Objective variable 2.3 3. PRINCE 2 Project management method. This double edged sword leaves the quantitative method unable to deal with questions that require specific feedback, and often lacks a human element. 1. The only way that research can turn into fact is through a process of replication. It focuses way more on individuals and how they interact rather than on the process or the tools - so communication is an essential key aspect. In few of the projects at the starting of the software development life cycle it's difficult to estimate the actual effort required. The one disadvantage of qualitative research which is always present is its lack of statistical representation. There is usually a lack of a sufficient number of comparable companies or transactions. Phases of the Software Development Life Cycle. It requires an expert project member to take crucial decisions in the meeting.

This Method is very useful for the average and below-average students. Answer: Generally, almost any topic can be approached either qualitatively or quantitatively, including those in the social sciences. It takes a lot of time to collect the data points. Disadvantages 1) Excessive Documentation- The PRINCE2 approach is infamous for requiring excessive paperwork throughout the whole project lifecycle. The Waterfall approach is, by definition, methodical. 3. 3 key disadvantages of Agile methodology Teams get easily sidetracked due to lack of processes Long-term projects suffer from incremental delivery The level of collaboration can be difficult to maintain Workdays are more than 9-to-5 blocks of timeespecially if you're a project manager. The interviewee can't provide false information such as gender, age, or race. Scrum teams sometimes have difficulty adopting the Scrum methodology because it is a big change from their traditional working methods. It does not take the project deadline into account. Incomplete Method. An experiment may reveal an anomaly that wasn't evident in observation, while observations provide nuances that can't be captured in multiple-choice surveys. Every method has its own advantages and disadvantages involving the level of abstraction, the scope of covering, etc. Sometimes, the proper meaning of words and phrases may be neglected in this method.

According to the Natural Method, as suggested by Stephen Krashen, learners acquire language best through the modified input of the teacher. But the real difficulties lie in selection, estimation and administration of samples. Interviews can be done face-to-face or via video conferencing tools. Also, system architecture or design issues may arise because not all requirements are gathered in the beginning of the entire life cycle. Project management methodologies help in streamlining a number of aspects for organizations, including: Continuously drive projects in the right direction. For assessment studies, mixed method research provides opportunities to comprehend questions of 'why' and 'how much'.Mixed method research has value in teaching and research, the researchers are warned against advocating for this method as being better than either qualitative or quantitative design (Hesse-Biber, 2010). Some weaknesses are, for instance, smaller sample size and time consuming. Researchers must also have good interviewing skills, have the courage to ask follow-up questions, and be able to form professional bonds with participants to ensure the accuracy of the data. This type of research involves developing and testing theories and hypotheses that are challenging to the researcher intellectually but may or may not be applied practically at the present time or even in future.
