My company is planning to outsource the development of a J2EE web application. We have invited 7 external consulting firms to bid for the project. Each of the 7 firms will be making a presentation to us in early July. What questions should we ask the firms? (I have 5+ years of Java experience already)
Well, you shouldtest that they do have a good working knowledge of Java and J2EE, particularly around areas such as architecture, performance, scalability, security and so on. If you're outsourcing the project with a view to maintaining it in-house in the future, you should also ask them how they will ensure that the system is as maintainable as possible. Look for use of industry standard techniques along with architectural and design patterns. Don't be afraid to ask how they would go about architecting the solution. Also, check for experience with the environment in which the application will be deployed, as well as experience of the business domain. As well as the technical issues, there are all the others such as quality, testing, documentation (UML vs. other), development methodology, management, etc but I think it's the technical Java/J2EE related issues that you were looking for information on. Hope that helps Simon
Thanks to all who replied. ORIGINAL MESSAGE: [ My company is planning to outsource the development of a J2EE web application. We have invited some external consulting firms to bid for the project. Each of the firms will be making a presentation to us. What questions should we ask the firms? ] REPLIES: -- 1) Who will maintain the app? 2) If the firm is going to maintain it, what happens if their company disappears? Do they leave you with the option of handing maintenance/upgrades/bug fixing responsibilities to someone else? -- Something to ask is what comes with the deal? If you don't have hardware and software to run this app on yet, you may want to pick a vendor that can provide it for free or a reduced cost. For example, IBM usually gives DB2 with WebSphere, and the software comes with a 90-day trial, so you can be up and running before you have to start paying for it. Another thing to remember (not really a question), is that the firm that can do it the fastest and the cheapest and provide all the functionality, is not necessarily the one you want to go with. You do actually get what you pay for. -- What insight will you have into the progress of the project? How will you know if something is going wrong and how soon will you know it? What will your remedies be? What documentation standards does the firms work to? What will be stipulated in the contract? Who will monitor this? What are their testing, verification and validation plans? What will be stipulated in the contract? Who maintains them? What are the costs of requirements changes? How are changes managed? During development? After initial release? Will the source code and documentation be held in escrow? Will you be litigating with a company in bankruptcy just when your customers need a new release? -- Delineate specific J2EE roles--web design, presentation, component provider, et al.--and obtain profiles of who will performing the work in each area, preferably with resumes. Although the cheapest bid is often not the best, some of the more spectacular consulting failures occur at premium prices. One firm much in the news recently had a habit of using lucrative engagements as a training ground for novices. A red flag is raised when you have relatively ordinary requirements and the prospect suggests a speculative technology, e.g. JXTA for an HR web portal. My impression is that established local consultancies are typically competent, reputable and as worthy of consideration as the more familiar national firms. -- [...] in general I'd look at what kind of framework the companies are using for the web application. Most web-side J2EE development these days uses a framework approach (such as Struts), just because it's much faster to develop than an all-custom code approach. You need to be comfortable with the choice of framework in order to maintain the resulting application. -- Well, you should test that they do have a good working knowledge of Java and J2EE, particularly around areas such as architecture, performance, scalability, security and so on. If you're outsourcing the project with a view to maintaining it in-house in the future, you should also ask them how they will ensure that the system is as maintainable as possible. Look for use of industry standard techniques along with architectural and design patterns. Don't be afraid to ask how they would go about architecting the solution.

As well as the technical issues, there are all the others such as quality, testing, documentation (UML vs. other), development methodology, management, etc but I think it's the technical Java/J2EE related issues that you were looking for information on. -- Ask them for reference clients and named referees. Then contact those people..... (Give them advanced notice that you will require these at your presentations...)
Ask to see their coding standards documents. Don't take "Oh we use XXX for an answer "Ask to see the actual documents...
Make them quote for the project AND include two years maintainance. See how they feel about supporting their own code at a fixed price. Put them on penalty clauses if they screw up... --
Ask them "what do you do to make your work high quality?" as described in my note "Nasty Question" at http://www.multicians.org/thvv/nasty.html It's surprising how many teams don't have a good answer to this question. -- Questions to ask: 1. Experience 2. Customers 3. If they test your website for functionality and load 4. Do the developers test or do they have a QA/Software Test Team? 5. Do they guarantee their work? We used a company called ITX and they did a great job, I have contact information if you are interested. -- Ask them which area of the project will present the greatest difficulty. The answer should help in weeding out the idiots who are clueless. -- Ask them what kind of metrics they employ in their process. Ask them whether they can use the Extreme Programming methodology. Ask them whether they will force YOU to write the user documentation to the system BEFORE a single hour of their effort is spent (this is a great way to have a cast-iron requirements spec "in disguise"). Finally, only a sign a fixed-cost contract. --
