The Phased adoption method has certain pros, cons and risks [8] [4] Pros: The conversion will be done in parts. Time is available for adjustments; Negative influences that arise at the start are less critical; No ‘catch-up’ period is needed. Time for the users to adapt is longer; Technical staff can concentrate on part of the system or some ...
A simplified version of a typical iteration cycle in agile project management. The basic idea behind this method is to develop a system through repeated cycles (iterative) and in smaller portions at a time (incremental), allowing software developers to take advantage of what was learned during development of earlier parts or versions of the system.
The general steps of N-version programming are: . An initial specification of the intended functionality of the software is developed. The specification should unambiguously define: functions, data formats (which include comparison vectors, c-vectors, and comparison status indicators, cs-indicators), cross-check points (cc-points), comparison algorithm, and responses to the comparison algorithm.
This allows methods to be compared, and method fragments in the method engineering process can easily be reused. The usage of this technique is consistent with UML standards. The left side of the metadata model shows the five basic activities involved in a software development project using FDD.
When compared with traditional forms of development, PD is sometimes criticized for being costly and slow. A project may take longer if one has to engage, work and come to a consensus with local communities, than if one did not have to do these things. [22] PD may also have higher start-up costs than traditional development.
The spiral model is a risk-driven software development process model. Based on the unique risk patterns of a given project, the spiral model guides a team to adopt elements of one or more process models, such as incremental, waterfall, or evolutionary prototyping.
More recently the concept of leapfrogging is being used in the context of sustainable development for developing countries as a theory of development which may accelerate development by skipping inferior, less efficient, more expensive or more polluting technologies and industries and move directly to more advanced ones.
A number of Wikipedia articles contain pro and con lists: lists of arguments for and against some particular contention or position.These take several forms, including lists of advantages and disadvantages of a technology; pros and cons of a proposal which may be as technical as Wi-Fi or otherwise; and lists of criticisms and defenses of a political position or other view (such as socialism or ...
