In any work environment there are always circumstances that are a little less than perfect. However, if your job is not completely awful, then there is still potential. You just have to alter your environment enough to make it closer to your desires.
Some people have the pessimistic view that they are simply peons; it is all beyond their control. They must live with things the way they are. The truth however, is that each one of us has a huge influence over our own working environment, whether or not we really understand it. For this entry I want to examine some of the things that software developers can and should effect in their work places. We get out of our work what we put into it. Positive changes make work easier and make you feel better about the time you spend working.
Obviously, if you not the boss you can't just leap out and make huge sweeping changes. That doesn't mean you won't have any effect, it just happens slowly. Patience and perseverance are necessary. Continually making gradual small changes is the key to success. We always need to pick our battles very carefully, fixing each problem one by one. Nothing changes if you give up, accept the problems and then live with them. All your potential goes into reinforcing the status quo instead of improving it.
Wherever I go, I always start with trying to correct those problems that are closest to me. I like to start nearby and work my way out; getting the simple things fixed quickly, then gradually tackle larger and larger issues. This keeps up a positive momentum of successful changes.
For any rogue software development environments, the first big problem usually encountered is missing or poor source code control. Given the number of good software packages available for handling this, it is still a surprise to see development shops that don't use anything. Honestly, if you are not using any source code control, you are not seriously programming; you're just playing around. It's not an optional tool. It's not a pain. It always pays for itself.
This issue is much closer to home than actually designing or coding. Chaos with handling source code is far worse than bad source code. Fix this first or pay heavily for it later.
Set up a working scheme that protects the code, makes it easy to build and handles any secondary issues like sharing one code base for multiple instances. For complex projects expect a complex setup. In some cases the source code control software already exists but is being used poorly. Clean it up; fix any of the control problems. For very large teams using several hierarchical pools at different levels may be the best solution. You should be getting stability, reliability and traceability from your setup, anything less should be fixed.
The next most significant problem with most development is automating the build, release and update procedures. Depending on the length of each iteration in the project, manual procedures can be very expensive. Too much time is wasted and the results are inconsistent. Generally these days an IDE like NetBeans or Eclipse or a tool like Ant or Maven make automating the build procedure simple and painless, but few developers move on to the other two major automations.
Packaging for releases and upgrading are big issues, which should be fully automated to make sure there are no silly problems slipping in at the last moment. Inconsistent releases are embarrassing. For clients updating their systems, nothing looks worse than a long series of hard to follow instructions; more than one step is too many.
One-button releases that give the users one-button upgrades are the gold-standard of a development project. They are always possible, but few people invest enough effort to get there, choosing instead to waste more of their time in dealing with manual inconsistencies. You sleep far better at night if there is less to worry about, and messing up the final bits in a manual release is a frequent enough problem. You just need to get beyond your fear of spending too much time on this type of automation, it does prove itself to be worth it in the end. At minimum, for each release, allocate a fix amount of time -- say two weeks -- to trying to automate the big three processes. Gradually, you'll get it working, but even if its only at 80% it still pays off nicely.
Moving out a little bit, we often find in most development positions that we get responsibility for a previously existing part of the system. This 'legacy' problem is a pain, but it doesn't have to be horrible. A great way to learn the code and fix it at the same time is to apply a series of non-destructive refactorings to it. Generally, one wants to compress the code somewhat, but also handle the functionality in the most consistent manner. If you find that there are three ways in the code to handle something, harmonize on one. Fixing the consistency is necessary, breeds familiarity and will save lots of pain later. Updating the comments is another way to get through the code, making positive but non-destructive changes.
The worse part of any development job is flailing away at bad code; no matter who authored it. So it is important to make sure that all of the code you can change is simple, clean, consistent and readable and that any notes on understanding, fixing or extending it are are self-contained. The time we put into code formatting is minimal compared to the time we spend agonizing over problems. The two balance each other out; you'll always do less debugging if you start with better initial code. This is always true; for any system; for any type of code. Debugging is a very important skill to have, but it is something to be avoided wherever possible because it is very time consuming with little payoff.
If you've managed to get your environment under control, your code is clean and it is working reasonable well, then it is time to move on to the system as a whole.
If your project is large enough, there are several developers, some of whom are having problems with their own development pieces. Assisting another developer without getting in their way is a very tricky skill, but another one worth learning. Most development problems stem from sloppiness, so if they are having trouble with their logic the likely culprit is messy code. The most basic help is to gently convince them that a little more discipline goes a long way. Clean it up first, then debug it. Generally this is more of a problem for younger less experienced developers and high-stress environments.
Sometimes the problems come from trying to build something sophisticated without fully understanding the underlying model enough. We often have to jump into development years before we fully grasp the problem, but once the code is set -- even if it is obviously broken -- it becomes hard for most developers to admit their initial approach was flawed. They would rather struggle through with bad code than toss it and start over again. In a complex problem, if you don't have a simple clean abstraction, any amount of artificial structural fiddling will obscure the base structure, making it very hard to fix. Most developers will err to the side of making their implementations more complex than necessary. All of the extra 'if' and 'for' statements cloud the code and make it unstable. It is like stuffing hay into a sack with lots of holes; as you stuff it in one side, it falls out the other. It never ends. Refactoring could work, but only if it goes deep enough to really change the model. A clean rewrite of only the 'core' code is usually the best answer.
When sloppiness or overcomplexity aren't the main problems, overloading variables with several independent values is also very common. Splitting the information into two or more separate variables generally leads to a working solution. Its a relativity painless refactoring, which should be a standard skill for all programmers because overloading the meaning of their variables is such a common problem.
For any of these programming issues, the best assistance comes from getting the other programmer to use you as a sounding board for their code. As they try to explain how it works to you, they often see the error of their ways and how they should correct it. Expressing the solution verbally is a powerful tool. That, consistency, debugging and refactoring are the absolutely required skills for any good developer.
Looking further outwards at the bigger picture, we draw 'lines' in the code by breaking off the dependencies between the pieces; separating them into independent sections of code. If there is a clearly defined 'interface' that one piece uses to access the other piece, then there is a line between them. A system with few or no lines at all is a huge mess, usually referred to as a big ball of mud.
Balls of mud are a common reason that most large corporate in-house systems fail to work properly. 250,000 lines of code with no structure is a nightmare waiting to be deleted. Not to worry, one can add architecture after-the-fact, although it is more work than getting it right initially. The general idea is to draw enough lines in the system, partitioning the code into horizontal and vertical pieces. Breaking the program down into processes, threads, modules, libraries, components, sections, layers, levels, etc. draws important features into the architecture. The more pieces you have -- if they are not too small, and encapsulated within reason -- the better the architecture. When you can easily explain how the system works to another developer in a simple white board diagram in 5 minutes with a couple of diagrams, then you've probably drawn enough lines into the code to be useful.
Another reason to draw lines in your code is to swap out bad algorithms. If you know the code is doing something poorly, refactor it so that the whole algorithm is contained together in a single component or layer. Once you've isolated it, you can upgrade to a newer version with a better algorithm. Beyond the time for the work that is involved, it is boring yet not hard to do. But you need to pick your target selectively or you'll spend too much time refactoring code without enough effect. As an example, switching from coarse-grained locking to fine-grain locking in a web system, means burying all of the lock calls behind an API, then harmonizing the API arguments, then just swapping it out with a newer locking version. All of the related code needs to take and release locks, what happens underneath should be encapsulated away from the caller.
As a complete produce or tool, most systems are seriously in need of consistency and good graphic design. Consistency you can do yourself, and its always worth the effort. Your users will definitely notice and usually if you have contact with them, they will thank you. Hiring a graphic designer and an editor always pay for themselves in terms of the final appearance of the system. Too many software developers think their own poorly designed systems actually look good; users don't complain because it is not worth the effort and they doubt it will ever get fixed; so why waste the time.
If you've gotten this far in changing your working environment, the system is pretty good, so we can move on to bigger issues. This time we go to the users.
We build tools for our users. Our overall direction of the development is to build better tools. This means increasing your 'real' knowledge of the problem domain. Programmers always think they know more than they actually do, so being wary of this will lead you to start spending more time with the end-users to understand what they are actually trying to accomplish with their tools. Keep in mind that we may understand the type and frequency of the data, but that doesn't mean we really understand the problem. Complains are especially important because they highlight some part of the system that needs to be fixed. Rarely are the users actually wrong, it is the system that is stiff and hard to us. It is likely that you could find some tool that better fits the user's needs if you search harder enough for it. Just don't fall into the trap of completely trusting the user's own analysis of their own needs. They know what they want to do -- they are the experts on that -- but they don't really don't know which tools would best suit them, that should be your expertize.
If we come to understand how to build our system for the user, the next step is to branch out into creating more tools that solve their problems. There is an endless degree of trying to compact more and more advanced functionality into an underlying system without actually denigrating it. Too often the professional products 'arc' in their features, reaching a point where successive releases are actually worse than the their predecessors. It is a very complex problem to combine several tools together under the same 'roof' in a way that actually improves the functionality; just smashing them together is weak. Given that so many of our tools are stuck in silos, with poor ways to interact with each other, this is a huge problem in the industry that needs to be solved. Too much time is wasted by importing and exporting data through various different silos, when the computer as a tool is powerful enough to handle all of this for us transparently.
Building your own code is fun when you start, but as you've been developing longer and longer the real challenge comes from trying to direct larger and larger groups to build bigger systems. Bigger tools demand bigger teams. Three guys building a system is a very different arrangement problem than trying to do it with two hundred. Honestly, I know of no large shops of programmers that actually produce great or good works. Small teams craft the initial versions, then large teams slowly grind the code base into uselessness. Even if they have good people, a large team bends towards fugly code. We don't currently have any other methodologies or processes to get around this; it is another huge open problem in software development.
If there are many development efforts on-going, then trying to change them from giant brute-force exercises in re-writing the same code hundreds of times, into a leveragable abstract foundation for building a large series of complex tools is both a technical problem and a personal management problem. Technological issues are fun because they are isolated, but the really challenging problems come from mixing humans and technology; whether it is running the system or just building it. Master this and you've really mastered software development; just knowing how to whack out a couple of 'for' loops doesn't count.
That's enough of a general direction to get anyone from a simple development project into a grand plan to re-develop all of the companies software projects. As you can see, there is an awful lot of simple things that we can do to effect our environment and make it better. Patience is necessary, but we can all do it. You can make enough small changes so that work is is interesting, challenging, but not frustrating. Although it seems contradictory to what many of those evil management consultants are implying, work can be fun, rewarding and you'll actually get more done for your company. A positive workplace is always more effective.
