A few questions. (1 Viewer)

1 )
I know this is a trivial question, but the SDD syllabus is picky and stupid, so meh.
Do the programmers actually partake in the 'planning' stage? I mean I thought they plan algorithms during that stage? Some sources disagree there.

2)
Also, can someone explain to me what boundaries are in the context of defining the problem? the way I see it is that if you're a programmer making a piece of software with a team, the boundary is the point at which it is agreed that they'll take it so far. In other words, how explicit they choose to get defines the boundary...or DOES IT?

3)
If you're outsourcing a program, who does the feasiblity study? In general though, who does? Is it the management of the organisation, or just the analysts or who?

it depends on the project..

If the project is process and maths oriented then the logic of it are prolly planned and written b4 hand (not psudo code tho).

but if its a system development..its highly unlikely..

boundary just means drawing line on what will be done by ur program.
eg. You would probably say your video ezy system has boundary of just organising the videos, rentings, returns, customer dbs etc. So your system would not have have money related functions. If u don't have boundary ur system becomes uncontrollably large. does this make sense?

feasibility study is a thing system analyst carry out. It examines whether building the system is doable or not. There are many critirias and they are operational, technical,, financial and time.

if you plan to make a system that organises the names of everyone in the world..u have to see if its technically feasible.. do u have good enuf hardware to process all names? etc etc

HTH

Yeah, thanks.

I'm not in year 12, I just went through the first few chapters before next week, where year 12 actually starts for me.

And so a boundary is sort of like the scope of the new system, yes?

As for the rest, I think I'm okay with it.

 

[iptteacherssuck]

yes

Boundaries are also the borders between systems, eg. Like the classic Train-system and Station-Platform-system. The data passed between the two are the passengers getting on and off the train.

Correct me, anybody, if I'm wrong. I haven't studied SDD for a year... #

 

[CHUDYMASTER]

Yeah

That's what it says in the book anyway. Although I was thinking of how it was used in defining the problem of the current system.
