Types of scheduling software
|
|
|
There are two types of scheduling software. One is cutomized product, and the other is package products.
|
|
|
Customized products are able to adapt to customers requests throughout the development and imlementation process. However, it is often difficult to clarify all the necessity at the beginning of the development and, in many cases they are found later and users incurrs extra expenses for additional customization. Users are unable to know whether the software satisfies their needs or not until the end of the development. Generally speaking it takes long to develop and introduce the product. Because of their uncertainity, some risks are unavoidable for those customized products.

On the contrary, package products have a lot of advantageous points. Specifications are clearly confirmed before purchasing, and they are usually inexpensive than customized ones, and through version upgrades users are always able to use up-to-date products and finally, setting up after installation is smooth and quick. Consequently, the risk of introduction of scheculing software will be fairy low.

With the advancement of IT technology, customized products which used to be sold mostly are steadily decreasing in the market and instead, package products are emerging from the view point of cost, implementation risk and so on.

Requirements for scheduling software
|
|
Here, I focus on package products.
Since planning and scheduling packages in the market differ very much from each other in functions, logics, and many points even if they are seemingly the similar programs. The selection should be careful enough to avoid a bad investiment.

There are four important points to be required for good scheduling software as follows.
|
|
|
|
|
|
 |
Capacity for making practical plans@ |
|
|
|
|
|
Automatic planning itself is simple with use of computers. However, results ought to be accurate and feasible enough.
If the scheduler lacks functionality and fails in bringing about a useful result, managers will be disappointed with those impractical plans. They are meaningless however automatically schedules might be created. Please note that , in order to make an accurate and practical plan, functions to deal with planners knowhow are very important. Again, this point is so important that introduction without it is meaningless. Please refer to the other section, 'Importance of schedulers', for more detail. From now on, I'd like to show you the point of selection, supposing that the scheduler is able to make practical plans
