I'm really keen to do some formal data literacy training - but I'm not sure what I should say to convince him that it's a worthwhile investment for the business.
Does anyone have tips on how I can prepare for this conversation?
I'd start with the business benefit. You have to sell it to him or her in terms that person can understand. How will this training benefit them and or the business-at-large. Get that conversation in place, and the training should be an easy sell. :)
I agree 100% with the earlier comments about needing to be clear on the benefits to the business - but I also believe the best way to seek the investment of others is to demonstrate that you’re also investing in yourself. It doesn’t have to be a monetary investment: think about enrolling in some free, online training modules - or subscribing to data literacy podcasts and newsletters.
Show your manager that you’re serious, that you can apply some of the learnings you’ve picked up through your own development - look for opportunities to learn “on the job” from someone who is more familiar or more comfortable with data - your enthusiasm and commitment to your own personal development will go a long way!
