Should I have a Parallel?

Should I have a Parallel?

Alfredo Velasco – May 11, 2015

This is a question that many companies make us, driven by the IT staff that shares their opinion, or because they have heard that in other companies when they have changed their systems, they do not suspend the operation of the system that is going to be replaced, using it in Parallel with the new system, just in case, the new one fails.


In DynaWare, as part of our implementation methodology, we inform to the customers before initiating the project, that we will no handle any Parallel. Frequently we remind this fact during the preparation phase for the operating launch.

The reasons are the following:

When the customer personal knows that they can have a Parallel at the time of the operations launch with DynaWare, in their subconscious mind it keeps registered that they will have an emergency back up in case something goes wrong, so this possible situation goes down in terms of importance to a lower level in their mind, having as a consequence that when a functionality test is made prior to launch, the staff is not fully concentrated in reviewing it with detail because if something goes wrong, nothing will happen, the older system will still be working.

Enhancing processes is part of the transformation of the customer to become in a highly effective company, as this is the objective pursued by DynaWare. And as a consequence of this, the moments of the registries may be different (in DynaWare the registry is made when the event happens, to reflect reality at any time).

Having the Parallel may lead to work extra hours, exhaustion & higher stress within customer’s staff, confusion between systems, and comparisons between them, making this process harder. Sometimes it is mentioned that more than a double effort, because the activity of comparing information that is generated by the two systems, may require a lot of time specially due to the forms that each system uses to present the information.

In addition, if for any reason the user does not has the time to make the double entry, he will give preference to the first system, because is the current system, neglecting the new one and being this, one of the reasons that may cause the start up to fail.

When the Parallel is used, is easier to delay the startup, nevertheless, in the mind of the staff they can think that the launch of the new system failed, despite that the real issue was using the Parallel. Taking out that idea from the staff, will take a lot of work. This is another reason of why not using the Parallel.

Having the Parallel, sends a negative subliminal message to the staff, on the sense that the management of the company does not rely to release the older system, because they have some doubts that the new one will work.

On the other hand, the message that is send to the employees is positive, not because they think is the last chance they have and they will have to figure it out how to handle it, instead they know the company has confidence on the new system, because previously it has been tested.

On the implementation methodology of DynaWare, it is forecasted that on the phase prior to the launch, that integral tests are made with the company data, ensuring that users are convinced that the system works correctly during all the operative cycle and that this reflects correctly on their accounting.

Before launching, there should be a message from the General Direction to all the employees announcing the date when the older system will be unplugged, to start operations with the new one, making emphasis that he counts on the support of all of them to have a successful launch.

Then the attention of the users will be at 100% with the startup of the new system, with the confidence that it works.

The startup of a new system in a company, if it is well organized, it becomes such an important event for all the company that it will attract the attention of all employees. The benefits that this new system will bring professionally to their area and thanks to the new processes adopted, they are contributing to a better performance of other areas and to the company success and their own.
