Shefaly blogs about the importance of keeping promises to customers. Drawing largely from the consumer product world, she paints an argument for timely delivery and the serious costs of messing up. In the highly transactional world of consumer goods with large volumes of relatively lower priced goods getting sold to the masses this is very true. You absolutely have to tie in your suppliers, manufacturing, marketing and sales to a tee.

Move to software.

Nick Carr talks of commoditization in the hardware and software product markets: "It's typical when industries mature and buyers start focusing on prices rather than features…. They're competing on cost rather than innovation and features."

What about the world of software services? Firstly, we deal with 'clients' and not 'customers'. Dawud nails the difference. With clients, the 'when' of delivery is important, but the 'how' of delivery is even more important.

When was the last time you had a large, complex program delivered perfectly on time? Let's face it. Slip ups happen. Unlike a P&G shampoo, each project is 'manufactured' to order and there is too much magic in the process for things to be perfect. What saves the day is relationships and the trust that comes with it.

So, how do you build trust while you deliver?

Honesty: Many delivery issues have two sides to it. Both the vendor and the client could have done things different. One way to open up clients to do their bit is by being honest about one's own mistakes. When clients see that they you are your own devil's advocate, they will stop feeling compelled to attack and will instead be open to meet you half way.
Honesty is also in being open about what is good your clients. Say you are trying to sell a rewrite of a large legacy mainframe application. There are two options in front of you.
Option a). Keep the backend as it is and rewrite the UI alone in a new technology. Price: $5M
Option b). Rewrite the whole thing lock stock and barrel.  Price: $12M.
Based on your analysis you are sure that Option b would be too high a risk to take and would likely lead to failure. Option a, though far from ideal would more than meet the needs and has a high chance of success. Which one would you recommend? If you put down the pros and cons in all honesty and recommend option a, this would lead to a high trust partnership and if you land up with downstream issues in delivery, you will have the client on your side. Joe Ippolito has some good tips on honesty in sales.

Communication: Communicate both the good and the not so good at the right time using the right tools. Often, bad news is bottled up and hidden away from the customer until it is too late. The reasons? Hope and fear. On one hand, people hope that somehow the problem would vanish and on the other hand they fear that bringing things out into the open would spoil relationships or make them look incompetent. Often, bad news is brought up through emails. Big mistake. Face to face communication of bad news allows appropriate communication of the context and ensures you have better control on the situation. Communicating bad news early and in a face to face discussion builds trust and shows the client that you really want to solve problems.

Listen, listen and listen: Listening to anyone provides that person psychological air and allows a climate of trust to build. Ask for ways in which your service can be improved and don't take "all is fine" for an answer. All is never fine. Probe to bring out small irritants. Nips these in the bud.

Choose battles wisely: Every client will have shortcomings. Overlook the small ones, complement the client and compensate for these lapses. Letting the small stuff pass builds trust and allows you to bring up the more important aspects where you need the client to change.

How you deliver does matter a lot.

Abhijit writes about estimation as being the weakest link in software development. He says:

"Most of the times the people who estimate and people who develop are different, their skillsets are different, and most importantly the business needs and constraints change at a higher frequency. "

Estimation is surely a weak link. Often, sales guys try to sell the project through an estimate. From a management perspective, if you can get the three edges (scope, time, cost) of the 'golden' triangle to meet then you have a successful development project. What do you think is the weakest link ?
