Question1: Parallel tasks in waterfall method?
Thewaterfall approach has some very distinctive steps and someorganizations use very strict gate criteria (tasks and deliverablesmust be completed) before moving on to the next phase of thedevelopment cycle. Are there any tasks or deliverables in mostprojects that can be done in overlapping waterfall phases? Can you doparallel activities (at the same time) in most projects?
Usingthe waterfall software development model, there can never occur asituation where activities performed in different stages overlap.Each stage begins after the preceding phase is completed, and as suchevery stage is succinct designed towards accomplishing a given taskand objective. Nonetheless, composite projects may require a chain ofactivities, most of which can be carried out sequentially and othersthat can only be carried out in parallel (Daley, 2013). The waterfallmodel does not make good use of time, especially where the progressof one stage stops for a review process. The next phase cannot go onbefore the prior is complete, and this inefficiency is surmountedthrough overlapping stages. In this case design can commence onparticular deliverables immediately after the definition of the taskfor those deliverables is completed.
Taskscan be parallel in most projects to save time and make the maximumuse of available resources. For instance, different groups can agreeon the hardware architecture so that while one group focuses on thecreation of a system design another could be seeking and installingequipments required for the development of software, to avoid delays(Daley, 2013). Emblematically there is some point of iterativedevelopment involved in most projects.
Question2: Is the new iPhone really any better?
Whenwe think about smart phone technology the most visible device is thePhone. There have been a number of new iPhones over the years and anew iPhone is now available. Do you think the new iPhone is amajor jump in technology? Is it really better than the currentversion of the iPhone?
Itis true that the new Apple technological innovation has given birthto one of the most stylish phones in the world. The new iPhone 6 hasmany features that depart from the other smart phones in the market.Though the company has not made any significant changes to the camerahardware, it is evident that the iPhone 6 has a bigger screen withexcellent display quality (Williams,2014).
Comparedto the other iPhone 5S, its central processing unit and random accessmemory is leap and bounds ahead. It has got A8 20NM, 20 percentfaster central processing unit and 50 percent faster GPU. Thenew Apple Smartphone brings to the market a new and faster processorreferred to as A8, which is way ahead of the A7 used in the previousmodel. The company has also altered the architecture of the phonesystem from 28nm to 20nm, which means smaller transistors can beapplied that make the central processing unit much more efficient. Italso prevent overheating while running various programmes. Theimprovement in the CPU translates to better resolution and visualeffects (Williams,2014).
Question3: Software development mythologies – waterfall approach?
Thereare a number of software development methodologies in organizationsaround the world. The Waterfall approach is a very common method inorganizations. What are the steps in the waterfall softwaredevelopment methodology?
Waterfallsoftware model is an exemplar of sequential model. The activitiescarried out in the process of software development are divided intodifferent stages, and in each stage there is sequence of tasks meantto achieve different goals. In this model, the output form one phaseare the inputs of the subsequent phase until the entire process isover (Software Testing Help, 2014). It is worth noting that one phasecommences after completion of the previous phase, and in this respectthere is no overlapping of activities. The diagram below depicts thewaterfall model.
(SoftwareTesting Help, 2014)
Inthe requirement stage are a feasibility test is carried out to see toit that requirement are testable, all requirement are captured inthis phase in the system design stage a design that takes intoconsideration the hardware and software requirements in created inthe implementation stage programmes and codes are created and testedIn the system testing stage functional and non functional testing onthe system developed is performed to ensure it conforms to therequirement in the deployment stage the relevant applications aredeployed to their respective locations and finally in the maintenancestage the various activities are conducted to ensure the system keepson running (Software Testing Help, 2014).
Question4: Is content management system good when doing dynamic website?
Thecontent management system helps the company keep its words and webpage content up to date, but does it let them change the images andweb page layout?How often should you change the layout andespecially the content on a website or web page to keep it relevantfor all people that will navigate to the page?Does this vary bytype of web site? Sales website, informational web site, companywebsite?
Doescontent management system help companies change the images and webpage layout?
Contentmanagement system allows the users to login into protected web accessway via a particular browser and change the content of in thewebsites. This includes, the videos, the text, the documents and eventhe images and page layout. All the material in the websites can bealtered through CMS. Therefore a content management system is veryimportant acquisition in the operations of a company especially whenusing the website to convey different messages to customers (Joomla,2014). Companies can continually change the image of their websitesdepending on what is believed to be the best at a particular time,and alter the page layout if need be.
Thetype of the website does not matter since content management system,gives the user a gateway to change the content on the any websites.The website administrator does not need to possess technicalknowledge to be in a position to control the contents on the site(Joomla, 2014).
Question5: Technology and automation?
Ialways ask people if they think that technology changes extremelyfast today. Would you agree that software development of newapplications is a necessary evil? As technology changes more thingscan be automated to increase an organizations operationalefficiencies. What are some of the operational efficiencies that newsystems have enabled in your organization?
Inthe modern world the most basic force for a firm’s success is theworkforce, nonetheless the way and manner in which the workforce isable to accomplish tasks in their department significantly affectsthe output and productivity of everyone. New applications and systemshave gone a long way in improving efficiency at the workplace. First,the number of errors made when performing task has been reducedsignificantly, new system have also supported faster intra and interdepartment communication that has improved the flow of work andfinally new systems continuously increase agility and speed ofadapting to changes in the new environment.
