I would tend to agree with Justin's comments. One suggestion would be to create what I call a 'cafeteria' approach to the problem. Typically, as Justin noted, not all the items in the IEEE standards will apply to your efforts. I would pick out the most pertinent items (your choice of course) and assign risk values to NOT implementing them (opportunity costs). Then factor in the relative costs of implementing the standards.
The opportunity costs are most easily recognized as time. For example, it takes 'X' number of days to perform some task the old way. Implementing this new standard would reduce the time to some 'X - Y'. As we all all know time is money. The time saved might be due to things like streamlining processes or due to reducing defects leaked to the field and the related costs.
What I am talking about is return on investment or ROI. You have to make a convincing argument that implementing these new standards will save the company time and therefore money. Not an easy task.
You might try to pick some low hanging fruit to get things started. Show some success and you might get more cooperation.
Let me know if you'd like some further discussions on this topic.
