As a Web development and Java consultant, iSeries programmers and managers often ask me: "What is the best way to get started?" This tip offers some advice to project managers and is based on my experience building dozens of production WebSphere applications.
Tip 1: Pick your project
If this is your first project and you don't have experienced assistance, make sure the project is small and manageable. Your team will have to learn Java, HTML, WebSphere, SQL, and JavaScript. Combining this learning curve with the requirements of a large project can result in many issues, such as improper design classes, poor performance and usability issues. It is much better to take your "learning lumps" on a small project rather than a large one where mistakes are much more costly.
You should also make sure that your users will be happy with a browser/HTML-based user interface (UI). Browser interfaces are not as rich as desktop applications, so make sure your users understand that. For example, browser applications typically don't support drag and drop.
Get help if you need it
If you don't have the luxury of picking a small application and need to develop a larger more critical application, you should consider getting help. There are many professional services organizations you can tap for assistance, including the company I work for. Here are some of your choices for heavy-duty Java and WebSphere needs:
[TABLE]Use DICE and Monster
Other useful tools available include Web sites such as www.dice.com and www.monster.com. These sites provide the ease of placing a job posting with specifics on potential employee qualifications and certification. Starting at $305 for 30 days, DICE will post your position to millions of qualified IT personnel. Monster's cost starts at $365 for 60 days with discounts provided for multiple postings. If you don't want to weed through all potential applications or e-mail, you may a

lso buy the rights to view certain resumes instead of posting a job. The cost of this is around $400.
Get help with graphics
AS/400 programmers (including me) often struggle when designing graphical user interfaces. We are skilled in accessing data, concurrency, and business rule validations, not Photoshop and graphics. If you find it difficult making applications look decent check out Elance. This site offers a multitude of illustration, animation, logo creation and many other creative services for those of us who are not so artistic.

Tip 2: Take small steps
After you have secured your resources you should divide your project into small subprojects or "use cases." A "use case" is a functional item that your application performs and is a common term used in object-oriented programming. For the first few use cases, you should go through the whole process of development, deployment and testing. Get the application in front of the users and get their feedback. This does several things for you:
Tip 3: Force documentation and quality control
Most developers hate to document and test. Your application code base can quickly grow in size, and with multiple developers debugging issues becomes more difficult. It is easy for one developer to create a bug that another developer has to spend many hours or days tracking down. The larger the team, the more you should have unit test plans in place and require testing procedures at the unit code basis. You should also have requirements adequately documented. To play devil's advocate, ask yourself what happens if:
You should expect and be ready to handle situations such as those.
Summary
WebSphere application development involves bringing together many resources -- some technical, some personnel. I hope these tips provide "food for thought" as you kick off your projects.
