Software bug

Principles of Software Engineering Principles that are used in the software development are: • The quality of the software must be high. So that the software can be easily learnt and used by the user. • To design the accurate solution of the software, firstly determine the problem issues related to the software, then write down all the requirements. • The people that are involved in the software development should be highly skilled so that they are able to make good quality software. • Choose…

was developed as a solution to Ad-hoc development methodologies. • A staged development model • Stages will be completed one after the other. • Subsequent stage can be started once the previous one is completed only. • Waterfall model follow software development process in a linear sequential. • This model phases are do not overlap. Principle of Waterfall Methodology The waterfall model describes 6 phases. I. Requirement gathering. All the required functions and requirements are…

Personal Business Model Key Resources I am very interested in Mathematics, Physics, and Logic. These interests make me very logical, precise, and thoughtful, which are useful skills in my line of work. I work in Software Development; therefore, I am obviously also interested in Computer Science. Being a female with these interests makes me relatively unique in my field. Currently, I am the only female on the entire development staff in my company. Sometimes, I view this as a challenge to my…

M4D1 I. Why do you think it is much more expensive to fix a security vulnerability late in the software life cycle, compared to early? It is almost always more costly to redo or rework something than to do it correctly in the first place. Years ago when I got my first Solaris system administration job, the Navy had the view that any job the Navy did not have official schools for could be learned via OJT (on the job training). So for my first year, I learned everything I could about…

product team from Waterfall to Agile and briefly provide the rationale behind each of them. Two key changes introduced by Greg Adams-Woodford to move his team from Waterfall to Agile were the eradication of offshore software developments teams and a transition to in-house software developers in Arizona, as well as the combination of the QA and development teams with extensive cross training in their respective specialties. The rationale behind the transition of offshore to in-house…

6 PERSONALITY ISSUES OF THE SOFTWARE TEAM Now let’s consider some of the issues that could arise in the team that developing software projects. I tried to describe most common problems that concern individuals and that can be resolved by implying described leadership styles. Part of the problems concerns more or less traditional issues as interpersonal relationships and personality characteristics. Though, I also observe relatively new issue that arose dramatically in the last 20 years with…

Established in 1981by Mr N.R Narayana Murthy and six engineers in Pune, over the years has catalyzed some of the major changes that have led India emergence as a global destination for software service talent. Infosys has emerged into leading multinational corporation that provides business consulting, information technology, software engineering and outsourcing services. Infosys is also…

A frame work for assesing poka-yoke device According to this article the framework assesses the processes of the design, operation and maintenance of poka-yoke devices. The framework includes a scoring system; background in both lean production and human factors is required to apply the framework. (https://www.sciencedirect.com/science/article/pii/S0278612512000313) Enabling Poka-Yoke Workflows with the AristaFlow BPM Suite This tool gives idea into the AristaFlow BPM Suite – a next generation…

The Proposed Hybrid System and its Control Strategy The simulation results of the PV/WT/PEMFC/battery hybrid system using ANN and fuzzy logic are discussed in this section. Simulation results are obtained by developing a detailed MATLAB/Simulink software package, as shown in Figure 8.5. Fig. 8.5 - Hybrid power system simulation model The specifications of the renewable power sources used are given in Table 8.1 PV Sharp’s (NU-180) at (1kW/m2, 25o C) Wind turbine Maximum power (Pm) 180 (W) Peak…

caused the Ariane 5 was a design error, namely of an Operand Error. The report says, “The exception was detected, but inappropriately handled because the view had been taken that software should be considered correct until it is shown to be at fault” (Lions, 1996). This view manifested itself in the use of extant software from Ariane 4 that was used for Ariane 5 because, to simplify, it worked well for Ariane 4 despite this previous flight having a different flight pattern and other design…
