E-learning or classroom training: comparing costs and outcomes

Understanding training costs and ROI

ROI = (Be­ne­fits gen­er­ated − Costs in­curred) ÷ Costs in­curred × 100. Costs in­clude direct in­vest­ment, such as pro­viders and the plat­form, and in­dir­ect costs, such as learner time and lo­gist­ics. Be­ne­fits must be ex­press­ible in mon­et­ary terms: pro­ductiv­ity gains, fewer errors or sav­ings.

Design­ing online con­tent may ac­count for a sub­stan­tial share of the ini­tial in­vest­ment. Add host­ing, li­cens­ing, ac­cess­ib­il­ity, up­dat­ing, tu­tor­ing and change-man­age­ment sup­port costs before com­par­ing formats.

Ex­am­ine the ar­range­ments offered for businesses before cost­ing the pro­gramme: tools, con­tent and sup­port must be in­cluded within the scope of the com­par­is­on.

Comparing the factors that create value

Scale and leverage

For large num­bers of learners, online con­tent can be reused without or­gan­ising a new ses­sion each time. How­ever, design, host­ing, up­dat­ing and sup­port costs, along with learn­ing time, must still be in­cluded; the com­par­at­ive cost de­pends on the pro­gramme.

Flexibility and training time

An online format can make remote access and varied sched­ules easier. It does not ne­ces­sar­ily reduce learn­ing time or the impact on op­er­a­tions; classroom train­ing fa­cil­it­ates syn­chron­ous ex­changes but re­quires par­ti­cipants to come to­geth­er.

Learning quality and engagement

Classroom train­ing fa­cil­it­ates direct ex­changes and cer­tain group prac­tic­al activ­it­ies. An online pro­gramme can offer scen­ari­os, activ­it­ies and tu­tor­ing, but no format alone guar­an­tees en­gage­ment or re­ten­tion: com­pare out­comes against the in­ten­ded ob­ject­ives.

Conditions to examine for an online programme

Un­clear ob­ject­ives or in­suf­fi­cient sup­port can limit a pro­gramme's use­ful­ness, whatever its format. To or­gan­ise mon­it­or­ing, see the five indicators for evaluating internal training.

• Thought­ful in­struc­tion­al design and active learn­ing.
• Rig­or­ous im­me­di­ate and follow-up eval­u­ation, with con­tinu­ous ad­just­ment.
• An ad­op­tion plan, light-touch tu­tor­ing, re­mind­ers and man­ager in­volve­ment.

When classroom training remains relevant—and where blended learning fits

Tech­nic­al work­shops, role-play and group de­brief­ings can jus­ti­fy an in-person ses­sion. A blen­ded format al­loc­ates activ­it­ies ac­cord­ing to their re­quire­ments: remote pre­par­a­tion and sup­por­ted prac­tice, for ex­ample. See moving from classroom training to blended learning.

Compare costs while keeping the learning provision equivalent

An eco­nom­ic com­par­is­on be­comes mis­lead­ing if the remote pro­gramme no longer offers the same pro­vi­sion. Write a com­par­is­on spe­cific­a­tion cov­er­ing skills, audi­ence, start­ing level, de­liv­ery con­di­tions and ex­pec­ted evid­ence. Spe­cify ne­ces­sary travel and paid time. A cheap­er pro­gramme that cannot be used in the work­place is not an equi­val­ent option.

Sep­ar­ate fixed costs from volume-re­lated costs. In­struc­tion­al design and ini­tial ac­cept­ance test­ing may be fixed; tu­tor­ing, some li­cences and train­ing time vary with en­rol­ments. Some costs in­crease in steps: a new cohort may re­quire an ad­di­tion­al tutor. Do not assume that a per­fectly linear curve de­scribes real­ity. Ask the sup­pli­er about billing rules and pack­age limits.

The de­liv­er­able is a spread­sheet in which every line in­cludes a unit, quant­ity, price, source and un­cer­tainty. An es­tim­ate without a quo­ta­tion is still pos­sible, provided it is iden­ti­fied as an as­sump­tion. Do not con­fuse budget­ary cost with eco­nom­ic cost: the time of an em­ploy­ee who is already paid may not gen­er­ate a new in­voice, but it still uses a real re­source.

Calculate a cost crossover point rather than promise ROI

The cost cros­sov­er point an­swers a lim­ited ques­tion: at what number of par­ti­cipants do two op­tions cost the same? If their costs are rep­res­en­ted by a fixed amount F and a vari­able amount v per person, equal­ity is ex­pressed as Fd + vd × N = Fp + vp × N, where d de­notes dis­tance learn­ing and p de­notes in-person learn­ing. The cros­sov­er point is there­fore (Fd − Fp) ÷ (vp − vd), but only when the de­nom­in­at­or is non-zero and these as­sump­tions remain valid. This cal­cu­la­tion demon­strates noth­ing about learn­ing ef­fect­ive­ness.

Marc then checks what hap­pens if the pro­ced­ure changes twice a year, if a quarter of those en­rolled re­quest en­hanced tu­tor­ing, or if an in­tern­al room be­comes avail­able free of charge. He builds three scen­ari­os—cau­tious, cent­ral and fa­vour­able—with their as­sump­tions vis­ible. If the choice changes as soon as a single as­sump­tion shifts slightly, the re­com­mend­a­tion must remain con­di­tion­al and jus­ti­fy a pilot rather than im­me­di­ate rol­lout.

• State the period: ini­tial year, second year or the pro­gramme's total dur­a­tion.
• Avoid count­ing travel sav­ings twice along­side time sav­ings already in­cluded.
• Dis­tin­guish po­ten­tial sav­ings from sav­ings that can ac­tu­ally be re­leased from the budget.

Do not attribute programme effects to the medium

The report by Means and colleagues, 2009 version, in­cludes 51 in­de­pend­ent ef­fects fol­low­ing study se­lec­tion. It ob­serves, in par­tic­u­lar, that the blen­ded ap­proaches com­pared often in­clude more learn­ing time or ad­di­tion­al in­struc­tion­al ele­ments. The au­thors there­fore warn against at­trib­ut­ing dif­fer­ences to the medium itself. Most of the evid­ence con­cerns post­sec­ond­ary or pro­fes­sion­al train­ing con­texts; it does not es­tab­lish the ROI of a com­mer­cial plat­form.

For your com­par­is­on, record the actual amount of learn­ing: activ­ity dur­a­tion, op­por­tun­it­ies to prac­tise, help re­ceived and train­er ex­per­i­ence. If the di­git­al pro­gramme adds cases with feed­back that were absent from the ori­gin­al course, you are eval­u­at­ing a pack­age of changes. That com­par­is­on is useful for de­cision-making, but it does not isol­ate the effect of remote de­liv­ery. State this lim­it­a­tion ex­pli­citly in the de­cision paper.

Choose an as­sess­ment common to both op­tions, using situ­ations dif­fer­ent from those en­countered during train­ing. Have work marked against the same rubric and, where pos­sible, without identi­fy­ing the par­ti­cipant's group. Doc­u­ment with­draw­als and ab­sences: an option may appear better if only the par­ti­cipants with the most avail­able time finish. With a small sample, present the find­ings as ex­plor­at­ory rather than defin­it­ive evid­ence.

The res­ults table must retain the num­bers en­rolled, as­sessed and provid­ing usable re­sponses. An av­er­age without these de­nom­in­at­ors hides in­form­a­tion losses. Also plan a later check­point, suited to how fre­quently the skill is used, to dis­tin­guish im­me­di­ate suc­cess from reuse at work.

Present an economic decision with its conditions

The paper for man­age­ment can fit on two pages: op­er­a­tion­al prob­lem, op­tions com­pared, full costs, ex­pec­ted out­comes and un­cer­tain­ties. If be­ne­fits cannot be mon­et­ised using a de­fens­ible method, present a cost per person who has demon­strated the skill, to­geth­er with the cri­ter­ia used. This ratio is not ROI: it com­pares ex­pendit­ure with a learn­ing out­come without ar­ti­fi­cially as­sign­ing it a fin­an­cial value.

To mon­et­ise avoided errors, you need to know their baseline fre­quency, av­er­age cost and what other changes oc­curred. A new pro­ced­ure, a change in cus­tom­er mix or dif­fer­ent equip­ment could ex­plain the trend. Clas­si­fy be­ne­fits by strength of evid­ence: direct ob­ser­va­tion, doc­u­mented es­tim­ate or as­sump­tion. An ex­plained range is more useful than an im­press­ive per­cent­age cal­cu­lated from in­vis­ible as­sump­tions.

Fi­nally, set con­di­tions for re­as­sess­ment: in­suf­fi­cient volume, a major con­tent change, access dif­fi­culties or learn­ing out­comes below the ac­cep­ted min­im­um. The final de­liv­er­able com­bines a re­com­mend­a­tion with the con­di­tions under which it holds. This makes it pos­sible to defend a blen­ded or classroom choice without deny­ing the eco­nom­ic be­ne­fits of remote reuse when the con­text makes them real.

Key takeaways

No format max­im­ises ROI in every con­text. Com­pare full costs and out­comes rel­ev­ant to your ob­ject­ives, test the chosen pro­gramme and adjust it using data and feed­back.
