Canada’s standard of living is falling behind rest of developed world

Even better, you can include customers through interviews and prototype testing. Together, they build up the shared understanding and can all support the written product specification at the end. The aim of a product specification document is to ensure that everyone involved in the product development process understands what is required and that the end product meets the customer’s needs and expectations. Before writing a single scrap of code, a wise software engineer will always write a technical specification, also known as a tech spec.

At Specright, we like to say, “If you get the spec right, the rest follows.” But don’t just take our word for it. Hear from our customers on the value they’re achieving from a spec-first approach. “Now it takes me longer to draft an email to my co-manufacturers than it does to actually run a report and export the quality data to send them. Before you start on any endeavor with your product, you need to go through a discovery process. This process can be done in hours or weeks — regardless of the scope, it is the foundation of the alignment you seek.

The Rise of Specification Management

For example, if you want to use biometric security for user login, here is where you explain why it is the best approach and how you plan to execute it. Now you need to establish what is not possible for the development of your app. This is called the “out of scope” section of the technical specification. Any grand, unrealistic ideas from stakeholders need to be confronted with experience-based evidence from the project manager.

  • Other internal departments such as purchasing need specifications documents to procure materials.
  • In construction, controlling risk is essential to managing end-to-end project lifecycle.
  • The scope section outlines the product’s features and functionality, performance targets and metrics that define success, any constraints and limitations, and key assumptions and risks.
  • Sometimes the term specification is here used in connection with a data sheet , which may be confusing.
  • You’ll also need to compliance with any relevant standards and regulations.

For example, it was easy when a soda company had one bottle and one can and one label to manage. Now, there are tens of different flavors, various packaging sizes, and languages that have made this data impossible to manage using legacy systems. Let’s walk through an example of how you might put together a product specification with a discovery process. If you’d like to follow along and create your own product specification document as you go, you can use our free template. A product specification is a document that outlines the characteristics, features, and functionality of a product. It serves as a blueprint for designing, developing, and testing the product.

By including construction specifications early in the project lifecycle, performance requirements are established from the start and project risk is reduced on a whole. To improve your construction specifications, and in turn, the success rate of your project, it starts with a firm understanding of what these documents are and how they are prepared. To design a specification, you must capture all of the technical details and performance specifications of a product. There’s often many formats professionals design specification in, leading to difficulty in processing and analyzing data. Specright’s patented Specification Management platform offers hundreds of specification templates to ensure your supply chain is on the same page. The importance of specifications goes far beyond project management and supply chain management.

Technical specifications are wordy documents by nature, and our template will help you trim the fat without losing any vital details to set you up for a successful project. Because of the nature of technical specifications, these documents can get pretty detailed. The set of requirements you include will depend on the product you are building. Case in point is this technical specification by NetBit for a 650 Watt DC-DC Power Module.

What are the Advantages of Specifications?

The type of specification can relate to the project or the procurement route – whether it is performance-based, prescriptive or proprietary – depending on project requirements. Specifications A detailed, exact statement of particulars, especially a statement prescribing materials, dimensions, and quality of work for something to be built, installed, or manufactured. Architects and designers typically define construction specs before a project, but project engineers or professional specification writers may as well. Construction specifications, or specs, detail the work and workmanship required for each construction project. A specificationis documentation of a precise requirement or list of requirements, which has not necessarily received certification by an official standards authority.

Specifications are most important for external interfaces that must remain stable. A design or product specification describes the features of the solutions for the Requirement Specification, referring to either a designed solution or final produced solution. Sometimes the term specification is here used in connection with a data sheet , which may be confusing. A data sheet describes the technical characteristics of an item or product, often published by a manufacturer to help people choose or use the products. A data sheet is not a technical specification in the sense of informing how to produce.


A specification should be as detailed as possible to avoid any ambiguity or misunderstanding. It should also be concise so that it can be easily understood by all parties involved. In this blog post, we will explore what a specification is in business and why they are important. We will also provide some tips on how to write a good specification. Although plans and certain documents can illustrate what a building should look like visually, an in-depth written explanation is needed to describe the construction process. Simply put, construction specifications are documents prepared ahead of construction to describe how building should be carried out by contractors and subcontractors.

The purpose of a specification is to ensure that what is delivered meets the needs of the customer or user. By being clear, concise and information-rich, a specification provides answers to many onsite construction questions, saving the project team, client and contractor time and money. Break down your objectives and then organise your specification into component parts with a clear and logical flow. Include an introduction, then background, scope of services and detailed requirements. Make sure you incorporate information on your brand values so that suppliers can consider and adopt these. Think about what your requirements are – separating into ‘must haves’ and ‘nice to haves’ – and write in terms of outputs.

Some elements of the project may only become clear after trial and error. The estimates of time and resources needed may shift and change during the project. If there are any uncertainties on your roadmap, a technical specification helps identify them and their potential impact. For example, Mac OS X has many components that prefer or require only decomposed characters (thus decomposed-only Unicode encoded with UTF-8 is also known as «UTF8-MAC»).

However, just because you write all the details down does not mean you get everyone to agree or understand. Again, much of this may be standard in your organization but worth confirming those standards will still apply with any changes you make. Specifications are not the same as system requirements, which describe the type of hardware required for a software program to work on a computer. See our system requirements page for further information about this term. Here’s your chance to be specific about what your system can and cannot handle.’s technical specification template

A well-written specification can help to ensure that a project is completed on time and within budget. There are several benefits of having a specification when it comes to business. A specification can help to ensure that products or services meet the needs and expectations of customers or clients. It can also help to improve communication between businesses and their customers or clients, what is specification as well as between different departments within a business. Further, a specification can help businesses to better understand the requirements of tenders or contracts, and ultimately save time and money. Finally, having a specification can give businesses a competitive edge by demonstrating to potential customers or clients that they have a clear understanding of their needs.
