In software engineering, a software development process or software development life cycle (SDLC) is a process of planning and managing software development. It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management .
In the software development process, the top–down and bottom–up approaches play a key role. Top–down approaches emphasize planning and a complete understanding of the system. It is inherent that no coding can begin until a sufficient level of detail has been reached in the design of at least some part of the system.
Software maps "combine thematic information about software development processes (evolution), software quality, structure, and dynamics and display that information in a cartographic manner". [8] For example: The height of a virtual building can be proportional to the complexity of the code unit (e.g., single or combined software metrics).
The book explores how software development teams using Lean Software and DevOps can measure their performance and the performance of software engineering teams impacts the overall performance of an organization. [36] [14] The book discusses their research conducted as part of the DORA team for the annual State of DevOps Reports. In total, the ...
Technology strategy (information technology strategy or IT strategy) is the overall plan which consists of objectives, principles and tactics relating to use of technologies within a particular organization. [1] Such strategies primarily focus on the technologies themselves and in some cases the people who directly manage those technologies.
As the connection between application success and business success continues to gain recognition, particularly in the mobile space, application performance engineering has taken on a preventive and perfective [1] role within the software development life cycle. As such, the term is typically used to describe the processes, people and ...
In IT operations, software performance management is the subset of tools and processes in IT Operations which deals with the collection, monitoring, and analysis of performance metrics. These metrics can indicate to IT staff whether a system component is up and running (available), or that the component is behaving in an abnormal way that would ...
Published surveys on estimation practice suggest that expert estimation is the dominant strategy when estimating software development effort. [3] Typically, effort estimates are over-optimistic and there is a strong over-confidence in their accuracy. The mean effort overrun seems to be about 30% and not decreasing over time.
