Question
Overview: A group decision system is being built over a network and, because of the lag inherent to the network, is experiencing delays. For each of the situations below, suggest the longest acceptable amount of time the delay could last without negatively affecting the user. Provide a rationale for each estimate, and include relevant examples and research in your response.
System confirming the user’s password during log-in
Synchronous group editing of a document
Asynchronous critiquing of other participants’ work
Voting on serious issues
Guidelines for Submission: The report should be submitted as a two- to four-page Word document that uses double spacing, 12-point Times New Roman font, one-inch margins, and APA style for any citations.
Explanation / Answer
system confirming the users password during login - 0.5 seconds after entering password and current users expect password confirmation or to prompt that password is incorrect even over a network
synchronous group editing of a document - they express concern over group editing done of anything synchronously and one user has to be in control of the document with others providing inputs and if it is a collaborative editing a document version control must be put into the place and followed and some of the challenges are faced like minimize response time i.e the response time is the time between the user and user control of the document i.e when user type a character and he gets an acknowledgement of an update and the developer must strive to bring response time associated with local actions and latency for remote actions to be minimum and flexible edits and user must have flexibility to edit the document however the technical challenge is to manage multiple streams of concurrent activities so that the system consistency is preserved and it will take time for the user that controls the document editing
asynchronous critiquing of other participants work - these critiques can be collected and sent to the person who controls the document and this is a good situation that preserves any concern about version control and some delay is reasonable as the suggested changes by user are uploaded just as uploading attachments into a email message take some time i.e often seconds
voting on serious issues - the system can gather votes not at a time as they arrive and a short delay is responable as the votes are entered and submitted as the voting results need to be tabulated and broadcasted at a same time otherwise results would vary due to time delay which may prove frustrating if not confusing
