Software Development Top 30 Mistakes

Software Development Top 30 Mistakes

 

I have been developing software and web applications for nearly 11 years now.  Software development has come a long way since the days of Binary, Cobol, etc.  What still fascinates me about software development is the same mistakes made before, are still made today.  Below are the top 30 Mistakes that are made within the software development process.  It's amazing to see that none of these have anything to do with the language itself.

 

1. Not understanding the user's needs. Lack of user input, or not even asking.
   没有理解用户的需求.缺乏用户支持,甚至连问都不问.
2. Underestimating the size of the project.
   低估了工程的大小.
3. Rushing through the planning stage, or avoiding the planning all together.  Code first, plan later! BAD!
   直接跳过计划阶段,或是逃避同大家一起做计划.先编码,后计划.太糟.
4. Not testing early enough, often, or at all!  Make it a habit!
   往往,甚至一直没有尽可能早地做测试,要养成习惯啊.
5. Choosing the "Cool" methodology at the time, vs. one that has worked in the past. Which leads into my next point...
   选择使用当时很酷的方法论的人和那些过去工作了的人.谁将指引我到下一步
6. Not using a methodology.
   没有使用方法论.
7. Letting a software developer run the software development project.
   让一个软件开发人员制定软件开发计划
8. Bored, unmotivated team!  You have to motivate your developers!  If you can't motivate, don't bother trying to lead.  Your team will fall asleep, literally.
   枯燥无激情的团队.你必须引起你的组员的兴趣.如果你无法做到,就不用为做领队而烦恼了.你的队伍最终会睡倒一片
9. Planning on catching up later.  You won't... don't even think it!
   计划赶不上变化.这点连想都不用想
10. Non Source Control!  Ouch.. not good people... and no, just installing a software package is not it...
    不控制源代码.噢,真不是好人,而且不要只是安装一个不属于它的软件包
11. Deciding to switch your development tools when you’re already into the project.
12. Allowing feature creep.  Just say NO!  Everyone will be happier in the end.
13. Omitting necessary tasks to shorten the project plan.  Really, what's the point of doing this?
14. Insufficient management controls in the development project.
15. Lack of high level business sponsorship.
16. Adding people at the end of the project to "speed things up".  You will only slow things down...
17. No unit testing.  Heck if you can do it, use Visual Studio Team Foundation Server and set up some automated testing nightly.
18. Stressed out software developers.  If you have managed to perform even one or two of these software development mistakes, you will have a stressed out bunch of programmers to deal with!
19. Lack of error handling.
20. "Off by one" errors.  These happen a lot during the software development process.. *sigh*.
21. Typos...  Just use option strict and explicit please..  during one software development project, which I was on as a consultant, they were getting ridiculous amounts of errors everywhere... turned out the developer couldn't spell and would declare variables with incorrect spelling.. no big deal, until you use the correct spelling when you're assigning a value to it...  and  you had option explicit off.  Ouch to them...
22. No understand the deployment or hardware the software is to be installed on.  Ohhhh it's for a Macintosh... lol.  Well hopefully not that bad, but you get the point.
23. No naming style or code conventions.  Honestly it doesn't matter what you use... as long as you are consistent with the rest of the team, and hopefully at least yourself.
24. Using global variables everywhere.  These are NOT your friend and hog memory like nothing you have ever seen before!
25. Not asking for help at all during the software development process.  If you’re stuck, don't fight with it for hours on end!  Ask for help!
26. Not commenting your code.
27. Hogging all information to yourself.  You think you're more valuable this way?  You're actually not and there is a plan brewing to get you kicked off the development project, and possibly out of the company.  You might want to brush up your sign "Will code for pizza!". 
28. Performing database operations at the application layer instead of the database layer. Not only is this putting the processing juice on your application instead of your server, but you have put your database at risk of data integrity issues, and getting bad data!  Some of my hipster cool friends are always saying "It's alllll good", well, if your database can be caught saying this... and If everything looks good to your database, then you should be worried.  It is NOT all good!
29. Not validating your data! Yikes...  Yes.. let’s just assume all the data is perfect! NOT!
30. No load testing.  What.. This is supposed to run on 1,000 user's machines through Citrix?  Interesting... Shouldn't be an issue! lol... NOT.

Software development is tricky enough!  Make it easier on yourself by ensuring you do not make any of these mistakes.  Although it seems like a simple list of things not to do, it can make your life so much easier! By the way, while you're here, check out our competition to win a free iPod, we are trying to get a software development blog as the number 1 site on Technorati!  All you have to do is add this blog as a favorite, and we will pick a winner as soon as we are number 1! Wouldn't it be cool if the number 1 Technorati Blog was a software development blog with real content instead of "Boing Boing", or "How To Make Money Online"?
