# Creating a new cycle
When you start a new cycle, you will be taken through a wizard in which you define some basic traits of your cycle.
# Basics of your study
The basics of your product include:
- Name: how your cycle will show when searching for it.
- Scope: which stages of the life cycle you are interested in. The default is full life cycle, but you can use this section to record whether your product is intentionally leaving some of those stages out.
# Template selection
You don’t have to model from scratch! Templates show how the average product in a category is made. If you’re using a template, you’ll start with average data for each life cycle stage in your model.
Bear in mind that templates are only a starting point. Once loaded, you will be able to adjust the values and edit the flows to reflect your specifics, focusing on what matters most.
You can toggle off the use of a template altogether, and you will start with an empty cycle.
Note: starting with an empty template is recommended only for more advanced users, since you will receive much less guidance from the get-go.
You can enter keywords to search in our template database. Your geography will be auto-detected from your location if you let us do so, otherwise you can select it in the settings. Setting your geography here also streamlines your selection of data from this point onwards: we will prioritize processes that are relevant to your geography.
Once you start typing you will receive suggestions of templates. Pick the one that is most similar to your product and click next to continue.
# Scale: what and how much?
After clicking on next you will be taken to the second and last section of the wizard, where you will be able to select the scale of your cycle. The scale represents the different ways of measuring your cycle (are you creating a model for 1 pencil or 1 metric tonne of them?).
Note: Read more about the similarities and differences with the Life Cycle Assessment term of Functional Unit here.
# Types of units
For a new cycle, you are asked to input one or more of the following:
- Production unit: measures of how much physical units you are producing. This can be measured in units of a given product, mass (kg, lb) or other physical units.
- Functional units: measures of the functional output of the life cycle. The reason why we produce products is in order to do something with them. When we compare two alternatives, often the only way to draw meaningful conclusions is to compare these functional units. It can be measured in almost any type of units (number of uses, distances, time used, etc)
For each, you can edit the values and units, to suit your cycle.
One special case is your template's units. They are a particular case of production unit, used to adapt the template to your particular use case. Templates are typically measured in currency units, in prices paid to producers, before distribution. To make sure you input the right numbers, we calculate the ratio between your production unit and the templates'. This acts as a safety check.
# Functional units
Measuring the functional output of a cycle is, for many professionals, one of the most difficult tasks. In some cases, these units will evolve as the project becomes more mature (do not worry, you will be able to edit these later).
Because of that, we provide some guidance by asking the user to phrase the function clearly in words to start with. In our experience, this makes the process of defining its units much simpler.
Once the function is described, you can define one or more units for measuring this function. You can define more than one way of measuring, in a way that all those measures are equivalent.
For example, if we were modelling a printer, and our production unit is 1 printer, we could define as functional units 6 years of use or 2000 pages printed. All those units are equivalent for a
Describe the function of your product in words, and then specify one or more units for measuring this function. Later you’ll be able to compare your product with other ways to provide an equal function.
