Product Size Spec

The Size Spec tab houses your Product’s graded measurements as well as your Sample measurements.  Building your Specs is made efficient by dynamic linking to your POM Library and your Block Library.

Navigating the Size Spec

  • When you first open the Size Spec, you land in Point of Measure Mode.  Switch to Measure Mode or Compare Mode using the dropdown menu in the top left-hand corner
  • The Settings Drawer on the right of the page has options to change your Spec’s layout, value format, and Unit of Measure
    • In Measure Mode, the Settings Drawer has additional options for sample management
    • Expand or collapse the Settings drawer using the Gear button
  • The search bar at the top of the page allows you to query for and add Points of Measure from your POM Library, or create and add brand new POMs The Sort selector at the left of the page allows you to switch between your manually-set (custom) POM order to an alphanumeric sort
  • The Hide Fields selector allows you to hide POMs, columns, and samples from view.  Your available options here update as you switch ModesThe 3-dot Overflow Icon at top right allows you to access several other important Spec functions, including Edit Mode (where you add your sizes), Import Block, Download CSV and more
  • Within the Spec table, you can navigate from cell to cell using your arrow, tab, and return keys

Point of Measure Mode

Use Point of Measure Mode to build your Graded Measurements table.   Best practice is to start by adding Sizes, then POMs, and then Base Measurements and Grade Rules.

Defining your Size Range
  • Open the Overflow Menu by clicking the 3-dot menu at top right and select Edit Size Spec
  • In the Edit Spec Overlay, select your desired Unit of Measure and Measurement Format
    • Note you can switch UOM or Format in the Settings drawer later as needed
  • Choose between Alpha, Numeric or Alphanumeric Size Ranges
  • Key your first Size in the type bar, hit enter to add it, and repeat for each Size
    • To correct mistakes, click into the affected Size chip and retype
    • Drag and drop to rearrange Size chips as needed (these should be kept in sequential order)
  • Indicate which Size is your Sample Size by selecting the radio button on its chip
  • Saving redirects you to your table in Point of Measure Mode
Adding Points of Measure
  • Using the search bar at the top of the page, query for Points of Measure you previously built in your POM Library
    • POMs are searchable by Name or Code
  • An option to Create new POMs also appears below search bar, if you find no existing match
    • The only required field in the Create New POM modal is POM Name
    • A POM Code is automatically generated if you don’t add one yourself
    • Assign the balance, optional POM attributes as needed (see more details on POM attributes here)
    • Click the Add to POM Library checkbox for POMs you wish to reuse in the future; otherwise leave as a “one-off” POM which lives only on this Spec
  • POMs display alongside all their attributes, with columns to assign Tolerances, Sample Size Measurements and Grade Rules for each graded Size
  • If certain POM attribute columns are not applicable to your business, hide them from view using the Hide Fields dropdown selector at top right
    • Hidden POM attribute fields do not appear on Tech Packs
    • Your hidden/exposed POM attribute field settings persist across all Specs and Blocks
  • Edit POM attributes by clicking the POM Name
    • If the POM comes from your POM Library, clicking its name opens its record in another tab
      • Updates to POM attributes for Library POMs flow out to every Spec and Block using that POM
      • Review the list of Products and Blocks using the POM before saving changes
      • Use checkboxes to exclude certain Products/Blocks from your change if needed
      • See more on change management for POMs here
    • If the POM is a one-off, clicking its name opens a modal rather than another tab
      • Any changes made within this modal will affect only the current Spec
  • Click the leftmost cell of each POM row to access the 6-dot handle, and drag-and-drop POMs to your desired order 
Adding Base Measurements, Grade Rules and Tolerances
  • Select your preferred Spec Format in the Settings Drawer
    • Base Measurement Format is the most focused view, collapsing all Size columns beyond your Sample Size - it’s great for entering Tolerances and Base Measurements
    • Combined Measures Format includes your Base Measurements column, and the graded columns display both your Grade Rules and the Graded Measurements they yield.  This view makes it easy to check your math as you grade.
    • Grade Rules Format shows just the Base Measurements and accompanying Grade Rules.  This view can make it easy to spot typos.
    • Graded Measurements Format shows you the complete set of measurements.  This is the view you’ll most likely share with your factory.
  • Click the Gear button to collapse the Settings drawer for better visibility on bigger specs/smaller monitors
  • Enter in the correct Tolerance for each POM
    • You may have predefined the Tolerances on each POM record, but they can be overwritten here as needed
  • Enter the Base Measurements for each POM in the highlighted Sample Size column
  • Enter the Grade Rules for each POM in the columns for the balance Sizes
    • Grade Rules can be entered in Combined Measures Format or in Grade Rules Format, whichever you prefer
    • Grade Rule values are automatically set to negative for Sizes smaller than your Sample Size, and positive for Sizes larger than your Sample Size
    • Right clicking a Grade Rule cell opens a menu with the option to Flip Grade, should you need to switch from a positive to a negative Grade Rule (or vice versa)
  • For POMs where the Grade Rules are consistent across all Sizes, use the Copy Grade feature to speed up your process:
    • Right click in a Grade Rule cell to open a menu with the option to Copy Grade
    • Select this option to push the assigned Grade Rule from left to right, establishing a steady grade for the whole Size Range
    • Affect more than one POM at a time by selecting multiple Grade Rule cells in the same column, then right clicking and using the Copy Grade function
Importing Graded Specs

Importing data speeds up the process of creating your Size Spec.

  • Start by opening the 3-Dot Overflow Menu at top right
  • You have three ways to import, but we recommend using the Import Block option as a best practice (See also:Creating a new Size Block)
    • Select the Import Block option
    • Query your Block Library by Name or Code
    • Select the correct Block using the checkbox and click Continue
    • Add the Block by clicking Merge or Replace
      • Merge will append the contents of the Block to any content already in your Spec (use with caution - you should not Merge a Block into a Product with a different Size Range and/or Sample Size)
      • Replace will wipe out any content you previously added to the Spec, leaving only the content from the Block
  • The Import from Product option works the same way as the Block option, but you query your Product Library by Name and Code rather than querying your Block Library
    • Note that any Sample Measurement data from the source Product will not copy over, only the Graded Measurement data comes through
  • How to Import from CSV:  
    • Ensure that your .CSV file matches the "Sample Template". The format requires the following column headers: 
      • POM Name
      • POM Code
      • Tolerance (+ / -)
      • Sizes across the columns (S, M, L, XL, etc...)
      • Sample Size
    • The following column headers are optional and may be left blank:
      • How to measure: this will import any entered values. Blanks will import blank.
      • Critical: this will import any "TRUE" or "t" values as checked checkboxes and "FALSE", or "f" values as unchecked checkboxes. This is not case-sensitive. Blanks will import blank.
      • Type: this will import any "half" or "h" values as Half, and "full" or "f" values as Full. This is not case-sensitive. Blanks will import blank
    • Note: Backbone offers a "Sample CSV template" when opening the "Upload CSV" Module. See video above for further clarification.
    Tips and Tricks
    • The format of the numbers in the CSV should be either all in decimals, or all in fractions. If there is a mixture, all values will be converted to decimals upon import.
    • The measurements and tolerances can be formatted to millimeters, centimeters, inches, feet, yards, or inches and must match the dropdown when importing
    • There should not be any additional blank rows in between your POM rows
    • Enter a Sample Size (you only need to do this once)
    • You can add any POM Names and Codes you'd like. You do not need a code, Backbone will auto-generate one if you don’t provide one.
      • Note that importing from a .CSV does not link imported POM's to your POM Library
    • The template is originally a .xlsx file, be sure to file > save as > .csv when saving in Excel.
Additional Functionality in Point of Measure Mode
  • The 3-dot Overflow Menu at the top right of the page has these additional options:
    • Download a CSV of your Graded Spec
    • Copy your Graded Spec into your Block Library
    • Clear your entire Spec (note this includes any Measure Mode / Compare Mode data)
  • In the Settings Drawer, you can convert your measurements to a different Unit of Measure or toggle between fraction and decimal format

Measure Mode

Use Measure Mode to record and analyze the measurements of your development samples.

Adding Samples
  • Use the dropdown menu at top the left-hand corner of the Spec page to switch from Point of Measure Mode to Measure Mode
  • Notice the options in your Settings drawer change as you switch Modes
    • You can expand or collapse the Settings drawer by clicking the gear button
  • Click the Add New Stage option at the top of the Settings Drawer
  • A pop-up modal appears, where you name your Sample and (optionally) mark the Date Received
    • The Development Stages configured in your Admin panel appear as naming suggestions for the Sample
    • Use one of these suggestions or free-type a different Name if you prefer

  • Click Save, and a dynamic measurement table for the Sample appears  
  • The default size for the measurement table is your Sample/Base Size
    • Switch to a Graded Size table in the Settings Drawer when needed
  • Note that Samples added from within Measure Mode will dynamically appear in the Samples Tab; these two sections are linked
    • Samples Requested in the Sample Tab also appear in Measure Mode
    • Samples can only be deleted in the Sample Tab
Measuring a Sample in your Sample/Base Size

The Sample Size target measurements you defined in Point of Measure Mode will automatically appear in the Expected column.  Now you can enter your actual Sample measurements in the Received column of the table.  As you enter these values, see the Variance column dynamically update - these values are the difference between what you expected and what you received.  The Variance column values display in green if they are within the Tolerance you defined; they display in red if they are outside of Tolerance.

The Revised Spec column of the table is automatically filled with the Expected Values, since it’s likely you’ll want to change the target for just some of your Points of Measure, not all of them.  You can affect the Revised Spec values in one of two ways: 

  1. Type the new value directly into the Revised Spec column (ex. “The Across Shoulder measurement is 18 ¼ on the sample and works well.  Make 18 ¼” the new target”).
    • Notice your Adjust +/- column dynamically update accordingly.
  2. Type the incremental change you’d like to make, relevant to your initial Expected measurement, in the Adjust +/- column (Ex. “The Sleeve Length is on spec, but looks short in fitting - let’s add ½” to the target”).
    • Notice your Revised Spec columN dynamically update accordingly.

To clarify the Spec revisions you’re making, you can add a Measurement Status and/or a Measure Note.  The Measure Status column is pre-populated with the most common callouts (Back to Spec, Keep As Sample, etc.), but if you’d like to say something off the list, use the Measure Notes column. 

Since the Sample you measured is in your Sample Size, an extra column appears between the Revised Spec column and the Measurement Status column.  The column allows you to copy Revised Spec values to the Sample Measurements column of the graded table in Point of Measure mode.  Click the Copy Icon for each row to update individual POMs, or use the header-level Copy Icon to update the entire column at once.

Your Revised Spec values do not carry over to the graded table until you take this step.  Moreover, whenever you add a new Sample Stage, the Expected Values for the measurement table pull from the graded table -- they do not pull from the Revised Column of a previously measured Sample.  So, once you confirm your Revised measurements, it’s important to keep the graded table up-to-date by actively copying them over using this tool.

Measuring a Sample in a Graded Size

You’re able to track measurements for all Sizes within a single Sample Stage, should you need to.  This step is relatively uncommon in early prototyping, and relatively more common as you get closer to production and need to perfect the garment fit.

To measure a Sample in a Graded Size, change the Size selection in the Measurement Sizes section of the Settings drawer.  The Expected column values then repopulate; they are calculated based on the Sample Size values and Grade Rules you have in Point of Measure Mode at the time you add the relevant Sample Stage.  

You can enter your Sample measurements in the Received the column, analyze the Variances, and revise your targets using the Adjust +/- or Revised Spec column - just like when measuring a sample in your Sample Size.  You can also add Measurement Statuses or Measure Notes, but you cannot copy your Revised measurements to the graded table in this scenario.

Your revised target measurements for graded Sizes may be achieved by adjusting the Sample Size targets, or they may be achieved by adjusting the Grade Rules (or a combination of the two).  You can manage these nuanced adjustments within the Graded Table directly.

Managing Multiple Measurement Sets for the Same Sample

You may wish to track multiple sets of measurements for the exact same Sample.  For example, perhaps you need to track the factory’s measurement data as well as your own internal data.  Or maybe you want to compare measurements between two different Technical Designers.  

In such cases, add another measurement table to the same Sample Stage/Size by clicking the Add New tab at the bottom left of the page.  A modal appears allowing you to name the table something descriptive - like “Internal Measurements” or “Factory Measurements,” for example.  Click save, and a new table appears, where you can enter your data just as with the initial measurement set. 

The first measurement set you enter per Sample Stage/Size is considered the Default Measurement Set - this is the one which appears in Tech Packs.  If you wish to change the Default to a different Measurement Set, hover over its tab at the bottom of the page to access the 3-dot Overflow Menu, and then choose the Mark as Default option.  Through this menu you can also rename a Measurement Set or delete it, should you need to.

Hiding Fields in Measure Mode

In Measure Mode, certain POM fields are automatically hidden:

  • How to Measure
  • Type 
  • Critical

These fields, which appear as columns in the Measure Mode table, are hidden to allow space for Sample-level fields like Adjust +/-, Variance, Measurement Status, etc.

Any additional fields which were hidden in Point of Measure mode remain hidden in Measure Mode - like the Image or the POM Code columns, for example.  You can hide/unhide these fields within Measure Mode; but note these changes will also affect Point of Measure Mode.

The same goes for POMs - any POM rows which you hide or unhide in one Mode will be hidden/unhidden in the other Mode, as well.  If you mark certain POMs as Critical, you have a handy shortcut to hide all the others.  Open the Hide Fields menu, and at the top of the Points of Measure submenu, toggle the Show Critical Poms option.  This can be really useful when doing jump set or QA measurements, where some but not all POMs must be measured!

When in Measure Mode, you also have the option to hide Sample-level fields like Adjust +/-, Variance, Measurement Status, etc.  If you aren’t using one of these fields, hiding it will allow space for more relevant data in the measurement table.

Note that you may need to refresh your browser and/or toggle between Modes for your hidden field settings to take effect.

Any fields you hide within the Size Spec will be hidden on your Tech Packs, as well.

Additional Measure Mode Features

Stage Progress

Optionally, you may wish to manage your Stage Progress within the Settings Drawer.  The default setting is In Progress, indicating that a Sample has been received and measured, but that analysis and revisions are still pending.  You may wish to toggle Complete after fitting the garment and finalizing any revisions.  This setting isn’t reflected on the Tech Pack, it’s just visible internally, as a stage gate for larger teams.

Unit of Measure

The Unit of Measure can be adjusted via the Settings Drawer for both Measure Mode and Point of Measure Mode - the setting you select in one Mode will affect the other.  This can be a handy tool if you work best in inches, for example, but your factory prefers to work in centimeters.  Tech Packs will reflect the most recent UOM setting.

Sorting

Many teams build specs with the POMs organized to facilitate ease of measurement (front measurements in one group, back measurements in another group, etc).  However, when looking for a particular POM in larger specs, it may be useful to sort alphabetically instead.  The Sort by menu allows this option; and you can always revert to your Custom sort afterward.
