System Development Life Cycle

When creating software, hardware, or any kind of product

System Development Life Cycle When creating software, hardware, or any kind of
you will go through several stages, we define these stages in the System Development Life Cycle.

The Cycle
Any System Development Life Cycle it should result in a high

The Cycle Any System Development Life Cycle it should result in a
quality system that meets or exceeds customer expectations.
It must be finished within time and cost limits, works effectively and efficiently and is inexpensive to maintain and cost-effective to improve upon game.

Cycle

As this is called the Systems Development Life Cycle, it's quite usual

Cycle As this is called the Systems Development Life Cycle, it's quite
that a company will then go back to the analysis once it has evaluated a product.
Think about some of the software products that you use, they probably have a version number or a year, and reuse code and designs from previous years

With the Systems Development Life Cycle, you never just quit, you are

With the Systems Development Life Cycle, you never just quit, you are
always looking at ways to improve or surpass what you have created.
Example, Microsoft Flight Simulator…

Systems Development Life Cycle: Analysis

When you are given any problem you should

Systems Development Life Cycle: Analysis When you are given any problem you
start off by finding out about the problem and getting an idea of what you will make to solve the problem by:
A detailed look at current systems
Establish the objectives of the new system

Game Design

Electronic Crafts wants to create a game that will sell successfully,

Game Design Electronic Crafts wants to create a game that will sell
so it needs to see what the market wants to buy and what their current interests are. It will gather data on:
How previous similar products have sold (market data)
What customers are interested in (questionnaires and interviews)
Whether it has any code that could be adapted or reused (internal data)
Feasibility of making any proposed game (is it possible within the time, technical, cost and personnel limits to make the game?)

SMART

Once it has done its research, it will create a document listing

SMART Once it has done its research, it will create a document
objectives for the new system.
These objectives must be SMART so that we can check if the system has been created successfully.

Student Activity Game design

Question 1
Answer :
S - Yes
M - Yes, Yes you could

Student Activity Game design Question 1 Answer : S - Yes M
demonstrate this
A - Yes, this should be possible
R - Yes, this is core to playing the game
T - Yes, this should be achievable within the time given

Question 2

Answer :
S - Yes
M - Yes, Yes you could demonstrate this
A -

Question 2 Answer : S - Yes M - Yes, Yes you
Yes, this should be possible
R - No, this is very unusual, why would they need it? Unless the users specifically ask for it
T - Yes, this should be achievable within the time given

Question 3

Answer :
S - Yes
M - Yes, you could demonstrate this
A - Maybe,

Question 3 Answer : S - Yes M - Yes, you could
this might be possible, but why are you writing your own code, can't you re-use code from a previous version
R - Yes, the game will need graphics
T - No, doing this within a year time limit is too difficult.

S - No', what does 'really, really, really mean? Be more

Question 4 Answer : S - No', what does 'really, really, really
specific, e.g. 80% of test users should rate it outstanding
M - No, see above
A - Maybe, but how do you measure it?
R - Yes, you're aiming to be the best
T - Yes, you're hoping to make a top notch game within the time given
