It's important to remember that this budget is part of a proposal; it is inherently not set in stone, so it does not have to be perfect. You do not have to identify every expense that you will incur during the course of the project, but you need to show that you have considered, identified, and can estimate the major costs of the project. If you don't have ...

It's a massively important question. Short response: apply the concept of encapsulation. Divide into subsystems During development, assign design-ownership (distinct from project manager role, although may coincide in a small group) to subsystems, and to the higher level design Define interfaces (mounting, electrical, thermal, plumbing, material flow, etc) ...

I don't think there is any formal standard way out of this mess. The good news is that at least tracked the changes by serial number. Inventing different models after fact seems pointless because the customers won't know what models they have. From the customer view, these are all one model but vary by serial number. Document it that way. You could ...

I've dealt with this in many ways. Ultimately, here is what I look for when I have to go beyond local sourcing of custom parts: Responsiveness. You can have the best website in the world, but unless I know you are there for me when I need to change anything, I can't rely on you. Questioning. The best vendors I have for custom pieces ask questions and ...

What is Fair? Your definition of fairness is the quantity that you are really trying to optimize (maximize). There can be multiple methods to optimize for this, but first you have to define how this will be calculated. I am going to describe some possible methods below. Maximize Number of Full Orders This method assumes that the happiness of each ...

Tracking the various product versions by serial number is a good idea, but be careful to standardize that as well. Years ago while working for an electronics manufacturer in service and repair, I discovered two units; one was serial number 0024, the other was 00024. They had changed from a four-digit number to a five-digit one and in the process created a ...

I'd go about this in a different way than Trevor. I'd start with a bill of materials and other things you need. Material is obviously the physical stuff, other things means your time and time of others, lab time etc. List all the stuff you know you need and account for the small odds and ends that you can't know for certain, like nuts and bolts. The smaller ...

Waterfall Waterfall is the basic method that a lot of engineering is done with already. I would say that "waterfall" was the original method for software engineering because software engineering came about much later than the other areas of engineering, e.g. software already borrowed from other areas of engineering. Agile (and others) Agile is used ...

It is my observation and practical experience that most engineering product development processors are industry and institution based. Waterfall though old are still used in some industries. But thanks to the software industry and globalization agile methodology is fast gaining acceptance is engineering discipline. The automotive industry is one that has had ...

First, a big (100 or 1000 engineers) project is very unlikely to start from a blank piece of paper. A company like Boeing has designed many planes in the past, and therefore has a pretty good idea how to "guess" an initial design for a new one. One method that works is to start from an initial "guessed" design and refine it. Given the ...

Your question is a fundamental problem and does not have a single way to be handled. IMHO it boils down to the management of engineers and designers and is fundamental to the success of a company. IMHO (it might be very simplistic compared to what Jonathan R. Swift might have to offer, since I've only worked in a small company with less than 20 engineers ...

At very highly level the three areas that need to manage are scope, cost and time also known as the triple constraints. Scope: Make sure the sponsor clearly defined the project. It is highly unlikely that the sponsor will document the scope. Therefore you need to document the scope and get some type of agreement from the sponsor. An e-mail might be a good ...

I think this depends on how much information you want, and how formally you want to track it. It sounds like currently, none of this information is written down anywhere, which is obviously the first problem. But putting down information for a solution that you don't intend to pursue is, at best, a less-than-optimal use of time. You'll have to define which ...

The main purpose of a ECO process is to communicate changes to team members, other departments, customer and suppliers. ECO is industry accepted process that has now been automated using various tools. All affected parties need to provide input for the system to work effectively. Many global organization require multiple levels of approvals. In one such ...

The formal way to avoid such situation is called configuration management. Even with such a formal process there are occasions that engineering run into such scenarios. One of the most recent is the Takata Air Bag Recall. Therefore there are plenty of examples to handle such scenarios, but one size doesn't fit all. Following are few suggestions to address ...

History tends to teach us that attempting to design something without having a clear idea of what you ultimately want to achieve rarely works out well. Equally the definition of the problem to be solved should address the underlying problem, not just be an outline of a proposed solution. There is, of course, a perfectly valid place for open-ended or ...

Software engineering is a relatively newer form of engineering so borrows more than leads - the agile methodologies borrowed heavily from lean manufacturing, Toyota and Kanban. The Wiki summary of Toyota principles is very close to the agile manifesto.

First, do away with "one for everyone" as the primary ones will be left with empty stock and the marginal ones with unsold ones. Distribute according to your "Same Percentage of All of the Orders" method, rounding it down; assigning maybe 95% of the number you'd be able to assign. Then dispatch the remaining units to stores that issue individual requests, ...

At higher volumes, these weight plates are generally cast iron. Here's a link to some more info on that: http://www.metals-china.com/cast-iron-weight-plate-iron-casting-foundry.html . You'll want to search for "cast iron manufacturer." Adding the country to the end of that search term will help you find someone based on location. Note: Generally, it may be ...

I would like to add a bit to the two answers above. More of a practical explanation of your CAD question. Latest CAD, CAM and CAE software allow multi-user simultaneous work by using referenced models. That is, as you mentioned the assembly with part A and part B. There's an assembly model that references (links) the models of the two parts. Also while ...

The critical path is: "the longest path of planned activities [...] to the end of the project" Wikipedia In what I would call "purely theoretical" Critical Path Analysis, the length of the project is the length of the critical path. Therefore tasks on the critical path have no slack by definition. In the real world there may be external dates setting ...

Requirements come in 2 flavours, client requirements and technical requirements. Client requirements are converted to technical requirements because they are usually too abstract to be used as absolute metrics. For example, the client might say "light," but your technical goal is something more tangible like "0.5 kg or less." It is important to understand ...

Why do you need a spring? Have a vertical tube with a gentle curve to feed the balls and all you need is a small pin to stop the balls getting to the drive mechanism. The mass of the balls will autofeed... Or you can make a "gate" to allow one at a time... Perhaps think of a pinball machine. So, how about two pins which need to be linked together. ...

In context of the question, the goal is to engineer a product to maximize the return on investments (ROI). In order to achieve this one has to engineer the product meet Voice of the Consumer/Customer (VOC) which essentially is the requirements. The hardest part is to understand VOC, or "What is the problem consumers are seeking a solution?". There is no ...

I have been in engineering management and planning capacities several times in my career. The purpose of planning is to match what you want to achieve with the resources it's going to take to get it done. I've seen many examples where failure to adequately consider resources caused projects to fail. Which results in a lot of discouragement for both the ...

You hinted at the answer in your original question - Pack and Go. If this were my project, I would create a 'Package Master' top level assembly that contains your 40 assembly files as sub-assemblies. No need to mate them to each other, just have them there contained within the file. Then use the Pack and Go feature that you're familiar with. I always use ...

Most operating systems can substitute the path so that after the operation another path looks like another. So from the softwares perspective it is the same path even if it is not. This is a very easy way out as you dont need to change anything at all. How you do this depends a bit how your computer/network is set up. This said solidworks includes a tool ...

I would make a copy onto a USB stick then, at best, check that on a separate computer - any broken links should show up. If you don't have separate computer then a new account may do the same - as long as it does not get access to your user file directory.

The amount of information you specified is too limited. If you had more information, maybe you could do it, but not as stated. Machining tasks can vary greatly. I can imagine some parts where it might literally take hours to get work piece fixtured in the machine, but then the actual machining operation takes only a few minutes (e.g. a giant part for a ship ...

No, because the number to be produced changes the percentage ie the setting up time can be longer than the machining time for 1 piece but 3% for 100 pieces and 0.003% for 1000 pieces...
