Ensuring our customers have the help/support they need

Commitment

Whether you are a current or prospective customer we want to ensure all our customers (current and future) have the support they need this coming year.

We are committed to your successful use of Cradle and provide a range of support services to ensure that Cradle delivers optimal benefit to your projects.

Options

Prospect Support

We’ll help you get your evaluation up and running and assist with questions on setting up for your company’s process.

Single User Products

These extremely competitively priced products come with 7 days active support. After that you can use the LinkedIn discussion groups, online help, online videos and bundled user manuals. Users may upgrade to any point.point releases denoted by their licence, e.g. 7.3 users may install 7.3.1 and 7.3.2

Enterprise Support

Enterprise products with maintenance are covered by unlimited active support from 3SL and their partners. They also have access to online material as above. Users can upgrade for free to any later product versions during their maintenance period. Users with Named User Licensing are able to request a number of user changes each year for free. Additional licences for extra features or personnel may be purchased at any time.

Product Re-instatement.

Whilst we wish all our customers have continued use for Cradle, we do understand that some long term projects go through design quiet phases. It may be that during these lulls following product design/development or test software tools are ‘parked’.  3SL will endeavour to re-instate any old projects and bring users up to the latest version of Cradle once the maintenance gap is filled, or a later version of the product purchases. We strive to ensure a full upgrade path and compatibility of all you historic Cradle data.

Training

We can supply a number of off the shelf Cradle training courses. However, to ensure you get the best benefits from these, we will consult with you to tailor the course for your company’s needs.

Bespoke Development

Whilst Cradle offers a full suite of products that cover most of our customers needs, some functionality requests are very bespoke. For example if you are using the WebAccess product and require customised pages with your company logo, you’re free to alter the templates. If, however, you have not got the expertise in-house, 3SL would undertake funded work to do this. Custom applications and new product features are also undertaken and 3SL will be happy to discuss your requirements.

Handwriting Day 2018

Handwriting

The art of a carefully crafted sentence with beautiful ink on a crisp page is becoming a rarity. Handwriting day serves to remind us of that skill.

These days we can even create ‘handwriting’ in our electronic documents with cursive fonts. We can Digitally sign documents using a pass-phrase. However, there is still room for a quick hand written posty note, a card or a signature on a document as a stamp of authority.

Storing Handwriting in Cradle

There are a few ways that you could store hand written information  in Cradle.

  • As an image
  • As part of a PDF / Word Document /RTF document.
  • As part of some other user defined binary frame

Coupled with ‘Skills’  restricting access to the frame storing the signature, Cradle can also protect access to say a signature  of authorisation.

Handwriting in Cradle

Whether it is a handwritten requirement / letter / alteration  from your customer or an authorisation signature, you can store them in Cradle. As part of Change Management you may wish to record a picture of a whiteboard discussion, a snapshot of the back of that envelope or even a scan of the letter sent by a customer.

In this month’s newsletter we asked you to email us when you last “hand wrote  a date”. There’s still time to drop us a line and get a mention  next month. Or if you really want to practice your writing for handwriting day 2018, drop us a letter.

Baselines – The end of the road in Configuration Management?

End?, No Way! A Baseline is just the beginning……

Divide and conquer bound, line in the sand
Clichés

When you have a complex problem, it is always good to ‘set some bounds’1, ‘divide and conquer’2 and ‘place a line in the sand’3. That’s 3 so far on the cliché count, but they are all true reflections of baselines and configuration management processes.

Baselines and Configuration Management. No real life project is static, it never has all the answers available up front and even the most basic of tasks is likely to have a change to its requirements. Changes can range from an alteration of delivery date or change of colour, to a whole change in direction caused by a change in circumstances, finance or regulation. If we’re not careful, project managing this changing landscape4 the ever changing goal posts5 puts project completion at risk.

We need to be clear that the proposed system requirements matched up to the user requirements at a particular point in time. Recording a baseline is that proverbial ‘line in the sand’. A baseline records the conditions at a point in time. The initial user requirements right at the beginning of the project would make an ideal baseline. It gives us a foundation to work from6. From there we can record, measure and control how the project develops. Far from being the ‘End’ of a project lifecycle, a baseline is a really good beginning.

Point of Decision

Now that we have our foundation, we can decide whether it is solid enough to build on. At present it may be more akin to a trench with some hardcore in the bottom, and nothing ready for a wall. However, we can now discuss these baselined requirements/or characteristics before moving on.

Foundations
“Is the wall definitely in the right direction?”,  “Is the wall to terminate at the end of the garden and no further?” (Setting the bounds) “Are you happy for us to quote for the full wall on this basis, or do we need to set a half-way house7 at the first course and then re-evaluate?” (Divided and hopefully conquered).

If all is well we can specify the system requirements and get the concrete poured. This firming up of the foundations8 would be another good baseline point.

Managing Change

“The neighbours have complained, the wall is too short to keep the dog in”.  Back to the drawing board? Not quite, we can go back to the baseline and check what the agreed characteristics of the foundations were. We can’t build the wall higher in solid blocks as the  foundations were not laid with sufficient margin for the extra weight. However, building the top part of the wall in decorative open block-work will meet the changed requirement and satisfy the user. Costs adjusted, new quantities calculated and time to take a new baseline.

Whilst ideally the project would have been planned from start to finish, before the first components were laid, this is not always possible or practical in real life. Recording when and why changes were made will help us make decisions based on firm ground9, rather than walking on sinking sand10.

Garden Wall

Far from being end points, baselines should be seen as stepping stones to your goal11. However, they should not be seen as a linear path. There may be more than one path across the river12, and not all routes will lead successfully to the other side. Assume the neighbour decides to move and takes their dog with them. We can rewind to the baseline taken at the foundation stage and progress down the original planned height in solid bricks as we have the record that this was a possible solution at that point in time12.

Baselines and Configuration Management (CM)

CM is a process that aims to establish and maintain the quality and consistency of a system’s performance, functional, and physical attributes throughout its life. It is tightly linked to the Quality Management System (QMS) and Requirements Management System (RM/REQM) employed on a project. Deciding when and whether items should be baselined, would generally be subject to review (QMS). Providing traceability through the project’s lifecycle also a QMS function. Gathering, eliciting, and decomposing requirements is an RM function. Dealing with change, would need elements of all three. Whilst it may be fun playing cliché bingo, it really is time to place a stake in the ground13 and record milestones in your project14. Don’t delay baseline TODAY!

Thesaurus Day 2018

Thesaurus Day Celebrate Variety

Happy #ThesaurusDay or Should that be “Convivial greetings to all celebrating alternative onomasticon listings day” ?

In pure terms a list of equivalent words or synonyms helps enrich our language. The thesaurus may list a number of alternatives that are subtly different.

Requirements ambiguity

When writing a requirement we have to be careful that we are unambiguous in both our language and meaning.

Language Construct

“The value displayed shall be the total time expended for each activity of a particular type divided by the count of all activities of each type”.  Could be interpreted as

A1 2mins, A2 1min, A3 4mins = 7 mins for type A
B1 3mins, B2 4mins, B3 8mins, B4 1min = 16 mins for type B

Value to display for A = (7 mins / 7 )  = 7
Value to display for B = (16 mins / 7) = 2.3

or as intended

Value to display for A = (7 mins / 3 )  = 2.3
Value to display for B = (16 mins / 4) = 4

In this case we could have removed the ambiguity by using an equation as a synonym for the language.

ValA = sum{typeA.duration} / count{type A}
ValB = sum{typeB.duration} / count{type B}

Meanings

Choices in language can mean different things to different people. This is especially true where suppliers and customers work in different fields. The Customer’s Requirement is their end goal, for the supplier it is the starting point. The Customer asks that the “After the office upgrade and IT installation users should have a clear desk”. Maybe unhindered or unobstructed would have served better?

ambiguity over a meaning
Clear Desk – What was envisaged & what was delivered

Stay SMART(U)

So to celebrate thesaurus day 2018 : Do your best to keep your requirements Specific, Measurable, Attainable, Relevant and Time-bound. Oh and of course Unambiguous, but rich with language.

New Year’s Resolution

We all make promises to ourselves, many we find hard to keep. Yet another sucker falls for the gym membership sign up and then decides binge watching that box-set is easier/more enjoyable/cheaper. It does really seem like the worst time of year to be making decisions to be getting out and about exercising. (Apologies, again, to our customers on the other side of the globe – read this again in 6 months !).

Data Exchange Microsoft® Project / Cradle

One resolution that should be easier to keep is to start afresh with plans for current and new projects. We’ve had time to allow our heads to clear over the Christmas break and should be facing work with a new vigour.  Planning is the key to ensuring schedules and expectations are met.  This may seem like a very un-Cradle® plug, what’s planning got to do with modelling and requirements? The answer is in fact quite a lot. Without a project management plan and schedule how would the capture, design, review and test be achieved in the right order? A Work Breakdown Structure can be used to segment activities, and component parts of a project into manageable chunks. The ability to link a plan from Microsoft® Project brings together the planning and implementation elements of your project. For more information see the Cradle Help on Project Capture

Controlling Your Initial View

Query with a View

Each query can have an initial View associated with it. Each time this query is run, it will apply the view. This is the best way of controlling your initial view for a particular query.

Shown in the screen shot below the project viewresults‘ has been set in the queryMy Results‘ each time this query is run the columns specified in the View Details are shown. There’s nothing to stop a user selecting a different view in the ribbon later.

showing the query, view setup and results
Initial View Settings

Remember that View

WorkBench is designed to remember the last view you used for a particular item type.  It’s likely that next time you run a query for the same item type, you’ll want the same view. Even if you close all your tabs, within the same session you are controlling your initial view of each query by the last choice you selected.

Initial Influence

You can control the initial view selected for a query in a project by associating a view with an item type in the project’s schema. Open Project Setup and select the item type and an appropriate view. When starting Cradle, this will be the view selected for this item type, the first time it it is queried. Thereafter, WorkBench will switch to  “Remember that View”.

setting an initial view in the schema
Initial View – Schema

QAB Queries and Views

The Quick Access Bar at the bottom of WorkBench as some auto generated queries and auto generated views for speed. If one of these is selected then the the view that is ‘remembered’ will be the last one of the Automatic views.

What’s a dangling cross reference?

Dangling Cross Reference

These are cross references in the Cradle database where one or both items at the end of the reference are missing.

It goes without saying that if you have item A linked to item B and then delete item B, the link between A and B should disappear. In usual operations this is true and this is what Cradle will do.

However, it is possible to create a dangling cross reference when importing partial data from other projects or backups. Say for example you have exported all your Definition items (one of which is item A) and separately all your cross references.  (including the one to item type Constraints one of which is item B). Into a new project you import all the cross references and then the Definition items. You plan to create new constraints. If one is not created called B there will be a dangling cross reference in the new project.

Finding and Rectifying Cross Reference Problems.

Cross Reference Integrity Checker

Dangling cross references are just one of the  anomalies that can be detected using the cross reference integrity checker. This is run from the Project ribbon.

There are a number of tests which can be selected and these are shown below.

Once a problem has been identified, it can be fixed, deleted or exported for editing as appropriate. The availability of these will depend on both the problem and the current user’s privileges.

The cross reference integrity checker and report
Cross Reference Integrity

 

CheckDescription
Dangling cross referencesDetects cross references whose from or to item do not exist.
Duplicate cross references (A-B and B-A)Cross references are considered to be duplicates if a cross reference exists from item A to item B and another exists from item B to item A and they both share the same link type.
Reversed hierarchical cross referencesDetects cross references that are between items where the from item has an identity that suggests it to be the child of the to item.
Cross references to be reversedDetects cross references that are invalid according to the current link rules but which, if reversed, become valid.
Cross references needing a new link typeDetects cross references that are invalid according to the current link rules but which become valid if their link type is changed and where there is only one link type that is valid for the cross reference.
Invalid cross referencesDetects cross references that are invalid according to the current link rules.
Cross reference cardinalityDetects cross references whose cardinality does not match the current link rules.
AllWill perform all the above integrity checks.

Performance

Dangling xrefs can cause issues with performance when items have been deleted. If item A was linked to item B, then item B got deleted. There would be a dangling xref which isn’t linking any items, creating extra data. If another item B was then created. It would then be linked back with item A. Which could potentially cause problems?

Special characters in regexes and how to escape them

Regex – Regular Expression

Cradle provides support for regular expressions, regular expressions are a means to find variable text in places such as:

  • Queries
  • Find dialogs
  • Category recognition strings
  • Category value validations

For instance, regular expressions (regexes) can be used in queries to find all items in which any frame, or a specific frame, or any of a list of frames, contains text matching the regular expression that you are searching for. For example, if you wanted to find all items containing sequences of capital letters followed by numbers, then the regular expression would be:

[A-Z]+[0-9]+


Whilst you are here, take a look at Why is Requirements Management Essential for your Business?


Special Characters

Some characters have special meanings within regexes these characters are:

CharDescriptionMeaning
\BackslashUsed to escape a special character
^CaretBeginning of a string
$Dollar signEnd of a string
.Period or dotMatches any single character
|Vertical bar or pipe symbolMatches previous OR next character/group
?Question markMatch zero or one of the previous
*Asterisk or starMatch zero, one or more of the previous
+Plus signMatch one or more of the previous
( )Opening and closing parenthesisGroup characters
[ ]Opening and closing square bracketMatches a range of characters
{ }Opening and closing curly braceMatches a specified number of occurrences of the previous

Examples

Finished\? matches “Finished?
^http matches strings that begin with http
[^0-9] matches any character not 0-9
ing$ matches “exciting” but not “ingenious
gr.y matches “gray“, “grey
Red|Yellow matches “Red” or “Yellow
colou?r matches colour and color
Ah? matches “Al” or “Ah
Ah* matches “Ahhhhh” or “A
Ah+ matches “Ah” or “Ahhh” but not “A
[cbf]ar matches “car“, “bar“, or “far
[a-zA-Z] matches ascii letters a-z (uppercase and lower case)

Using Special Characters as Literal Characters

If you want to use any of these as literal characters you can escape special characters with \ to give them their literal character meaning.

Example

If you want to match 1+2=3, you need to use a backslash (\) to escape the + as this character has a special meaning (Match one or more of the previous).
To match the 1+2=3 as one string you would need to use the regex 1\+2=3

For further information on using regexes in Cradle see our online help.
