Architectures: Good, Bad and Ugly

Four months ago I attended a conference, where I had a chance to listen to Miha Kralj, an architect at Microsoft, talk about architectures. It was one of the best presentations I ever attended, and ever since I had this topic in queue, but never really had chance to write about it. Most of the stuff he talked about reminded me of some bad experiences about architectures on projects I’ve worked on. Most of stuff here is also not my original contribution to the universal pool of knowledge, and I reuse it with the permission of the author, so Miha, thanks! What I did, however, is that I applied general principles to specific Microsoft Dynamics NAV situations.

Not-so-elementary costing: The Change

They say the only constant is change. I’d say that the only other constant is error. We humans tend to err. Give a repeatable task to a human, and they’ll mess it up every once in a while. Some call it the human factor.

One of the many repeatable tasks in Microsoft Dynamics NAV is setting up items. If you remember my rant about mandatory fields, and how I said they were baaad, there might be an even more baaad kind of fields: the default value fields. Because the system simply inserts a value into these fields without asking for your say, and if anything is easy, it’s only so easy to overlook these. Yep, you have a chance to voice your oppinion on these, but having got to hurry for a cup of coffe with Mary from accounting, admit it, you’re gonna leave that default FIFO costing method for an item every once in a while, even though it should really have been Average. Then you’ll start posting. Then your phone rings and starts screaming at you about a moron who screwed up items again.

Manufacturing quickie

Today, I got an e-mail from a reader of this blog, who asked me to help them with an actual problem on a project. Their customer is a small manufacturing customer in textile vertical. Whenever they calculate consumption, quantities for certain items get rounded to full numbers. Since the items are usually textile, measured in meters, a consumption of 1.27 meters can end up registered as 2 meters instead. Not that it’s something which can’t be overridden manually, but it is pain in the butt, and hey, why do we have computers in the first place if we have to do their job.
