Moving to lean QA? You need to use an idea presentation

Any change is hard, but moving to a lean QA organization is especially tricky. Amy Reichert continues her lean QA series with advice on implementation.

    Scrum is a collaborative Agile development framework that breaks large processes down into small pieces in order to streamline efficiency.

  • unit testing

    Unit testing is a software development process in which the smallest testable parts of an application, called units, are individually and independently scrutinized for proper operation. Unit testing is often automated but it can also be done manually.

ALM

Application lifecycle management (ALM) refers to the processes, models and tools that manage an application from idea conception through end-of-life. ALM includes the management of the software development lifecycle (SDLC) including requirements management, design, code, test, release management and software maintenance, but goes beyond SDLC and includes management of governance and operations processes. ALM tools facilitate adherence to software development processes and help to provide an integrated approach to application development.

  • site reliability engineering (SRE)

    Site reliability engineering (SRE) is the application of scripting and automation to IT operations tasks such as maintenance and support. The goal of SRE is to swiftly fix bugs and remove manual work in rote tasks.

Models and Methodologies

Software development models and methodologies describe the processes that are followed in a software development lifecycle (SDLC.) Traditional approaches include the phased waterfall methodology that includes requirements, design, implementation, verification and maintenance phases. The traditional approaches typically require that each phase is complete before the next one starts. Agile methodologies such as XP and Scrum work in shorter iterations and promote a collaborative approach where project teams include members representing business, development and test work closely together throughout the entire lifecycle.

Project Management

Software performance management is a critical component of application lifecycle management. Software applications need to be tested to see if they'll be able to withstand the anticipated load and be scalable for future growth. By including software performance management as a component of the application's lifecycle, the team can perform the testing necessary to determine the application's thresholds and proactively code for optimal performance. With software performance management included in the overall plan, performance can be predicted and eliminate any unpleasant surprises due to slow performance.

  • falsifiability

    Falsifiability is the capacity for some proposition, statement, theory or hypothesis to be proven wrong. That capacity is an essential component of the scientific method and hypothesis testing.

  • hypothesis

    A hypothesis (plural: hypotheses) is a statement that may be tested and proven to be either true or false. The hypothesis maintains the statement is true. however falsifiability -- the ability to be disproven -- is also essential to testing hypotheses, in accordance with the scientific method.

  • unit testing

    Unit testing is a software development process in which the smallest testable parts of an application, called units, are individually and independently scrutinized for proper operation. Unit testing is often automated but it can also be done manually.

Requirements

Software requirements engineering is a crucial element in software engineering. Requirements analysis includes three types of activity: eliciting requirements, analyzing requirements and recording requirements. Eliciting requirements is the task of communicating with customers, users and stakeholders to determine which functions and features of an application. In analyzing the requirements, customers, users, and stakeholders help clarify and prioritize those features and functions. Documenting requirements can be done in different ways or with different tools. Traditional methodologies use a requirements specification. Agile methodologies document requirements with use cases or user stories.

  • dependency hell

    Dependency hell occurs when a software application cannot access the additional programming it depends upon to function.

  • design thinking

    Design thinking is an iterative approach to problem solving that intentionally seeks out people with different perspectives, knowledge, skills and experience and has them work together to create a practical solution for a real-world problem. The five steps in design thinking are empathize, define, ideate, prototype and test.

  • user story

    A user story is a tool used in Agile development to capture a description of a software feature from an end-user perspective.

Security Testing and QA

Software security testing and quality assurance is used to provide protection for data managed and controlled by software applications. Security testing needs to be done to prevent harm that could result from the loss, inaccuracy, alteration, unavailability or misuse of data. Information is categorized by severity of impact and security requirements such as those that address access control, data management and access, audit trails and usage records must be validated. Security defects are often a result of non-conformance or an error or omission in the software requirements.

  • denial-of-service attack

    Denial-of-service attacks disrupt legitimate access to organizational resources, often by overwhelming a network or resource with malicious traffic.

  • obfuscation (obfu)

    Obfuscation, in general, describes a practice that is used to intentionally make something more difficult to understand. In a programming context, it means to make code harder to understand or read.

Software Testing

Software testing is used to determine whether a software application is producing the expected results. Depending on the methodology used and the type of testing that's being done, software testing can happen at any time in the software development process. There are a variety of types of tests that are performed at different stages of the software development lifecycle such as unit tests, integration tests, systems tests and acceptance tests. Each of these can be further divided into types of testing such as functional, performance, regression, or usability tests, just to name a few. There are many tools that are used in software testing both to help find defects as well as to help track defects so that the end result is a high-quality product.

    Simulator sickness is a form of motion sickness related to interacting with a simulated environment. It can be caused, for example, by discrepancies between the simulated vehicle motion in a simulator and the user's perception or expectation of motion.
