In computer science, specifically software engineering and hardware engineering, formal methods are a particular kind of mathematically rigorous techniques for the specification, development and verification of software and hardware systems.
For example, proofs of properties or refinement from the specification to a program may be undertaken.
In computer science, formal specifications are mathematically based techniques whose purpose are to help with the implementation of systems and software.
Another approach is to use probably correct refinement steps to transform a specification into a design, which is ultimately transformed into an implementation that is correct by construction.
Framework for developing, delivering, and sustaining products in a complex environment, with an initial emphasis on software development, although it has been used in other fields including research, sales, marketing and advanced technologies.
Although not originally a core scrum practice, backlog refinement (formerly called grooming) was added to the Scrum Guide and adopted as a way of managing the quality of product backlog items entering a sprint.
In software development, agile (sometimes written Agile) practices include requirements discovery and solutions improvement through the collaborative effort of self-organizing and cross-functional teams with their customer(s)/end user(s), adaptive planning, evolutionary development, early delivery, continual improvement, and flexible responses to changes in requirements, capacity, and understanding of the problems to be solved.
Teams should be prepared to move forward with only those stories in which they have confidence, then during the iteration continue to discover and prepare work for subsequent iterations (often referred to as backlog refinement or grooming).
A specification often refers to a set of documented requirements to be satisfied by a material, design, product, or service.
An alternative approach is to use provably correct refinement steps to transform a specification into a design, and ultimately into an actual implementation, that is correct by construction.
Method of software development based on B, a tool-supported formal method based on an abstract machine notation, used in the development of computer software.
Compared to Z, B is slightly more low-level and more focused on refinement to code rather than just formal specification — hence it is easier to correctly implement a specification written in B than one in Z. In particular, there is good tool support for this.
The refinement calculus is a formalized approach to stepwise refinement for program construction.
Finnish computer scientist.
Back originated the refinement calculus, an important approach to the formal development of programs using stepwise refinement, in his 1978 PhD thesis at the University of Helsinki, On the Correctness of Refinement Steps in Program Development.
Any operation that takes a computer program and generates another program.
A generalisation of semantic equivalence is the notion of program refinement: one program is a refinement of another if it terminates on all the initial states for which the original program terminates, and for each such state it is guaranteed to terminate in a possible final state for the original program.
