Do we model ad hoc process tasks in BPM?

The first step in BPM processes is often ad hoc: A customer fills in a request form, an employee reports an issue or a salesperson enters a new sale. You can’t predict when exactly they will occur, but as soon as the task is executed, the business starts working on fulfilling the job. These ad hoc process tasks are an integral part of the business process, or are they not? Different viewpoints Business and IT often tend to disagree at this point. Lets analyse what makes this situation such a problem. What does the business expect from a...

Forms in BPM: the correct way

Posted by on 20:28 in BPM | 1 comment

You know about good BPM design, about separation of long-lived flows and short-lived interactions. You want to move your forms outside of your long-lived flows, preferably in a dedicated GUI product, but the business requires you to put the forms in the BPM flow. Either because they want one system to handle all interaction, they need the persistence in every step of the user-interaction, or maybe because they need the transaction log for legal reasons. How do you solve this dilemma? Where to put user forms in BPM User forms are a good...

Posted by on 13:54 in BPM | Comments Off on The difference between case management and classic BPM

At the start of any large business automation project (after the analysis of the business domain, but before the design starts) you should always ask yourself the question: will I be using case management or classic BPM? This decision has a huge impact on the final result of your BPM project. But what is the difference between case management and classic BPM? And what will be the impact of choosing either solution? Classic BPM Business Process Management originally was a method of analyzing and optimizing the processes in a business, as...

Implementing Cloud Scaling

Posted by on 16:16 in Cloud | Comments Off on Implementing Cloud Scaling

In a previous post, I showcased an example of waste in a customer environment. The customer had two massive servers in a fail-over setup, which resulted in low utilization. The customer was paying for a system that was at best 50% utilized, so 50% of his costs were for the fail-over scenario that may happen once or twice during the lifetime of the servers. To reduce the cost, we can switch to a scalable environment. But how do you achieve a scalable environment? How do you implement cloud scaling? How to imlement cloud scaling The general...

Good BPM process design

Posted by on 21:20 in BPM, SOA | Comments Off on Good BPM process design

People often wonder makes a good BPM process design. Should a process include many small steps, or should it be a few large steps? Do we avoid user actions, or do we make extensive page-flows as part of our process? I find that these things are not what makes a process design good or bad. Good design is mostly about avoiding pitfalls. Here are some tips that will make your BPM processes better. Separation of business data and process state The most important step for good BPM process design is to remove all your business data. You don’t...

Auto-scaling in the cloud

Posted by on 09:22 in Cloud | Comments Off on Auto-scaling in the cloud

Lately I was visiting a customer that was moving its applications to new servers. They had acquired two huge servers to host their middleware solution, connecting their on premise applications and their cloud-hosted solutions. The client went for an active-active setup, where both servers are handling the load, but if one server fails, the remaining server must be able to handle all the trafic. It sounds like a good setup, but it introduces a lot of waste. We will go into this and show why a cloud solution using auto-scaling is so much...
