Delphi Method:

The Delphi method is a flexible and adaptive research methodology used by many different types of graduate students in many different settings. A key attribute of the Delphi method is that it is an iterative process that gathers and synthesis the judgments of experts using a set of data collection and analysis methods incorporated with feedback. (Skulmoski, 2007)  The Delphi method is most appropriate when used as an instrument of research when the knowledge about a problem is incomplete. However, there may be times when its use is not suitable for research in computer science and information technology (Skulmoski, 2007).

Sometimes an example from a case study can help understand how a methodology is used. In computer forensics, the investigation of e-crime can be complex. Many legal issues surface in the act of obtaining and presenting evidence. Australian researchers used the Delphi method to identify computer forensics' main legal problems. Their approach began by identifying 30 experts representing police, regulators, and consultants and used a three-round Delphi study that included brainstorming and rating findings. (Skulmoski, 2007).  This study provided consistent positive results; however, it was discovered that it was difficult to quantify someone as an expert. A question I have from learning about the Delphi method is to ask, “What qualifies someone as an expert?” How many qualified experts do you need to have a study to be considered valid? I also noticed a pattern when reviewing several case studies. Each use of the Delphi method started with identifying subject matter experts, and facilitating three rounds of brainstorming sessions, either interviews or surveys. Those members were always asked to rank the results produced by their group. After studying the Delphi method, I have concluded that it is a worthwhile quantitative technique that can apply to the computer science field of research. 

Structure Design Process 

A unique consensus-oriented methodology is the structured design process. This methodology uses a democratic design perspective for developing consensus and leading to the remediation of complex sociotechnical problems shared by the stakeholders (Jones, 2008). Consensus can be a challenging goal to achieve when working with a group of people.   If we compare and contrast the Delphi methodology with the structure design process, we see that they both share the use of groups and a voting or ranking technique. However, these methods are different in that the structured design process develops ownership of an implementation plan by the group members. In other words, by defining the problem and agreeing that the issue needs to be solved, the group then takes ownership of the plan to solve it. I had an opportunity to use this method today while facilitating the design of a cybersecurity improvement plan that was the output of a recent cybersecurity risk assessment I had performed. In facilitating the session by engaging a team and leading the team to agree on what the problem is and deciding that they need to be solved, we were able to overcome many complex cultural issues and get our plan built and signed off on by the team and its executive sponsor. This occurred all in one session, which is a good outcome.

This is driven by the need for individual accountability for their actions to differentiate the group members from one another and regulate access to resources. In the field of cybersecurity, personal identification falls under the domain of access controls. "Access control is a way of limiting access to a system or physical or virtual resources. In Computing, access control is a process by w...

 Unit 10 DB 1 Video Click here:> https://animoto.com/play/tNcfS42i5NX0XEP6bsROJQ Hello Futuring and Innovation Enthusiast.   I am excited to share my truly awesome video highlighting the key components of my socio-technocal plan which highlights my truly imaginary and far fetched vision of a future in which all humans would utilize a new access control device that would incorporate some of the technologies of today such as a user id, single sign on and biometric identifiers but one that also includes a futuristinc design where a computer chip is embedded in a persons arm and this chip is coded to the persons DNA.  With the DNA coding the chip could only be used by them.  The futuring innovation would also include a new form digital certificates that are built on quantum computing and unbreakable.   Preview: 1. A chip would be coded to a persons DNA, 2. A digital certificate would be created using quantum cryptorgraphy and using the persons DNA code ...

 Unit 8 DB 1  The impact of disruptive technology: It was the year 2005, and Eastman Kodak had just celebrated a banner year with $11, 895,000,000. In revenue. Much to its dismay, that would be its best year in recent history. From 2005 to 2012, their revenue declined until it hit its bottom at $812,000,000. Since then, its revenue has remained relatively flat (Statista, 2022).  This is a case study of how good management practices can have a negative impact if an organization does not invest in disruptive technologies. Perhaps this very concept can seem counterintuitive, but the idea is simple. Kodak was a successful company that was the incumbent organization in the digital camera revolution. It had most of the filmmaking market share and fine-tuned its processes to be efficient. Kodak’s management team was an example of “Christensen’s theory of disruptive technologies (Lucas, 2009). This theory suggests that managers do not invest in disruptive technologi...
