Those which are part of the problem, and those which are part of the implementation of the solution. Let's look at an example to illustrate what is meant by this.
If we are going to make a simple calculator then the processes of addition, subtraction, multiplication and division would be processes which are part of the problem. They are defined before we even start considering the solution. How we decide to manage a history of calculations performed, eg. It is something we think about when planning how we are going to build the calculator.
Any process may be explored through an IPO table but if we say that it's purpose is to help us better understand and define the problem then this gives us guidance as to which processes would be better to model. Ideally we want to model processes representing the problem. Processes which are part of implementing the solution are generally better explained using algorithms. If we are modelling a problem for which a computerised solution is to be created then major processes and things involving calculations should be modelled.
Other aspects of the problem may be modelled considering how important they are to understanding the underlying principle of the problem. If we are modelling an existing system from which to create a new or improved system then we probably want to model more processes within the system virtually all processing is part of the problem but still take into account the comments in the previous paragraph.
Deciding if a process is part of the problem or solution can sometimes be tricky, especially for certain types of things such as games. An easy way to help you decide is to think about what would happen if you were to implement a paper based solution instead of a computerised one. If the process would still be done with pen and paper it is probably something valuable to express in an IPO table. As an example of this, lets consider a game of Tic Tac Toe.
Even if playing the game on paper the process of determining if someone has won the game is still required. This is something we should therefore model. Other processes however such as how the players will input where their pieces are to go or how we go about rendering the board on the screen are processes which we wouldn't consider when playing with pen and paper so they are not part of the problem.
Don't worry that you are not modelling all of the system. You will probably only model a small and fragmented aspect of the system through the IPO diagrams. This is ok. Each diagram, table or chart, IPO's included, is only intended to model a certain aspect of the problem or solution. For example an input may be listed as player wins game. This is incorrect as it is not an input but an event that occurs which triggers the processing.
In an IPO we are not concerned with what triggers the processing that will be looked at in other diagrams.
We are only concerned with what information How To Make A Framework 40 is to be created and what data is required in order to do this.
Maybe the processing involves calculating a final score once the player has finished the game. The inputs then will be whatever details are required in order to calculate this high score. This may be for instance, player health, time taken, bonuses collected etc. Instead of:. Which is incorrect. The input is an action.
The output does have data within it but it is more about how the data is displayed. We only want the data listed in an IPO table. How it is to be displayed is something which should be modelled using prototypes or screen designs.
The processing also involves actions which will be performed but are not actually part of producing the output. A more correct IPO would be:. Your inputs and outputs should be categorised as either a data type integer, float, string, boolean or data structure arrays or records or a file with data in it.
So how do Input Process Output tables fit into the big picture of software design and development? IPO tables are a valuable tool to help you define and understand the problem. This may be one for which a computerised solution is to be created. Alternatively it may be an existing system which is to be replaced or improved.
IPO tables will help you identify and understand the major processes that exist or need to exist. IPO tables look at these processes in isolation. These processes can then be linked together, by looking for matches between the inputs of a process and the corresponding outputs of other processes which will be represented by way of Data Flow Diagrams.
The details of these tables will also help when creating algorithms for the final solution. Pick a sport and create a set of IPO tables that would be required if you were going to develop a piece of software to manage scoring for a game.
Education is the kindling of a flame, not the filling of a vessel. Contact Disclaimer. Input Process Output!
Input The beginning of a rule. They appear literally as they are. Quotes are put around characters which are part of EBNF. Output Alternative items. Data not actions Make sure your inputs and outputs are data and not actions. Also make sure that your processing is purely related to turning those inputs into the required outputs. The right processes Don't start designing your solution through IPO tables.
Make sure you are only analysing the describing the problem. Non technical language Don't use pseudocode or too technical language within the processing column.
