to implement it. Without ownership and commitment, the process will never become an integrated part of the daily work within the teams and projects. Gitte introduces tools and practices for identifying your goal, creating your roadmap, making your journey happen—and ensuring ownership and commitment in the organization.
Shift left - find defects earlier through automated test and deploymentClaudia Ring
Do you know how much time it takes or how that translates into dollars lost every time you fix a defect in development, QA, or Production? The cost of application failures or errors increases exponentially the further into the delivery pipeline they are when found. If application defects are discovered by end users in Production, or errors cause a Production outage, the cost can be thousands per second, in addition to the intangible loss of reputation.
So how do you begin to identify defects earlier in software development and prevent them from becoming major, costly errors later on? Join Al Wagner, IBM Technical Evangelist, as he discusses how to "shift left" and;
Incorporate service virtualization and automated testing into development for a more thorough and accurate representation of application quality
Integrate deployment automation with continuous testing to remove wait times on application promotion
Adopt best practices that have proven successful for IBM customers who are currently shifting left
The concept of “shifting testing left” in the software development lifecycle is not new. Shifting testing from manual to automated and then upstream into engineering is a driving factor in DevOps and agile software development. However, Michael Nauman wonders why test automation, DevOps, and agile software development still frequently fail to deliver on their promises? Aligning and hardening your DevOps and test automation—along with streamlining your agile processes—is critical to your project. Michael shares how AutoCAD’s shifting testing left enabled improvements within their engineering team. Learn how the team increased engineering reliability and velocity, and forced process changes upstream into design and research all the way through to product support. Leave knowing why the concept of separation of concerns with regards to quality is as fundamental as the separation of code quality from product quality. Learn how the AutoCAD web team used process dogma and ruthless prioritization to combat metric idolatry and the host of other evils that hold teams back from fully realizing their potential and going beyond agile.
In this session, we would discuss what "Agile Testing" is, what are the well known methods and models of Agile Testing and what to expect on the future of Agile Testing.
Agile testing principles and practices - Anil KaradeIndicThreads
Traditional test processes are not adaptive to extensive changes in software. Agile process emphasizes on ability to adapt to changing business needs, customer collaboration, integrated teams and frequent delivery of business values. Agile is an umbrella term that describes a variety of methods including XP and Scrum.
The talk will discuss pitfalls of the traditional testing process. Traditional testing process happens very late in the SDLC Where as Agile process focuses on test-first approach. The talk will explain benefits of going agile. Principles and practices of agile process will be discussed and agile methodologies Scrum and Extreme Programming will be discussed in detail. Purpose of Scrum, its effectiveness, timings and managing the scrum will be discussed. Some of the practices for XP like Pair Programming, Test Driven Development will be discussed. The Talk will also cover the QA role in agile world. The talk will cover the implementation issues while shifting from traditional to agile process. Talk will also include an interactive game for illustration of concepts.

Abstract:
Many teams struggle with fitting in testing activities inside of a Sprint. They end up doing primarily development activities in a Sprint and push testing activities to run in dedicated testing Sprints following the coding Sprints or have a coding and testing Sprint running in parallel. However, in Scrum, the output of every Sprint is a potentially shippable product increment. This means the product increment should be well tested within the Sprint and ready to be delivered. Come to this presentation to learn how to tackle testing on an Agile team, what kind of tests to execute, what to automate and what not to automate, the different test responsibilities, and when to run which tests. Leave with a testing strategy that you can start applying the next day to gradually get a team to start testing from day 1 of the Sprint and deliver a true product increment at the end of each Sprint.

Software Testing Maturity Model and Assessment by AbstractaKalei White
Are you on the agile path to continuous testing? To achieve continuous testing, you need to do more than just buy the right tools. Abstracta helps assess where you stand and what is left to do in order to reach continuous integration and testing and then helps you in every area of quality that matters, to achieve the highest ROI.
To reduce the number of bugs during and after software development and improve the quality of the product, Shift Left Testing or Early Testing is implemented.
It is a method to push testing towards the early stage of software development like requirements defects, complicated designing, and so on.
By doing so, you uncover and solve the issues in an early testing phase before they become major.

How Atlassian's Build Engineering Team Has Scaled to 150k Builds Per Month an...Peter Leschev
Continuous integration is the lifeblood of any software house and extremely important in a fast-growing organisation like Atlassian. You'll hear about how the build engineering team have scaled their team, infrastructure and Bamboo over their four-year journey of continuous improvement to provide a build platform and services used internally within the organization. You'll hear about how the team has grown from three engineers servicing 300 Atlassians to 12 engineers handling over 1300 Atlassians, handling challenges such as balancing firefighting and project work. You'll hear how we've come from infrastructure that was a group of pets, to cattle, then to stateless machines; how we manage our internal Bamboo instances, balancing dogfooding new milestones and providing a critical service to the organization.

DevQA: make your testers happier with Groovy, Spock and Geb (Greach 2014)Alvaro Sanchez-Mariscal
Writing functional tests using Geb in a Grails application is fine for a development team. But when you have QA automation engineers, giving them access to the Grails app might not be the best solution (specially when they belong to a different team).
So the same way DevOps allow developers and sysadmins collaborate together, let’s talk about DevQA, and make them happy using a framework stack powered by Groovy.
Besides above considerations, in this talk I will show a live example on how to setup an independent project for functional tests using Gradle, Groovy, Spock and Geb.

Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Description of Key Area ”Test Strategy” on
different maturity levels
The test strategy enables the distribution of the
test efforts and resources among the test levels
and test activities.
The test strategy is used to achieve adequate
balance between analyzed product risks, test
coverage and available efforts and
resources, involving all stakeholders.
The method of the test strategy is maintained well
to ensure easy and valid application.

Editor's Notes
Many companies lose money or even their reputation because of bad quality IT-systems. When quality is bad, it sounds logical to start improving testing practices. The TPI NEXT –model is a great tool for assessing where you are and for creating a coherent roadmap for improvement.However, the improvement actions fail too often. Sometimes the plans are not realistic, the right stakeholders are not involved, or management doesn’t really support the initiatives. These – and other - potential impediments should be taken into account already from day one in the TPI assessment. In this talk, I will shortly present the TPI NEXT -model and discuss my practical experiences on how to succeed in improving - not only the test process, but also the whole software development life cycle. The topics discussed include both success stories and LFMF’s (=learn from my failure). In short, I will tell you the things you should know, but can't find in the TPI NEXT book.1. Short presentation of the structure and main points of the TPI NEXT model, including its connections to other processes in the SDLC2. Assessment of the strengths and weaknesses of the TPI NEXT Model, based on several assessments with different customers3. Tips on how to conduct a TPI assessment in such a way that when the assessment is done, everything is set up for a fruitful improvement project.
Create awarenessMostly awareness is there, because of quality problems in prod, long test & fix cycles, TODODetermine goal, scope and approachThe scope is normally a project or two, it’s important to have a limited scopeTwo different packages: full TPI or Quick ScanBe sure to agreewith the stakeholders – and understand -what the purpose of the assessment is - or is it just a nice to knowmeasurementAssess current situationFirst thing to do: choose and engage the right people to work with you – these will be your change agents later!
