Lean software development is a translation of lean manufacturing principles and practices to the software development domain. Adapted from the Toyota Production System , [ 1 ] it is emerging with the support of a pro-lean subculture within the agile community.
Illustration of the 4+1 Architectural View Model. 4+1 is a view model used for "describing the architecture of software-intensive systems, based on the use of multiple, concurrent views". [1] The views are used to describe the system from the viewpoint of different stakeholders, such as end-users, developers, system engineers, and project managers.
[1] [2] The trend towards agile methods in software engineering is noticeable, [3] however the need for improved studies on the subject is also paramount. [4] [5] Also note that some of the methods listed might be newer or older or still in use or out-dated, and the research on software design methods is not new and on-going. [6] [7] [8] [9]
The scaled agile framework (SAFe) is a set of organization and workflow patterns intended to guide enterprises in scaling lean and agile practices. [1] [2] Along with disciplined agile delivery (DAD) and S@S (Scrum@Scale), SAFe is one of a growing number of frameworks that seek to address the problems encountered when scaling beyond a single team.
Value-stream mapping has supporting methods that are often used in lean environments to analyze and design flows at the system level (across multiple processes).. Although value-stream mapping is often associated with manufacturing, it is also used in logistics, supply chain, service related industries, healthcare, [5] [6] software development, [7] [8] product development, [9] project ...
Lean IT is the extension of lean manufacturing and lean services principles to the development and management of information technology (IT) products and services. Its central concern, applied in the context of IT, is the elimination of waste, where waste is work that adds no value to a product or service.
Software tool support based on some mathematical formalism includes model checking, process algebras, and Petri nets. The Box Structure Method might be one such means of specifying and designing a software product. [4] Verification that the design correctly implements the specification is performed through team review, often with software tool ...
2.0 Overview of Software Reliability Growth (Estimation) Models Software reliability growth (or estimation) models use failure data from testing to forecast the failure rate or MTBF into the future. The models depend on the assumptions about the fault rate during testing which can either be increasing, peaking, decreasing or some combination of ...
