How many times have you heard "I have an easy request for you..." from either users or the non-technical manager with no concept of what it takes to create an integrated software application?  Most of us that have been up and down the development block have experienced this I'm sure, and also...

Time for Application Re-Design?

Application design, Software maintenance

As an independent custom application software developer I have determined that any really active application (...defined as an application basically designed and developed on an on-going basis, changed and updated frequently as business needs develop) periodically requires that the developer step...

Regardless of the reason for a development project being delayed, coming back to a project which has been "on the back burner" for a while seems always to raise questions about the project.  For me the questions may start out with "Where was I on this before I had to leave it?", to "Why on earth...

My previous post made reference once again to the human interface design of an application and application speed considerations. As a follow-up to that post, I find myself thinking once again about a few of the issues which I have previously posted about code maintenance and new design. "

Updates that Fail

Don't you hate it when an update fails? I had the experience just yesterday while doing an update on my Microsoft Vista laptop.

What keeps an out-of-date application in place

I had the opportunity recently to make some minor changes to reports originally created in the late 80's. The application is a character-based app running on an "old" version of SCO Unix, and hardware that has been kept alive by some clever mix and match combination of "old" components taken from...

We all know what it means to assume -- but sometimes our assumptions are so completely hidden from us that we don't even know when we are assuming. I had an iinteresting conversation with another developer last week that illustrates this point (...and a few others that I've blogged about...

While there is no shortage of writing available on the internet or in software development textbooks regarding the various software development methodologies available, I find that the great majority of it is really geared toward managing large projects for large companies.  Since I develop for...

Application Code Maintenance vs Re-Creation



Posted by: SJC
Business Application Value, Software application development, Software maintenance, Software Quality
