When to manufacture it yourself - and when not to
Value-added Services:
How and When to Use Them
By Sandia Harrison, Director of Marketing, FPE Automation
In today's post, let's tackle a question that is arguably one of the most difficult in manufacturing
If Shakespeare were alive today and working in production ops, instead of the famous quote, "To be or not to be," he might ask, "In-house or not in-house?" This, folks, is as close as we come in manufacturing to an "existential question".
What should you produce, and what should you outsource? When is it worthwhile? Are there times when it's a bad idea? And why, throughout the decades, has this remained such a challenging topic?
Let's break it down.
First, why can't you find a clear answer?
Even using the most sophisticated artificial intelligence (AI), you have probably already discovered that you won't find a simple answer online. We are all practically bombarded by webinars, industry publications, and blog posts. Sure, you might come across some very helpful information. However, there are too many variables. One size does not fit all. What works well for another manufacturer might not work at all for you.
You could bring in vendors, consultants, and reps. Maybe you already have. You can schedule appointments, have them stop by, and listen to their pitch. They are probably helpful - to a point. They'll tell you that they can produce sub-widget x for a specific price. You might know how much that item costs you to produce. You might not. It can be tricky to calculate. Or, you might be looking at the wrong sub-widget entirely. It's nearly impossible to tell.
It's an open-ended question with too many valid answers.
Assuming you do know the exact cost for you to manufacture the sub-assembly, and you are confident that it is the ideal spot in your manufacturing process to consider outsourcing, there are still several other factors in play.
- Who can produce the item more optimally? Sometimes, having the parts come off one assembly cell and immediately brought to the next one can help optimize your production. For some, it creates a bottleneck. Be careful not to lose sight of the bigger picture. Your goal is not to outsource. Your goal is to streamline your operations. If it doesn't do so, look elsewhere.
- How specialized is the item? Certain highly specialized items might be a "custom" even for an expert in that particular area. Do the size, design, or other characteristics make it a good fit for outsourcing? If you can purchase an off-the-shelf item that is a drop-in replacement, it will often be your best choice. Protecting your intellectual property is a priority. There are certain items you may not want to outsource to protect trade secrets and avoid sharing confidential design details.
- Are you facing longer production times and other interruptions? If you're short on bandwidth, it can be a lifesaver to outsource an item. On the other hand, it adds an additional layer of delivery and potential delays that someone at your company will need to manage.
- Can you make it better? Or not as well? Quality and consistency are key, of course.
- Factoring in labor costs: Do your employees have the knowledge and time to manufacture them? Will it involve overtime or delay production?
- Do you have the space to store the items? You may be able to roughly calculate how many sub-assemblies you would need on your shelves to get you through a day/week/month/quarter. Do you have the physical space/square footage to both manufacture and store the item until it is ready to use?
- Do you have the equipment and production space? Perhaps you have aging, inefficient machines. When they break down, will it be cost-effective to invest in new ones? If you were to discard, sell, or write off that machinery, could the floor space be used for higher-value processes?
- Transportation costs: If you are able to outsource the items nearby, you may be in luck. If there is no local supplier, it might be very costly to get the goods to you from a distant location.
