Whether you are looking for a job or looking for a customer you have to sell yourself.
What are the benefits and advantages you bring to the buyer?
Why you?
Can you state tangible data?
Unless you can tell them how your product (or yourself) can provide a benefit or advantage rather than just fulfill a need for a feature, then you are just a commodity. There are tonnes and tonnes of commodity products just like you out there. However, when you provide tangible data, they see the benefit.
Example 1.
1. Created a program that automated the analysis of client data increasing productivity and saving money.
or,
2. Developed automation to analyze client performance and opportunities; cutting cycle time from 3 days to 15 minutes and creating the equivalent of two full time analysts.
Statement 1 is generic. Statement 2 shows how I increased productivity and saved money providing the actual benefit.
Example 2.
1. Analyzed modifications to call center sales teams to improve performance and lower costs.
Or
2. Identified over 6 MM dollars (~40% of budget) in improvements to department financial results.
Statement 2 shows the tangible improvement was quite significant while statement 1 leaves it vague.
Whether you are selling yourself or your products, focus on the benefits and the advantages. The features are helpful, but they should be used as stepping stones to educate the potential buyer on how that product (or you) can improve their situation.
